P2612
A/C Refrigerant Distribution Valve A Control Circuit Low
A/C & climate control
Generic OBD-II
Low
What it means
P2612 means the control module has seen low voltage in the control circuit for the A/C refrigerant distribution valve — typically a short to ground, an open, or a failed valve. It's a climate-control fault: the air-conditioning may cool poorly or unevenly, but the engine and drivetrain are unaffected and the car remains safe to drive.
Low
Can I keep driving? Safe to drive — this affects air-conditioning performance, not how the engine or car runs.

How to diagnose & fix
Work through it in order
- Confirm the fault with a scan tool and check for related HVAC codes.
- Inspect the distribution-valve connector and wiring for a short to ground or an open.
- Measure the valve's resistance against spec; replace it if out of range.
- Verify the control signal reaching the valve from the module.
- Repair the wiring or replace the valve as needed. Clear and re-test.
