P2C53Cylinder 1 Fuel Injector B Offset Learning At Max Limit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2C53 is the opposite end of the injector B offset learn on cylinder 1: the engine control has lengthened the command as far as it may, and the cylinder still gets less fuel than requested. Ford patents describe the offset as the time the pintle and the driver circuit need before fuel moves, so a sticky or varnished valve or a weak supply raises it. Volvo documents the code: Technical Journal 36016 (2021) lists P2C53 together with P2C55, P2C57 and P2C59 as permanent ECM faults on 2022 model-year cars of types 224 to 246 with engine variants L1 and 06, usually without any drivability complaint. The remedy was new engine software followed by a reset of the injector adaptations in VIDA with the engine running, strictly in that order.
