Code P0951 Description
The P0951 code refers to a Auto Shift Manual Control Circuit Range/Performance issue. This code is set when the powertrain control module (PCM) detects that the voltage signal from the auto shift manual control circuit is outside of the expected range or performance parameters. The auto shift manual control circuit is responsible for controlling the shifting of the transmission in vehicles with automatic transmissions that also offer manual shifting capabilities. When this circuit is not functioning properly, it can lead to issues with shifting, potentially causing the transmission to shift erratically or not at all.
Common Causes of P0951
- Damaged wiring or connectors in the auto shift manual control circuit
- Malfunctioning auto shift manual control module
- Low transmission fluid levels
- Faulty transmission solenoid
- Mechanical issues within the transmission
Symptoms of P0951
- Erratic shifting behavior
- Difficulty shifting between gears
- Delayed or harsh shifting
- Transmission slipping
- Illumination of the check engine light
How to Fix P0951
- Begin by conducting a thorough inspection of the auto shift manual control circuit, checking for any damaged wiring or connectors. Repair or replace any damaged components as needed.
- Check the transmission fluid level and condition. Top off or replace the fluid if it is low or contaminated.
- Test the transmission solenoid for proper operation. Replace it if it is faulty.
- If the issue persists, perform a more in-depth diagnosis of the transmission itself, checking for any mechanical issues that may be causing the problem.
- Clear the diagnostic trouble codes from the PCM and test drive the vehicle to ensure that the issue has been resolved.
