Condenser Fan Always On

CONDENSER FAN ALWAYS ON

CIRCUIT DESCRIPTION
The A/C condenser fan relay coil receives ignition voltage through the DEF fuse and the relay switch receives battery voltage through the HTR fuse. The powertrain control module (PCM) energizes and de-energizes the relay through the condenser fan relay control circuit. The PCM initiates condenser fan operation in response to an A/C system request, to an engine overheating condition, or to an engine coolant temperature (ECT) sensor malfunction.

DIAGNOSTIC AIDS
The PCM initiates condenser fan operation when any one of the following conditions are met:
- The engine coolant temperature (ECT) is 113°C (235°F) or higher. Connect a scan tool in order to determine ECT. Refer to Symptoms - Cooling System in Cooling System. Symptom Related Diagnostic Procedures
- The PCM detects an ECT sensor malfunction. Refer to the following in Computers and Control Systems 2.0 L:
- DTC P0116
- DTC P0117
- DTC P0118
- Refer to the following in Computers and Control Systems 2.5 L:
- DTC P0116
- DTC P0117
- DTC P0118
- The A/C system is operating.
