Section 5.15 PID 100, FMI 3, Flash Code 35, Oil Pressure Sensor Input Voltage High

Section 5.15
PID 100, FMI 3, Flash Code 35, Oil Pressure Sensor Input Voltage High

The Oil Pressure Sensor input voltage is high due to a short.‪

Section 5.15.1
Troubleshooting PID 100, FMI 3, Flash Code 35

Troubleshoot as follows:‪

NOTICE:

To avoid damage to the harness and connectors when disconnecting harness connectors, ensure the pulling force is applied to the connectors and not to the wires extending from the connectors.‪

  1. Check wire 530 (brown, oil pressure) cavity P–2 for a short to wire 416 (gray, sensor supply, 5VDC) cavity W-1 in the Engine Sensor Harness (ESH) 30–pin connector (see Figure "Engine Sensor Harness 30–pin Connector" ). Also check pin B (oil pressure) in the Oil Pressure Sensor connector and pin C (sensor supply +5VDC) in the Fuel Pressure Sensor connector. If there is a short, repair or replace the wire(s), pins, and sockets.

    1. If the code is still active, go to step .
    2. If the code is on longer active, refer to "5.15.2 Verification"
  2. Check wire 530 (brown, oil pressure) cavity P–2 in the ESH 30–pin connector for a short to +12V/+24V (see Figure "Engine Sensor Harness 30–pin Connector" ). Also check pin B (oil pressure) in the Oil Pressure Sensor connector. If there is a short, repair or replace the wire(s), pins, and sockets.
    1. If the code is still active, call Detroit Diesel Technical Service.
    2. If the code is on longer active, refer to "5.15.2 Verification"

Section 5.15.2
Verification

Verify troubleshooting as follows: ‪

  1. Check the DDR to see if PID 100, FMI 3, Flash Code 35 is still active.
    1. If the code is still active, go to step 2.
    2. If the code is not active, troubleshooting is complete.
  2. If the code is still active, call Detroit Diesel Technical Service.
