THROTTLE POSITION (TP) SENSOR INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed))

Note

• Perform the following test only when directed.

Resistance Inspection

1. Verify that the throttle valve is at CTP.

2. Inspect accelerator cable free play. (See ACCELERATOR CABLE INSPECTION [AJ].)

3. Verify that resistance between TP sensor terminals A and B changes smoothly while throttle valve is gradually opened.

• If normal, go to next step.

• If not normal, replace the TP sensor.

4. Measure the resistance between TP sensor terminals A and C using an ohmmeter.

• If not as specified, replace the TP sensor.

• If as specified, but PID value is out of specification, perform the "Circuit Open/Short Inspection".

3.2-4.8 kilohms

Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [AJ].)

2. Check the following wiring harness for open or short (Continuity check).

Open circuit

• If there is no continuity, the circuit is open. Repair or replace the harness.

- TP sensor terminal A and PCM terminal 20

- TP sensor terminal B and PCM terminal 40

- TP sensor terminal C and PCM terminal 33

Short circuit

• If there is continuity, the circuit is shorted. Repair or replace the harness.

- TP sensor terminal A and power supply

- TP sensor terminal B and power supply

- TP sensor terminal B and body ground

- TP sensor terminal C and power supply

- TP sensor terminal C and body ground
