P2322Ignition Coil H Primary Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2322 is the counterpart to P2321: the coil H control line, cylinder 8 on most V8 layouts, reads as if it were tied to voltage. GM monitors it the same way on the 2019 LT5 and L84 engines, as a Type B code, flagged once 50 of 63 samples fail. Ford names P2322 in two special service messages from 2024: SSM 52455 for 6.8 and 7.3-litre petrol trucks (Super Duty, F-53/F-59, E-Series, F-650/750) and SSM 52342 for the Bronco. Both say the PCM may file the code under the wrong cylinder and will cut fuel to the cylinder it blames; a power balance test shows the cylinder that genuinely drops out. Ford's OBD summaries add that fuel to the affected cylinder stays off for 30 s and is cut again as soon as the fault reappears. GM PIP5147 also covers P2322 on 2014 trucks.
