1. 1

   Visually inspect the sensor mounting on the exhaust pipe for looseness and ensure it is properly tightened.

2. 2

   Inspect the 2-pin electrical connector at the sensor for corrosion, pushed-out pins, or moisture.

3. 3

   Use a multimeter to check the wiring harness between the sensor and the ECU for a broken wire (open circuit) or a short to the battery.

4. 4

   Test the sensor resistance; if the wiring is intact, the sensor itself has likely failed internally (open circuit) and requires replacement.

1. 1

   Locate the Sensor

   Find the DOC inlet temperature sensor. It is threaded into the exhaust pipe as close as possible to the inlet of the Diesel Oxidation Catalyst (DOC).

2. 2

   Disconnect Power

   Turn off the machine and disconnect the battery to prevent any electrical spikes.

3. 3

   Disconnect the Sensor

   Unplug the 2-pin electrical connector from the sensor harness.

4. 4

   Remove the Sensor

   Carefully unscrew the temperature sensor from the exhaust pipe. (Note: Exhaust sensors can seize due to high heat; penetrating oil may be required before removal).

5. 5

   Install the New Sensor

   Thread the new OEM sensor into the exhaust inlet and tighten it securely.

6. 6

   Reconnect

   Plug the 2-pin connector back into the engine wiring harness.

7. 7

   Clear Codes

   Reconnect the battery, turn the key on, and use a diagnostic tool to clear the E4360.03 fault code from the ECU. Run the engine to verify the code does not return.
