P2A32AFCM Power Relay Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Gas installations that carry a separate control unit for the gas side, the AFCM, may feed that unit through a relay whose coil is switched by a driver stage. P2A32 means this coil circuit shows no current path: the driver output sees an open line, a missing plug or a burnt coil. Ford's 2003 bi-fuel CNG pickups show how such a module manages relays itself; it energises the ALT fuel relay feeding the tank and rail solenoids. No manufacturer publishes P2A32 itself, so the logic is inferred from the engine-module counterpart P0685: on Saab's 2010 V6, GM Europe compares commanded and actual driver state and reports a mismatch lasting 4 s, or 30 s in total. If the relay never pulls in, the gas side stays dead and a bi-fuel vehicle keeps running on petrol.
- What you may notice
- Check engine light, depending on calibration
- Gas mode cannot be selected, vehicle stays on petrol
- Dedicated gas engine: no start
- Likely causes
- LikelyBroken control wire or unplugged relay socket
- PossibleRelay coil burnt out
- RareBlown fuse in the coil feed of the relay
- RareOutput driver in the controlling module faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
