Transmission Fluid Cooler Control Circuit/Open
The P2753 code indicates that the Powertrain Control Module (PCM) has detected an open circuit in the transmission fluid cooler control circuit. This circuit typically controls a solenoid or valve that regulates the flow of transmission fluid to the cooler. An open circuit means there is a break in the electrical path, preventing proper operation. This can lead to inadequate cooling of the transmission fluid, potentially causing overheating and transmission damage.
01. Most Common Causes
- Faulty transmission fluid cooler control solenoid
- Open or shorted wiring in the control circuit
- Corroded or damaged connector
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Transmission overheating
- Poor transmission performance or slipping
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Visually inspect the wiring and connectors for damage, corrosion, or loose connections.
Step 3: Test the transmission fluid cooler control solenoid resistance with a multimeter and compare to specifications.
Step 4: Check for voltage and ground at the solenoid connector with the ignition on.
Step 5: If wiring and solenoid are okay, test the PCM output circuit for continuity.
