Schematic of the Position Sensor (Torque Converter Impeller Clutch)
This diagnostic code is associated with the Position Sensor (Torque Converter Impeller Clutch). The FMI 00 means that the ECM has determined that the signal of the sensor is above the normal range. The possible causes of this diagnostic code are listed below:
The sensor has failed.
The signal circuit of the sensor is shorted to the + battery circuit.
The sensor needs to be calibrated.
The ECM has failed. This is unlikely.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:When this diagnostic code occurs, the modulation for the torque converter impeller clutch may not function. The lockup clutch may not function.Test Step 1. INSPECT THE SENSOR
Perform a visual inspection of the sensor, the wiring for the sensor and the hardware that is associated with the sensor. Expected Result:There is no apparent damage to the sensor, the wiring for the sensor or the hardware that is associated with the sensor.Results:
OK - There is no apparent damage to the sensor, the wiring for the sensor or the hardware that is associated with the sensor. Proceed to Test Step 2.
NOT OK - There is apparent damage to the sensor, the wiring for the sensor or the hardware that is associated with the sensor. Repair: Replace the damaged part.Proceed to Test Step 8.Test Step 2. CHECK FOR POWER AT THE SENSOR
Do not disconnect the harness connector from the sensor.
