The FIAT Code P1037 indicates a cylinder 1 oil supply solenoid valve driver short to ground, an electronically controlled variable intake valve phase, and a lift system. When a vehicle is experiencing this code, it suggests that there is something wrong with the variable valve actuation solenoid, the powertrain control module (PCM), or the return circuit. As a result, a thorough diagnosis is needed to determine the exact cause and solution. This article will provide an overview of the possible causes and solutions for the FIAT Code P1037.
Causes and Solutions for FIAT Code P1037
| Cause | Solution |
|---|---|
| VARIABLE VALVE ACTUATOR SOLENOID SIGNAL CIRCUIT SHORTED TO GROUND | Check the wiring harness for any loose connections and inspect the solenoid for any signs of damage. |
| VARIABLE VALVE ACTUATOR SOLENOID RETURN CIRCUIT SHORTED TO GROUND | Replace the solenoid, and inspect the wiring harness and the PCM. |
| VARIABLE VALVE ACTUATOR SOLENOID | Replace the solenoid, and inspect the wiring harness and the PCM. |
| POWERTRAIN CONTROL MODULE (PCM) | Install a new PCM and reset the system. |
Variable Valve Actuator Solenoid Signal Circuit Shorted to Ground
When the FIAT Code P1037 is caused by a variable valve actuator solenoid signal circuit shorted to ground, inspecting the wiring harness for any loose connections and checking for any signs of damage on the solenoid. If the wiring harness is damaged or the solenoid is faulty, replacing them as soon as possible is important.
Variable Valve Actuator Solenoid Return Circuit Shorted to Ground
In the event that the FIAT Code P1037 is caused by a variable valve actuator solenoid return circuit shorted to ground, the solenoid should be replaced, and the wiring harness and PCM should be inspected. If any damage is found, they should be replaced as soon as possible.
Variable Valve Actuator Solenoid
If the FIAT Code P1037 is caused by a faulty variable valve actuator solenoid, the solenoid should be replaced, and the wiring harness and PCM should be inspected. If any damage is found, they should be replaced as soon as possible.
Powertrain Control Module (PCM)
If the FIAT Code P1037 is caused by a faulty Powertrain Control Module (PCM), the PCM should be replaced, and the system should be reset. It is essential to have a trained technician do this, as resetting the system incorrectly can cause further damage.
Conclusion
The FIAT Code P1037 can be caused by a number of issues related to the variable valve actuation solenoid, the powertrain control module (PCM), or the return circuit. To ensure the proper diagnosis and resolution of the issue, it is essential to have a trained technician inspect the vehicle and perform the necessary repairs. With the correct diagnosis and repairs, the FIAT Code P1037 can be fixed quickly and safely.
