Mazda 6 Service Manual: Throttle position (tp) sensor inspection

Mazda 6 Service Manual / Fuel and emission control systems / Control system / Throttle position (tp) sensor inspection

Note

Perform the following inspection only when directed.

Resistance Inspection

1. Perform the following test only when directed.

If as specified but TP PID value is out of specification, inspect resistance of TP sensor.
If not as specified, inspect the following:

- Accelerator cable free play (See ACCELERATOR CABLE INSPECTION/ADJUSTMENT.)

2. Disconnect the TP sensor connector.

3. Verify that the resistance between TP sensor terminals A and B changes smoothly while opened and closed the throttle valve slowly.

If not verified, replace 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 TP PID value is 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.)

2. Inspect the following wiring harnesses 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 2H (harness-side)

- TP sensor terminal B (harness-side) and PCM terminal 2A (harness-side)

- TP sensor terminal C (harness-side) and PCM terminal 2K (harness-side)

Short circuit

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

- TP sensor terminal C (harness-side) and power supply

- TP sensor terminal C (harness-side) and body GND

- TP sensor terminal B (harness-side) and power supply

- TP sensor terminal B (harness-side) and body GND

- TP sensor terminal A (harness-side) and power supply
