| DTC P1894: | Problem in CVT Speed Change Control Valve Circuit |
NOTE: Record all freeze data before you troubleshoot.
| 1. | Disconnect CVT speed change control valve connector. |
| 2. | Measure the resistance between connector terminals at the control valve connector.
Is the resistance 3.8-6.8 W? YES — Go to 3. NO — Faulty the CVT speed change control valve, replace the control valve body.n |
| 3. | Disconnect the battery negative terminal. |
| 4. | Disconnect PCM connectors B (24P) and C (22P). |
| 5. | Check for continuity between PCM connector terminal B24 and body ground, and between terminal C16 and body ground.
Are there continuity? YES — Repair short to ground in the wire between PCM connector terminal B24 and the CVT speed change control valve connector, and between terminal C16 and the CVT speed change control valve connector.n NO — Go to 6. |
| 6. | Reconnect CVT speed change control valve connector. |
| 7. | Measure the resistance between PCM connector terminals B24 and C16.
Is the resistance 3.8-6.8 W? YES — Check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.n NO — Repair loose terminal or open in the wires between PCM connector terminals B24 and C16, and the CVT speed change control valve connector.n |
| DTC P1894: | Problem in CVT Drive Pully Pressure Control Valve Circuit |
NOTE: Record all freeze data and review General Troubleshooting Information before you troubleshoot.
| 1. | Disconnect CVT drive pully pressure control valve connector. |
| 2. | Measure the resistance between connector terminals at the control valve connector.
Is the resistance 3.8-6.8 W? YES — Go to 3. NO — Faulty the CVT drive pully pressure control valve, replace the control valve body.n |
| 3. | Disconnect PCM connectors B (24P) and C (22P). |
| 4. | Check for continuity between PCM connector terminal B24 and body ground, and between terminal C16 and body ground.
Is there continuity? YES — Repair short to ground in the wire between PCM connector terminal B24 and the CVT drive pully pressure control valve connector, and between terminal C16 and the CVT drive pully pressure control valve connector.n NO — Go to 5. |
| 5. | Reconnect CVT drive pully pressure control valve connector. |
| 6. | Measure the resistance between PCM connector terminals B24 and C16.
Is the resistance 3.8-6.8 W? YES — Update the PCM if it does not have the latest software, or subsutitute a known-good PCM, then recheck. If the symptom/ indication goes away with a known-good PCM, replace the original PCM.n NO — Repair loose terminal or open in the wires between PCM connector terminals B24 and C16, and the CVT drive pully pressure control valve connector.n |

P1894 HONDA — Цепь регулирующего клапана изменения скорости CVT
P1894 HONDA Возможные причины
- Неисправен корпус клапана управления коробкой передач
- Клапан управления коробкой передач Жгут проводов кузова открыт или замкнут
- Неисправность электрической цепи в корпусе клапана управления коробкой передач
Как мне исправить код P1894 HONDA
Проверьте «Возможные причины», перечисленные выше. Визуально осмотрите соответствующий жгут проводов и разъемы. Проверьте, не повреждены ли компоненты, и проверьте, не сломаны ли, изогнуты ли, вытолкнуты или разъедены контакты разъема.
