Inspection With Circuit Tester

INSPECTION

1. Check G sensor.
1) Turn ignition switch to OFF.
2) Remove G sensor from vehicle.





3) Connect connector to G sensor.
4) Turn ignition switch to ON.
5) Measure voltage between G sensor connector terminals.
Connector & terminal: (P9) No.2 (+) - No.1(-).
CHECK: Is the voltage 2.3 ± 0.2 Volts when G sensor is horizontal?
YES: Go to step 2.
NO: Replace G sensor.





2. Check G sensor (forwards).
Measure voltage between G sensor connector terminals.
Connector & terminal: (P9) No.2 (+) - No.1 (-).
CHECK: Is the voltage 3.9 ± 0.2 Volts when G sensor is inclined forwards to 90�?
YES: Go to step 3.
NO: Replace G sensor.





3. Check G sensor (backwards).
Measure voltage between G sensor connector terminals.
Connector & terminal: (P9) No.2 (+) - No.1 (-).
CHECK: Is the voltage 0.7 ± 0.2 Volts when G sensor is inclined backwards to 90�?
YES: G sensor is normal.
NO: Replace G sensor.
