The following conditions must be met before the Powertrain Control Module (PCM) can detect "Engine is Cold Too Long":
- Engine must have been running for at least 12 minutes
- After the 12-minute timer has timed out, the PCM must detect Vehicle Speed Sensor (VSS) readings of greater than 28 MPH for a total of eight minutes.
The Diagnostic Trouble Code (DTC) is stored if the Engine Coolant Temperature (ECT) sensor does not indicate that the temperature of the engine has exceeded 170° F. after all of the timers have timed out.
This malfunction could possibly be caused by any of the following:
- Extremely cold temperatures
- Coolant thermostat
- ECT sensor
- Related wiring or connectors (corrosion) PCM
