Ошибка p0522 jeep compass

Diagnostic trouble codes (DTC) that appear out of nowhere on your Jeep’s dashboard can be annoying. 

Additionally, it is a cause for concern if the code P0522 is discovered that indicates an issue with the oil pressure sensor. 

The code is considered moderately severe and needs to be fixed soon. Let’s dig in to find the relative causes and their potential fixes to get rid of the P0522 Jeep code.

What Does P0522 Jeep Code Mean?

The P0522 diagnostic trouble code in Jeep engines gets triggered when the oil pressure sensor detects an abnormal reading about oil pressure. 

An oil pressure sensor is installed within the engine, which detects and ensures the optimum oil level.

When the code P0522 is shown in the OBD2 scanner, the ECM has detected a low oil pressure signal from the sensor. 

First, let us look into the code itself and understand what it means by breaking it down.

• P = OBD-II powertrain (engine and transmission) related diagnostic trouble code.
• 0 = Manufacturer specific code for the DTC
• 5 = Speed control and Idle control code.
• 22 = Specific fault index for DTC. (In this case, 22 means the oil pressure sensor/Switch circuit low voltage.)

What Causes Low Oil Pressure and P0522 DTC Code on a Jeep?

The P0522 code specifies something fishy is happening with the engine oil pressure monitoring system. This code can pop up on the OBD-II scanner for several reasons.

However, the most common reasons could be a fault in the oil pressure sensor. Here, we have listed some major and associated causes for the P0522 code for Jees. Take a look at these to know if they match your Jeep.

• Low oil pressure
• Issues with oil quality
• Faulty oil pressure sensor
• Open/short in the oil pressure sensor switch wiring

The diagnostic trouble code (DTC) P0522 for a Jeep vehicle is present when pcm identifies low voltage from the sensor. 

As stated there are many reasons for which the code is set, finding out the right reason is an essential part to get rid of the code. 

Check out the following potential fixes to remove the P0522 code from your Jeep and keep your engine healthy.

1. Ensure Oil Level Is Optimum

When the oil pressure drops, less oil is delivered to the engine’s internal components, leading to increased friction and heat and potential damage to the engine.

The engine control module (ECM) monitors oil pressure through an oil pressure sensor and compares it to the predetermined values programmed into the ECM. 

If the oil pressure is lower than the programmed minimum, the ECM will set a DTC P0522. Several factors, such as low oil levels and clogged passages, can cause low pressure.

To fix this, remove the existing oil from the oil chamber and pour a fresh amount of compatible-grade engine oil into your Jeep. 

Additionally, replace the oil filter with a new one, which will keep the oil flow stable and free of debris.

Changing the oil and oil filter can charge you around $100-125, including the labor charges. 

Since this is the safest and easiest way to troubleshoot the P0522 code, you can give it a shot before going to investigate other elements.

2. Replace the Faulty Oil Pressure Sensor

Considering re-pouring oil doesn’t fix the issue, the cause for P0522 is more serious than it is anticipated. 

The oil pressure sensor measures the oil pressure in the engine and sends a signal to the engine control module (ECM). 

If the oil pressure sensor is not working properly, it can send an incorrect signal to the ECM, indicating low oil pressure when it’s not actually low. 

In this case, the ECM will set a DTC P0522 and illuminate the low oil pressure warning light on the dashboard. 

You cannot fix oil pressure sensors. Therefore, you must replace the faulty oil pressure sensor with a new and compatible one for your Jeep to fix the issue. 

The oil pressure sensor is located behind the fuel injectors. Hence it is very difficult to reach it if you do not have the proper tools. 

That is why it is recommended to take your Jeep to a certified mechanic to change the faulty oil pressure sensor. On average, you may have to pay around $120-$200 to replace the oil pressure sensor.

3. Check for Open or Shorts in Sensor Wiring

If your oil pressure is working fine then there must be an issue with the wiring connections. Aging impacts from corrosion, physical damage, or electrical faults causes an open or short in the oil pressure sensor wiring.

An open circuit in the oil pressure sensor circuit means your car’s oil pressure sensor is affected by damage, a rupture in the wiring, or a disconnected sensor. Hence, it prevents the ECM from receiving a signal from the sensor. 

On the other hand, a short circuit means an unintended connection between the sensor circuit and another circuit, which can cause the ECM to receive incorrect data.

When the ECM detects a low oil pressure condition, it activates the Check Engine Light and may put the engine into a reduced power mode to protect it from damage. 

A thorough inspection and overhauling of the wiring can solve this problem and you are good to go. This process requires a lot of disassembling and is tedious work. 

Thus you can get it fixed from professional spending around $200 or above including labor charges.

4. Issue with Oil Quality

Lastly, you must ensure the oil you are providing your Jeep is top quality and compatible with oil grade. If the oil is contaminated with debris or foreign particles, it can cause clogging of oil passages, leading to low oil pressure.

The engine may not sustain enough pressure if the oil is too thin or has lost some viscosity, resulting in a low oil pressure warning. 

Besides, considering the engine consumes more oil than it should, the oil level can drop too low, causing low oil pressure.

To fix this, all you need is to remove the old oil and oil filter and pour it into the manufacturer-recommended oil, followed by resetting the DTC.

Эпопея с системой охлаждения!

О замене бачка писал, опишу проблему подробнее, возможно кому-то пригодится.

Из бачка стал уходить антифриз, видимых потёков не было, я напрягся и стал наблюдать. 

Смотрел на уровень в бачке после ночной стоянки, система ж должна остыть, давление выровняться. Во время пуска двигателя смотрел на выхлопные газы. Почитал статьи про систему охлаждения, все пишут про прогоревшие прокладки, в общем жуть. Продолжалось это несколько месяцев. Антифриз периодически уходил, а я его подливал. Однажды поднял капот сразу после поездки по городу и вижу блестит коса проводов, которая проходит примерно под бачком. Трогаю её пальцем — палец красный. Думаю вот оно. Начинаю лазить искать. Включил фронтальную камеру на телефоне и засунул телефон под бачок, а там висит капля и дренажная трубка мокрая.
 

Всё вытер, выровнял уровень в бачке и стал ждать. А антифриз не уходит. 

В итоге моих наблюдений оказалось, что на самом дне бачка, в самой его нижней точке, похоже образовалась микротрещина. При езде по городу, когда система охлаждения максимально разогревалась и создавалось максимально высокое давление, бачок начинал течь. Но тёк не сильно, поэтому до утра в подкапотном всё высыхало. 

При этом автомобиль 2017 года, какого хрена бачок треснул непонятно.
Поставил новый бачок, заменил на нём крышку, и уже как порядка 2000 км этой проблемы нет. Но фобия осталась и литр антифриза всегда лежит в багажнике. 

Всем добра и крепких бачков!

P0522 is an OBD2 diagnostic code that is triggered when your Jeep Compass detects that the value being sent from the oil pressure sensor is below its normal operating ranged.

It is typically caused by a bad oil pressure sensor or an issue with the oil system, and should be diagnosed and fixed right away.  While it is possible (and even likely) that the oil pressure sender/sensor is bad, there could also be a problem with the oil pressure.

Assume that you do not have any oil pressure until you confirm that you do.  If there isn’t any oil pressure, this can keep the engine from locking up. 

Your Compass’s oil pressure sensor measures the oil pressure mechanically, and converts that reading into a voltage signal that the PCM (Powertrain Control Module) uses for the oil pressure reading.  This reading is what you see on your oil pressure gauge and triggers the oil warning light.

P0522 Quick Facts

• Most often caused by an issue with your Compass’s oil pressure sensor or circuit
• Should be taken very seriously
• The most common symptom is the oil light or an improper oil pressure gauge reading
• Easy to diagnose

P0522 Symptoms:  Jeep Compass

Here are the most common symptoms of P0522:

• Low Oil Light/Gauge- While P0522 is often caused by a bad oil pressure sensor, you should treat the readings from the oil pressure gauge and low oil warning as though they are correct until you know better.
• Ticking and Knocking- If your engine is ticking and knocking, it’s likely that the oil pressure sensor is accurate and there’s a problem with the engine or you need oil.
• Won’t Start–  If there was no oil pressure, your Compass’s engine very well could have locked up.

Compass P0522 Causes

P0522 is going to be caused by an issue with the sensor or sensor wiring (which would mean your engine is fine).  Or it is going to be caused by an issue your Compass’s oil level, viscosity, pressure, or cleanliness.  

Since proper oil flow is so critical to the engine, this code should be treated with respect and not ignored.

Here are the most common causes of P0522:

• Low or No Oil- The first thing that you should do is check to see if there is oil in your Compass’s engine at all.  If the crankcase is empty or really low on oil it can throw P0522.  If this is the case, fill the oil back up, clear the code, and that may fix the problem.  
• Low Oil Pressure- If the oil pressure level is too low, this code can show up.  It should show up with the oil light, or a low reading from the oil pressure gauge.  Jeep Compass Low Oil Pressure Diagnosis
• Dirty or Wrong Oil- If there hasn’t been an oil change for a long enough period of time, it can interfere with the oil pressure sensor, even if there still is oil pressure. 
• Oil Pressure Sensor Wiring- P0522 indicates that the signal from the oil pressure sensor below it’s operating range.  This could indicate a wiring issue.
• Oil Pressure Sensor- The oil pressure sensor itself is very likely to be the cause of P0522, but looking at the oil and wiring first is a smart move.

P0522 Diagnosis: Jeep Compass

This P0522 diagnosis order is written (like everything on the site) for the DIY guy who doesn’t have a lot of specialty tools. 

1. Check the Oil

The first thing that you should do is check the oil level.  If it’s full make sure that it looks healthy.  If it appears to be black or grimy, it may be interfering with the oil pressure sensor.  If the wrong oil viscosity was used it can also trigger P0522 even with a full reading on the dipstick.

2. Inspect the Wiring Harness

Next, you should inspect the wiring harness running from the oil pressure sensor to the PCM.  If it has any damaged wiring, that could be causing P0522.  Don’t forget to make sure that the harness is still plugged into the sending unit and undamaged.  

Wiring issues are one of the more common reasons that this code is thrown.  The wiring is close to the Compass’s exhaust and can get brittle over time.

3. Manually Check The Oil Pressure

Assuming that the oil level and wiring look fine, the next thing to do would be to manually check the oil pressure.  You can use a manual oil pressure gauge to see if it’s where it needs to be.  They are easy to use.  Here’s a great YouTube video that will show you exactly how to use this gauge to check.

If the oil pressure from the gauge reads ok, you’ll need to replace the oil pressure sending unit/sensor.  They’re cheap.  If there is low or no oil pressure, you’ll need to figure out why.

Conclusion:  P0522 Jeep Compass

It’s relatively straightforward diagnosing P0522.  Knowing the actual oil pressure level makes it a lot easier.  Feel free to leave a comment below if there is something that you would like to add and good luck fixing your Jeep Compass!
