The Nissan Code P1754 indicates a problem with the A/T I/C Solenoid Valve Circuit. When the engine is started and the engine is running for over 30 seconds, the PCM will detect an unexpected voltage condition during the operation of the A/T I/C Solenoid valve circuit. In this case, the cause of the problem can be attributed to a number of elements, including the I/C solenoid connector, I/C solenoid control circuit, I/C solenoid, TCM, or even the PCM. Therefore, it is important to have an understanding of the possible causes and solutions for the Nissan Code P1754 to repair the vehicle correctly.
Causes and Solutions of Nissan Code P1754
| Cause | Solution |
|---|---|
| I/C solenoid connector is damaged or has failed | Replace the I/C solenoid connector with a new one |
| I/C solenoid control circuit is open or shorted to ground | Check and repair the I/C solenoid control circuit |
| I/C solenoid is damaged or has failed | Replace the I/C solenoid with a new one |
| TCM or PCM has failed | Replace the TCM or PCM with a new one |
When a Nissan vehicle is experiencing an issue with the A/T I/C Solenoid Valve Circuit, one of the most common diagnostic codes that will be triggered is Nissan Code P1754. In this situation, the PCM has detected an unexpected voltage condition during the operation of the A/T I/C Solenoid valve circuit, likely caused by a failed or damaged I/C solenoid, I/C solenoid connector, I/C solenoid control circuit, TCM, or PCM. It is important to troubleshoot the issue correctly and to identify the cause of the problem in order to repair the vehicle properly. To assist with this, the following table provides a list of the possible causes and associated solutions of the Nissan Code P1754.
I/C Solenoid Connector
When the I/C solenoid connector is damaged or has failed, this can often cause the Nissan Code P1754 to be triggered. To address this issue, the I/C solenoid connector should be replaced with a new one.
I/C Solenoid Control Circuit
If the I/C solenoid control circuit is open or is shorted to ground, this can also cause the Nissan Code P1754 to be triggered. To address this issue, the I/C solenoid control circuit should be checked and repaired.
I/C Solenoid
When the I/C solenoid is damaged or has failed, this can also cause the Nissan Code P1754 to be triggered. To address this issue, the I/C solenoid should be replaced with a new one.
TCM or PCM
If the TCM or PCM has failed, this can also cause the Nissan Code P1754 to be triggered. To address this issue, the TCM or PCM should be replaced with a new one.
Conclusion
Nissan Code P1754 is a diagnostic code that is triggered when the PCM has detected an unexpected voltage condition during the operation of the A/T I/C Solenoid valve circuit. The cause of this code can be attributed to a number of elements including the I/C solenoid connector, I/C solenoid control circuit, I/C solenoid, TCM, or even the PCM. By understanding the possible causes and solutions of Nissan Code P1754, it is possible to repair the vehicle correctly and address the issue quickly.
