THROTTLE POSITION (TP) SENSOR INSPECTION [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513)

BME014018910202

  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 or PCM terminal 89 voltage are out of specification, perform the "Circuit Open/Short Inspection".

Specification

  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 (harness-side) and PCM terminal 91
  - TP sensor terminal B (harness-side) and PCM terminal 89
  - TP sensor terminal C (harness-side) and PCM terminal 90

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the harness.
  - TP sensor terminal A (harness-side) and power supply
  - TP sensor terminal B (harness-side) and power supply
  - TP sensor terminal B (harness-side) and body ground
  - TP sensor terminal C (harness-side) and power supply
  - TP sensor terminal C (harness-side) and body ground
