- Replace ECM
- Replace Tumble Generator Valve Position Sensor
- Repair harness between ECM and tumble generator valve position sensor
- Check harness for short circuit
When your vehicle’s check engine light comes on, it usually means there is a problem that needs to be addressed. One common issue that can cause this is the Subaru code P1088. This code indicates that there is an issue with the Tumble Generated Valve Position Sensor 1 Circuit Low. If this code is identified, it can lead to engine stalling, erroneous idling and poor driving performance. To determine the cause of the Subaru code P1088, it is important to use a scan tool to check the current data as well as the input signal for the ECM. Additionally, the harness between the ECM and the tumble generator valve position sensor connector should be checked for poor contact.
Causes and Solutions for Subaru Code P1088
| Cause | Solution |
|---|---|
| Using a scan tool, check current data | Replace ECM |
| Check input signal for ECM | Replace Tumble Generator Valve Position Sensor |
| Check harness between ECM and tumble generator valve position sensor connector | Repair harness between ECM and tumble generator valve position sensor |
| Check poor contact | Check harness for short circuit |
When the vehicle’s check engine light comes on, it is important to take it seriously as it typically means there is a problem that needs to be addressed. The Subaru code P1088 is an indication of an issue with the Tumble Generated Valve Position Sensor 1 Circuit Low. This code can lead to engine stalling, erroneous idling and poor driving performance. To diagnose the cause of the Subaru code P1088, a scan tool must be used to check the current data as well as the input signal for the ECM. In addition, the harness between the ECM and the tumble generator valve position sensor connector must be checked for poor contact. Knowing the causes and solutions of this code can help you effectively address the issue and get your vehicle back up and running.
Replace ECM
Replacing the ECM is one of the solutions to the Subaru code P1088. Using a scan tool, you can check the current data and input signal for the ECM. If the scan tool determines that the ECM is faulty or malfunctioning, then it is necessary to replace the ECM in order to address the issue.
Replace Tumble Generator Valve Position Sensor
The Tumble Generator Valve Position Sensor monitors the position of the valves and sends the signal to the ECM. If the ECM is receiving an incorrect signal due to a faulty Tumble Generator Valve Position Sensor, then it is necessary to replace the sensor in order to address the issue.
Repair Harness between ECM and Tumble Generator Valve Position Sensor
The harness between the ECM and the tumble generator valve position sensor needs to be checked for poor contact. If the harness is not functioning correctly, then it is necessary to repair the harness in order to address the issue.
Check Harness for Short Circuit
The harness between the ECM and the tumble generator valve position sensor needs to be checked for a short circuit. If the harness has a short circuit, then it is necessary to repair the harness in order to address the issue.
Conclusion
Subaru Code P1088 is an indication of an issue with the Tumble Generated Valve Position Sensor 1 Circuit Low. To effectively address this issue, it is important to use a scan tool to check the current data as well as the input signal for the ECM. Additionally, the harness between the ECM and the tumble generator valve position sensor connector must be checked for poor contact and a short circuit. Knowing the causes and solutions of this code can help you ensure that the issue is addressed and your vehicle is back up and running.
