Gear Sensor/Switch: Testing and Inspection
NEUTRAL SWITCH INSPECTIONNOTE: Perform the following inspection only when directed.
Continuity Inspection
1. Disconnect the negative battery cable.
2. Remove the neutral switch. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [G35M-R].)
3. Inspect for continuity between the neutral switch terminals using an ohmmeter.
- If the neutral switch is normal, but PID value is out of specification, perform the "Circuit Open/Short Inspection".
- If not as specified, replace the neutral switch.
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION.)
2. Inspect the following harnesses for open or short circuit. (Continuity check)
Open circuit
- If there is no continuity, there is an open circuit. Repair or replace the harness.
- Neutral switch terminal B and PCM terminal 1W
- Neutral switch terminal A and body GND
Short circuit
- If there is no continuity, there is a short circuit. Repair or replace the harness.
- Neutral switch terminal B and body GND
