Throttle Position (TP) Sensor
The throttle position (TP) sensor is a potentiometer mounted on the throttle body. The TP sensor detects the position of the throttle plate and sends this information to the powertrain control module (PCM). The TP sensor is used for shift scheduling, electronic pressure control and torque converter clutch (TCC) control.
NOTE:
Do not take any short cuts or assume that critical checks or adjustments have already been made.
Follow the procedures as written to avoid missing critical components or steps.
To properly diagnose a concern have the following publications available:
- Transmission Reference Manual.
- SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article.
- TSBs and OASIS Messages.
- Wiring Diagram.
These publications provide the information required when diagnosing transmission concerns.
Use the Diagnostic Flow Chart as a guide and follow the steps as indicated.
