Connections of the Transmission Output Speed Sensor 1
This diagnostic code is associated with the Transmission Output Speed Sensor 1. The FMI 08 means that the ECM has determined that the signal frequency or the signal pulse width is not within the expected range.There are two speed sensors for transmission output speed: the transmission output speed sensor 1 and the transmission output speed sensor 2. The Transmission ECM determines the existence of this diagnostic code by comparing the signals from sensor 1 and from sensor 2. This diagnostic code is recorded when one of the sensors indicates a valid speed signal that is above the minimum and the other sensor signal that is below the dropout.Note: Failures of the transmission output speed sensor will be recorded only while the machine is moving.Possible causes of this diagnostic code are listed:
There is a malfunction or misalignment of the sensor.System Response:The machine response is listed:
Transmission shifting may be harsh.
Shift hesitation during directional shifts.Test Step 1. CHECK THE RESISTANCE OF THE SENSOR.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness from the speed sensor.
Measure the resistance between contacts 1 and 2 of the connector for the speed sensor. Expected Result:The resistance should be between 800 and 1800 ohms.Results:
YES - The speed sensor has not failed. Proceed to Test Step 2.
NO - The speed sensor failed.Repair: Replace the speed sensor.STOPTest Step 2. CHECK THE SIGNAL CIRCUIT FOR AN OPEN IN THE MACHINE HARNESS.
The key start switch and the disconnect switch remain in the OFF position.
The key start switch and the disconnect switch remain in the OFF position.
Disconnect machine harness connectors J1 and J2 from the power train ECM.
Measure the resistance from the sensor signal J1-2 wire (E900-WH(White)) to the return contact J1-3 wire (E901-GN(Green)) of the machine harness. Expected Result:There should be continuity (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 (wire E900-WH(White) or wire E901-GN(Green)).Repair: Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE SIGNAL FOR A SHORT.
Remove the jumper between contact 1 and contact 2 for the machine harness connector for the speed sensor.
Reconnect the speed sensor to the machine harness.
At the J1 and J2 harness connectors, measure the resistance between J2-2 and all possible sources of positive voltage and ground.
Repeat the previous Test Step for contact J2-3. Expected Result:Each resistance should be greater than 5000 Ohms.Results:
YES - The machine harness is correct. Proceed to Test Step 4.
NO - There is a short in the machine harness. The short is between the signal circuit (wire E900-WH(White) or wire E901-GN(Green)) and the circuit with low resistance.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 4. CHECK IF THE DIAGNOSTIC CODE REMAINS.
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, corrosion, or chafing.
