P0695: Fan 3 Control Circuit Low
The P0695 code indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the control circuit for the cooling fan 3 relay. This typically means the circuit voltage is below the expected threshold, often due to a short to ground, faulty relay, damaged wiring, or a failed fan motor. The PCM monitors the fan control circuit for proper voltage and current; when it senses a low signal, it sets this code.
01. Most Common Causes
- Faulty cooling fan 3 relay
- Short to ground in fan 3 control circuit
- Damaged wiring or connector
- Failed cooling fan 3 motor
- Faulty PCM (rare)
02. Symptoms You Will Notice
- Engine overheating
- Check Engine Light illuminated
- Cooling fan 3 not operating
- Reduced air conditioning performance
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to confirm P0695 and check for related codes.
Step 2: Visually inspect the fan 3 relay, wiring, and connector for damage or corrosion.
Step 3: Test the fan 3 relay and control circuit voltage with a multimeter.
Step 4: Check for continuity to ground in the control circuit to identify a short.
Step 5: If circuit is intact, test fan 3 motor operation by applying direct power.
