P2753: Transmission Fluid Cooler Control Circuit/Open
The P2753 code indicates an open circuit in the transmission fluid cooler control circuit. This circuit typically controls a valve or pump that regulates transmission fluid temperature. An open circuit means there is a break in the electrical path, preventing proper operation. This can lead to transmission overheating and potential damage.
1. Most Common Causes
- Faulty transmission fluid cooler control solenoid
- Open or shorted wiring in the control circuit
- Corroded or damaged connector
- Failed transmission control module (TCM)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Transmission overheating
- Erratic shifting or slipping
- Reduced fuel economy
3. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Visually inspect the transmission fluid cooler control solenoid and its wiring for damage, corrosion, or loose connections.
Step 3: Use a multimeter to test the solenoid resistance and check for continuity in the circuit.
Step 4: If wiring and solenoid are okay, test the TCM output signal to the solenoid.
