Massey Ferguson E105 – Engine Control Unit (ECU) / EEM: Intake Manifold Temperature

The intake manifold temperature has exceeded the warning limit or the sensor signal is outside the normal operating range.

1. 1

   Check the cooling system radiators for blockages, dirt, or damage

2. 2

   Inspect the condition of the vent lattices/grilles to ensure fresh air can flow freely into the engine bay

3. 3

   Inspect the wiring harness running from the intake manifold temperature sensor (or combined boost pressure sensor) to the Engine ECU for shorts to ground, shorts to voltage, or open circuits

4. 4

   Check the ECU connector and the sensor connector for corrosion, bent pins, or loose connections

1. 1

   Clean the Cooling System

   Blow out the radiators and vent lattices with compressed air to ensure the high intake temperature isn't simply being caused by restricted airflow.

2. 2

   Test the Sensor

   If airflow is adequate, locate the intake manifold temperature sensor (often located on the intake manifold and combined with the boost pressure sensor). Test the sensor's resistance; if the resistance does not change smoothly with temperature variations, the sensor is faulty.

3. 3

   Replace the Sensor

   Disconnect the wiring harness from the sensor. Unbolt/unscrew the faulty sensor from the intake manifold and install the replacement part.

4. 4

   Clear the Code

   Turn on the tractor and use a diagnostic scan tool or the tractor's dashboard interface to delete the error code from the control unit.

5. 5

   Reactivate Systems

   If the tractor locked out any hydraulic valves or engine functions due to the code, stop and re-run the engine to reactivate them.
