P0ECE A/C Refrigerant Distribution Valve A Control Circuit Low
The A/C refrigerant distribution valve A reports a control circuit low condition. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Is it safe to drive with P0ECE?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
