P2C55Cylinder 2 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
P2C55 reports that injector B of cylinder 2 needs the maximum offset the engine control allows: even with the longest permitted extension of its pulse it underdelivers. Volvo lists it in Technical Journal 36016 for 2022 model-year cars with engine variants L1 and 06. Version 4.0 of August 2021 still asked for model-specific special software, version 5.0 from September replaced that with a regular software release available from week 37 of 2021, again followed by an adaptation reset in VIDA. Cars treated before week 34 that showed the codes again had to be updated once more. Outside Volvo, a varnished or partly blocked injector, a high-resistance connector or, where the learn uses exhaust oxygen, a leak at the intake runner of cylinder 2 can drive the value up.
