Connections of the tilt lever position sensor
This diagnostic code is recorded when the ECM determines that the signal for the tilt lever position sensor has an abnormal pulse width.The sensor is a PWM sensor that operates at a frequency of approximately 500 hertz. The sensor has an operating duty cycle of 5% to 95%.The possible causes for this diagnostic code are listed:
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 these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 0353 FMI 08 is active before performing this procedure.Use a digital multimeter for the measurements in the procedure.System Response:The tilt function will not operate while the diagnostic code is active.Test Step 1. 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 contact 1 (wire 709-OR(Orange)) for the voltage supply.
Turn the key start switch and the disconnect switch to the ON position.
Measure the voltage from contact 1 (wire 709-OR(Orange)) to contact 2 (wire J764-BR(Brown)). 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 2. CHECK THE SIGNAL CIRCUIT OF THE SENSOR.
Turn the key start switch and the disconnect switch to the OFF position.
At the back of the harness connector for the sensor, remove the multimeter probe from contact 1 and insert the probe along the signal wire (contact 3).
At the back of the harness connector for the sensor, insert the multimeter probe along the ground wire (contact 2).
Turn the disconnect switch and the key start switch to the ON position.
Monitor the signal of the sensor with the digital multimeter.
Without disconnecting the sensor or the hardware that is associated with the sensor from the machine, take the sensor through the full operating range of the sensor. Expected Result:The
