THROTTLE POSITION (TP) SENSOR INSPECTION [L3 Turbo]

Note

• Perform the following inspection only when directed.

Voltage Inspection

1. Verify that no DTC related to APP sensor has been detected.

• If any DTCs related to APP sensor have been detected, perform the DTC inspection.

(See DTC TABLE [L3 Turbo].)

2. Start the engine and warm it up (ECT: more than 80°C {176 °F}).

3. Turn the ignition switch to the ON position (Engine off).

4. Verify that the PCM terminal 3J and 3M change smoothly while throttle valve is gradually opened.

• If as verified, go to next step.

• If not as verified, perform the "Circuit Open/Short Inspection".

- If there is no open or short circuit, replace the throttle body.

5. Verify that the PCM terminal 3J and 3M voltages are as shown in the following table.

• If voltage is not as following table, perform the "Circuit Open/Short Inspection".

- If there is no open or short circuit, replace the throttle body.

TP sensor output voltage

Condition	PCM terminal 3M (TP sensor No.1)	PCM terminal 3J (TP sensor No.2)
Ignition switch ON: APP is released	Approx. 0.85 V	Approx. 4.11 V
Idle (after warm up)	Gradually depress the accelerator pedal while verifying that the voltage changes.

Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)

2. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)

Open circuit

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

- Throttle body terminal A and PCM terminal 3M

- Throttle body terminal B and PCM terminal 3P

- Throttle body terminal C and PCM terminal 3J

- Throttle body terminal D and PCM terminal 3Q

Short circuit

• If there is continuity, there is a short circuit. Repair or replace the wiring harness.

- Throttle body terminal A and power supply

- Throttle body terminal A and body ground

- Throttle body terminal B and power supply

- Throttle body terminal B and body ground

- Throttle body terminal C and power supply

- Throttle body terminal C and body ground

- Throttle body terminal D and power supply
