P1114

Description
ECT SENSOR CIRCUIT INTERMITTENT LOW VOLTAGE

Engine Coolant Temperature (ECT) sensor is a thermistor that
varies resistance based on temperature. As temperature of sensor
increases, resistance decreases. High temperature will result in a low
signal voltage. DTC will set when PCM sees an ECT sensor voltage
intermittently less than 0.14 volt.

Symptoms
You likely won't notice any drivability problems.

Causes

  • ECT sensor intermittently indicates ECT greater than
    237F (114C).
  • ECT voltage intermittently less than 0.74 volt.
