Step
1 1. Turn the key off.
2. Disconnect coil integrated module connector.
3. Measure the FL speed sensor resistance between coil
integrated module connector (C-4) terminals 2 and 10.
Is the resistance between 2.0k and 2.8k ohms?
2 Is there play sensor/sensor rotor?
3 Measure the FL speed sensor resistance at the sensor connector.
Is the resistance between 2.0k and 2.8k ohms?
4 Damage and powered iron sticking to sensor/sensor ring?
5 Is sensor output normal? (Chart C-1-1 or TC-1)
6 1. Reconnect all components, ensure all components are
