The code is typically the engine coolant outlet temperature circuit failed low.
Repair the short to ground between pin 2 of the Engine Coolant Outlet Sensor harness connector and pin 110 of the MCM 120–pin connector. Refer to "27.2.1 Verify Repairs" .
Verify repairs as follows:
- Turn ignition OFF.
- Reconnect any electrical connections that were disconnected to perform the diagnosis.
- Clear codes with DDDL 7.0 or latest version.
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.
- Start and bring engine up to operating temperature (over 140°F/60°C).
- Verify operation is satisfactory and no warning lamps illuminate. If warning lamps illuminate, troubleshoot the codes. If assistance is required, call the Detroit Diesel Customer Support Center at 313–592–5800.
