Section 5.35
PID 174, FMI 4, Flash Code 24, Fuel Temperature Sensor Input Voltage Low
The Fuel Temperature Sensor input voltage is low due to a short to ground.
Section 5.35.1
Troubleshooting PID 174, FMI 4, FLASH CODE 24
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. |
- Check wire 472 (orange, fuel temperature) cavity R-3 in the Engine Sensor Harness (ESH) 30–pin connector for a short to ground (see Figure
"Engine Sensor Harness 30–pin Connector"
). If there is a short, replace or repair the wire(s).

- If the code is still active, go to step .
- If the code is no longer active, refer to "5.35.2 Verification" .
- Check pin B (fuel temperature) in the Fuel Temperature Sensor connector. If there is a short, replace or repair the wire(s).
- If the code is still active, Call Detroit Diesel Technical Service.
- If the code is no longer active, refer to "5.35.2 Verification" .
Section 5.35.2
Verification
Verify troubleshooting as follows:
- Check the DDR to see if PID 174, FMI 4, Flash Code 24 is still active.
- If the code is still active, go to step 2.
- If the code is not active, troubleshooting is complete.
- If the code is still active, call Detroit Diesel Technical Service.
