   The wiring and connections to the Low Fuel Pressure Supply Sensor

1. 1

   Measure the voltage on the sensor supply circuit

   Use a multimeter to check the voltage on the sensor supply circuit. Ensure it is within the expected range as specified in the service manual.

2. 2

   Inspect the wiring and connections

   Check for any damage, corrosion, or loose connections in the wiring and connectors for the Engine Oil Pressure Sensor, Low Fuel Pressure Supply Sensor, and Exhaust Throttle Position Sensor (ECU).

3. 3

   Test the affected component

   If the voltage is out of range, test the affected component to determine if it is causing the high voltage condition.
