P2612
A/C Refrigerant Distribution Valve Control Circuit Low
- Severity
- Low
- Driving
- No driving restriction
The air conditioning refrigerant distribution valve circuit is reading low - typically shorted to earth or an open circuit. The module cannot direct refrigerant between the evaporators.
Possible causes
- CommonFailed distribution valve solenoid
- CommonCorroded connector or damaged wiring
- PossibleBlown fuse on the circuit
- PossibleLow refrigerant charge preventing normal operation
- RareFailed control module driver
What you might notice
- Air conditioning cooling unevenly between front and rear
- Rear climate zone not cooling
- Air conditioning performance poor
- Check engine light on
- No effect on how the car drives
What to check, in order
- Disconnect the valve and check whether the low reading persists at the harness.
- Check whether one zone works and another does not. That pattern points at the distribution valve rather than at the system as a whole.
- Check the fuse for the circuit.
- Inspect the connector and wiring at the valve.
- Measure the solenoid winding resistance against specification.
- Have the refrigerant charge checked - a low charge produces poor cooling that looks like a distribution fault.
