Troubleshooting Flash Code 81, PID 98/FMI 3
The EOL Sensor is part of the Maintenance Alert System (MAS). Troubleshoot p 98/3 using the following procedures.
Multiple Code Check
Perform the following steps to check for multiple codes:
- Turn ignition ON and plug in your diagnostic tool.
- Read active codes. Turn ignition OFF.
- If code 98/3 displays with code s 232/0, troubleshoot s 232/0 first.
- If code 98/3 displays, refer to "73.4.2 Check Connectors and Sensor" .
Check Connectors and Sensor
Perform the following steps to check the connectors:
- Unplug the OLS/EOL Sensor.
- Turn the ignition ON and read the codes.
- Replace the EOL Sensor. Verify the repair. Refer to "18.104.22.168 Verify Repairs" .
Check for Short and Open
Perform the following steps to check for short and open:
- Measure resistance between pin B and pin C of the EOL Sensor. See Figure "Oil Level Sensor" .
- Unplug the Engine Harness connector.
- Insert a jumper harness between the pins A and B of the EOL Sensor connector. Measure resistance between cavity E–15 and E–21. See Figure
"Oil Level Sensor"
- If reading is greater than 10 Ω, cavity E–15 is open. Repair the open or replace the harness; verify the repair. See Figure "Oil Level Sensor" . Refer to "22.214.171.124 Verify Repairs" .
- If the reading is less than 10 Ω, contact the Detroit Diesel Customer Support Center (313–592–5800) or try a test ECM/ECU.
