DIAGNOSTIC PROCEDURES:
DTC: Diagnostic Trouble Code
PCM: Powertrain Control Module
ECT: Engine Coolant Temperature
DIAGNOSTIC HINTS:
1.
If the fast idle speed is not high enough or if the engine produces dark smoke during engine warm-up operation, a malfunctioning engine coolant
temperature sensor might be the cause.
2.
If the thermostat opening state is abnormal and causes overcooling, the Diagnostic Code (DTC) for the engine coolant temperature sensor can be
set.
3.
The Malfunction Indicator Lamp (MIL) is on or the DTC is set under the following conditions:
a.
When the engine coolant temperature is detected by the sensor as below -40°C or above 120°C.
b.
If the engine coolant temperature does not increase at least 5°C, even though 130 seconds or more have elapsed after starting the engine.
