PINPOINT TEST G531332p4 : THROTTLE POSITION (TP) SENSOR RANGE/PERFORMANCE, HIGH/LOW VOLTAGE

G531332t11 : CHECK THE TP SENSOR SENSING CIRCUIT TP1 FOR HIGH RESISTANCE
1. Key off.
2. Disconnect the ECM electrical connector, PI300.
3. Disconnect the TP sensor electrical connector, PI26.
4. Measure the resistance between:

ECM connector PI300, TP sensor connector PI26,
harness side harness side
Pin 65 Pin 06

- Is the resistance greater than 5 Ohms?

->YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G531332t12.
