P0CF6Control Pilot Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- A pilot level above the valid range usually means the line touches a supply voltage, or the measuring path in the module reads wrongly. GM evaluates it on the Chevrolet Volt (VICM/HPC2, 2012-2019) only while no cord is connected and the car is travelling at 8 km/h or faster, a moment when the pilot should be practically dead: a normalized pilot voltage (pilot voltage over battery voltage) above 0.55, or 0.58 in the 2012 table, in 30 of 50 samples at 100 ms sets the code. It is Type A, so the MIL comes on after one trip. The low-side counterpart is P0CF5, plausibility errors belong to P0CF4, an open line to P0CF3. With the pilot held high, the vehicle cannot pull the level down to request energy, and the station does not switch power on.
- What you may notice
- Malfunction indicator lamp on after a drive (GM Type A)
- Charging does not begin at the station
- Charging fault message in the cluster
- Likely causes
- LikelyPilot wire shorted to a 12 V feed in the harness or inlet
- PossiblePilot measuring circuit in the charging control module reading too high
- RareMoisture in a connector coupling a neighbouring voltage onto the pilot
