Massey Ferguson 102.14 – Engine ECU: Intake Boost Pressure Sensor Signal Erratic (ECU)

The engine control module is receiving a fluctuating, unstable, or implausible voltage signal from the intake boost pressure sensor (also known as a MAP sensor). This can cause the engine to degrade power levels or shut down depending on the severity of the erratic readings.

1. 1

   Verify the Code: Enter the tractor's diagnostic mode via the control panel to confirm 000102.14 is currently active.

2. 2

   Inspect the Wiring Harness: Check the 3-pin or 4-pin electrical connector at the boost pressure sensor for corrosion, moisture, or loose pins. Trace the wiring back to the Engine ECU to check for chafing or shorts.

3. 3

   Test Sensor Voltage: Use a multimeter to verify the sensor is receiving a steady 5.0V reference supply voltage from the ECU.

4. 4

   Check for Intake Leaks/Restrictions: Inspect the intake manifold for physical damage, cracks, or loose clamps. A severely clogged air filter or a physical intake leak can cause actual erratic pressure fluctuations inside the manifold.
