MID 027 CID 0672 FMI 08Conditions Which Generate This Code:
Illustration 1 g06322831
Connections of the torque converter output speed sensor
This diagnostic code is associated with the torque converter output speed sensor. The FMI 08 means that the ECM has determined that the signal frequency or the signal pulse width is not within the expected range.The possible causes of this diagnostic code are listed below:
The sensor has failed.
Intermittent connections or poor connections
Mechanical devices are loose.
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 CID 0672 FMI 08 is active before performing this procedure. The engine must be running in order for the diagnostic code to be active.Note: Use a digital multimeter for the measurements in this procedure.Test Step 1. INSPECT THE HARNESS CONNECTIONS.Reference: Follow the steps given in Testing and Adjusting, "Electrical Connector - Inspect" for inspecting the harness connections.Expected Result:The machine harness connectors are tight and free of corrosion.Results:
OK - The machine harness connectors are tight and free of corrosion. Proceed to test Step 2.
NOT OK - The machine harness connectors are in need of repair.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK THE CIRCUIT FOR AN OPEN.
Turn the disconnect switch and the key start switch to the OFF position.
Disconnect the machine harness from the sensor.
At the machine harness connector for the sensor, install a jumper wire between contact 1 and contact 2 of the harness for the sensor.
Disconnect the machine harness connector J1 from the ECM.
At the J1 machine harness connectors for the ECM, measure the resistance from contact J1-8 for the sensor to J1-9.Expected Result:There should be less than 5.0 ohms resistance.Results:
YES - The machine harness is correct. Proceed to Test Step 3.
NO - There is an open circuit in the machine harness. The open circuit is in the wire (L910-PK(Pink)) or in the wire (L911-YL(Yellow)) of the machine harness.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE SENSOR FOR AN OPEN
The disconnect switch and the key start switch remain in the OFF position.
Remove the jumper wire that was used in the previous Test Step.
Remove the sensor from the machine harness. Insert a multimeter probe in contact 1 and contact 2 of the sensor.
Measure the resistance of the sensor.Expected Result:The resistance should be between 1000 and 1200 ohms.Results:
YES - The resistance is between 1000 and 1200 ohms. The sensor is correct. Proceed to Test Step 4.
NO - The resistance is not between 1000 and 1200 ohms. The sensor has failed.Repair: Replace the sensor.STOPTest Step 4. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE.
Inspect the harness connectors. Clean the contacts of the harness connectors and check the wires for damage to the insulation that is caused by excessive heat, battery acid, or chafing.
Perform a 45 N (10 lb) pull test on each of the wires that are associated
