P1777 code can be about replacing a broken oxygen sensor can eventually lead to a busted catalytic
convertor which can cost upwards of $2,000. Taking your car into a shop will
cost you around $200 depending on the car. However, an oxygen sensor is easy
to replace on many cars and is usually detailed in the owner’s manual.
If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one.
Regardless of how you approach it, you should get this fixed right away.

P1777 Code Meaning :

P	1	7	7	7
OBD-II Diagnostic Powertrain (P) Trouble Code For Engine	Fuel And Air Metering	Fuel Rail Pressure Sensor Circuit Malfunction	Cylinder 10 Contribution/balance Fault	Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical

When you check car engine light came on code P1777 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However manufacturer may have a different definition for the P1777 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.

P1777 Fault Symptoms :

Check engine light comes on Engine stalling or misfiring Engine performance issues Car not starting

If one of these reasons for P1777 code is occuring now you should check P1777 repair processes. Now don’t ask yourself; What should you do with P1777 code ? The solution is here :

P1777 Possible Solution :

The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn’t working correctly, the car will run rough and the engine will be less efficient. In later car models, the car’s computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

Parts or components should not be replaced with reference to only a P1777 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.

Ошибки (коды ошибок) полученные от прибора, сканера требуют правильной интерпретации информации, дабы не тратить время и деньги на замену работающих элементов автомобиля.

Проблема зачастую кроется намного глубже чем кажется на первый взгляд. Это& вызвано теми обстоятельствами, что информационные сообщения содержат, как было выше сказано, косвенную информацию о нарушении работы системы.

Может быть полезным для решения вопроса по устранению неисправности у Suzuki Grand Vitara:

Возможные причины: Неисправный шаговый двигатель; Жгут шагового двигателя открыт или замкнут; Шаговый двигатель плохое электрическое соединение.

Шаговый двигатель изменяет шаг путем включения / выключения 4 катушек в соответствии с сигналом от модуля управления коробкой передач (TCM). В результате поток давления в линии к первичному шкиву изменяется, и отношение шкива регулируется.
