Conditions Which Generate This Code:
Illustration 1 g01362188
Connections of the shift lever position sensorThis diagnostic code is associated with the shift lever position sensor. The FMI 0 means that the ECM has determined that the signal of the sensor is above the normal range.The output frequency of the position sensor is approximately 500 hertz. The value of the sensor's duty cycle is approximately 50% in the neutral position. The duty cycle of the signal increases as the lever is moved from the neutral position to the forward position. The value of the sensor's duty cycle is approximately 80% 10% in the forward position. The duty cycle of the signal decreases as the lever is moved from the neutral position to the reverse position. The value of the sensor's duty cycle is approximately 20% 10% in the reverse position. 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. Ensure that the diagnostic code of SPN 525 FMI 0 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.System Response:The transmission will be placed in NEUTRAL until the diagnostic code is cleared.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.
At the back of the harness connector for the sensor, insert a multimeter probe along the voltage supply wire (contact 1).
Turn the key start switch and the disconnect switch to the ON position.
Measure the voltage from contact 1 to frame ground.Expected Result:The voltage is 10 DCV.Results:
OK - The voltage is 10 DCV. Proceed to Test Step 3.
NOT OK - The voltage is not 10 DCV. The circuit is open. Repair: Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK FOR PROPER GROUND AT THE SENSOR.
The machine harness remains connected to the sensor.
Turn the key start switch and the disconnect switch to the OFF position.
Remove the multimeter probe from the voltage supply wire (contact 1).
At the back of the harness connector for the sensor, insert a multimeter probe along the ground wire (contact
