Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Code P096, Torque Converter Overstress: Notes
This test checks for unusually large throttle position at low vehicle speed with the brake being applied. Primary purpose of Code P096 is to record snapshot data and alert driver that this condition could damage vehicle drivetrain or create an unsafe condition. Code P096 will set if such a driving condition exists.
Most occurrences of this code will be due to the application of brake and accelerator at the same time. TCC brake switch, transaxle range switch, VSS and TP sensor failures should be caught by other diagnostic codes. If any of the following checks fail, see appropriate code chart for diagnosis.
- Check operation of brake switch using TCC brake switch input test (PI71).
- Check operation of TP sensor by monitoring TPS degrees while moving throttle (Codes P021, P022 and P070).
- Check for correct MPH indication on instrument panel (Code P024).
- Check operation of transaxle range switch by monitoring AUTO status light while shifting in and out of Park/Neutral (Code P091).
