Charge Air Cooler Coolant Temperature Sensor A Circuit Range/Performance

Descripción

This code means the charge air cooler coolant temperature sensor is not providing a reading within its expected range or is performing erratically. The car's computer is getting unreliable temperature data for the charge air cooling system.

Pasos de reparación

1. 1 Check the coolant level in the charge air cooler system and top off if low.
2. 2 Inspect the charge air cooler coolant system for air pockets and bleed the system if necessary.
3. 3 Inspect the wiring and connector to the charge air cooler coolant temperature sensor for damage, corrosion, or loose connections.
4. 4 Test the charge air cooler coolant temperature sensor with a multimeter to verify it is reading within the correct resistance range for the current temperature.
5. 5 Replace the charge air cooler coolant temperature sensor if it is out of specification.
6. 6 Repair or replace any damaged wiring or connectors in the sensor circuit.
7. 7 Have the engine control module (ECM) tested and reprogrammed or replaced if all other components test normal.
