Series 50G/60G Troubleshooting – Section 5.16 PID 100, FMI 4, Flash Code 36, Oil Pressure Sensor Input Voltage Low

Section 5.16
PID 100, FMI 4, Flash Code 36, Oil Pressure Sensor Input Voltage Low

The Oil Pressure Sensor Input Voltage is low due to a short or an open wire.‪

Section 5.16.1
Troubleshooting PID 100, FMI 4, Flash Code 36

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 in the Engine Sensor Harness (ESH) 30–pin connector for a short to ground (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, go to step .
   2. If the code is not active, refer to "5.16.2 Verification" .
2. Check wire 530 (brown, oil pressure) cavity P–2 in the ESH 30–pin connector to see if it is open (see Figure "Engine Sensor Harness 30–pin Connector" ). Also check pin B (oil pressure) in the Oil Pressure Sensor connector. Repair or replace any open wire(s).
   1. If the code is still active, call Detroit Diesel Technical Service.
   2. If the code is not active, refer to "5.16.2 Verification" .

Section 5.16.2
Verification

Verify troubleshooting as follows: ‪

1. Check the DDR to see if PID 100, FMI 4, Flash Code 36 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.
