P2CFE: A/C Clutch Control Circuit High

The A/C compressor clutch control circuit reports a control circuit high condition. Clutch engagement cannot be commanded reliably.

Low severity. Can I keep driving?Yes, you can keep driving. The air conditioning may not work.

Symptoms

Check engine or transmission warning light on
Harsh, delayed, or missing shifts
Possible limp mode (locked in one gear)
Slipping or shuddering during gear changes

Most likely causes

Control wire shorted to B+
Open clutch coil
Connector pins corroded - high contact resistance

What to check, in order

Start with the simplest. You can tick off each step.

Check the sensor pressure in live data
Check the sensor's ground and make sure the signal wire is not receiving voltage from another circuit.
Check the relay and connector
Have the refrigerant charge and any leaks checked at a repair shop authorized to handle refrigerant

Good to know

Repair difficulty: medium

What each character of P2CFE means

P: Powertrain: engine and transmission
2: Generic code: same on every make
C: Subsystem depends on the code range
FE: Specific fault in that system
