What Does P2613 Mean?
The PCM detects voltage in the A/C refrigerant distribution valve control circuit that is higher than expected. This typically indicates an open circuit, short to power, or loss of ground in the control circuit.
Common Causes
35%
Open circuit in distribution valve ground or control wire
30%
Wiring shorted to voltage/power source
20%
Failed open A/C distribution valve solenoid
10%
Poor ground connection at valve or PCM
5%
PCM driver circuit failure
Diagnostic Steps
1
Step 1: Check for power at distribution valve control wire with key on, engine off (should be 0V until commanded)
2
Step 2: Verify ground circuit integrity at distribution valve with multimeter
3
Step 3: Measure resistance of distribution valve solenoid (should be within spec, not infinite)
4
Step 4: Check for voltage on control wire when valve is commanded off - should be near battery voltage
5
Step 5: Inspect wiring for chafing against voltage sources or damage near battery and alternator
Estimated Repair Cost
$100 - $600
Parts + labor, varies by vehicle and location
The PCM detects voltage in the A/C refrigerant distribution valve control circuit that is higher than expected. This typically indicates an open circuit, short to power, or loss of ground in the control circuit.
The most common cause of P2613 (A/C Refrigerant Distribution Valve Control Circuit High) is: Open circuit in distribution valve ground or control wire
Typical repair costs for P2613 range from $100 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive. A/C system may not function or may operate at reduced efficiency.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2613 to identify the root cause.
