DH10 - Check TP Circuit Continuity
- Key Off.
- TP sensor disconnected.
- Disconnect PCM. Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.
- Install breakout, leave PCM disconnected.
- Measure the resistance between TP circuit at the TP sensor vehicle harness connector and Test Pin 89 (TP SIG) at the breakout box.
- Is the resistance less than 5.0 ohms?
YES -- TP SIG harness circuit to PCM is OK. Go to DH11. DH11 - Check TP Circuit For Shorts to SIG RTN or PWR GND
NO -- SERVICE open in TP SIG harness circuit. REMOVE breakout box. RECONNECT all components. Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes
