P0363Misfire Detected - Fueling Disabled
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0363 is a reaction code: the engine module has detected misfire severe enough to damage the catalyst – through its crankshaft-based misfire monitor – and has therefore shut off injection to the affected cylinder or cylinders. CARB allows exactly this: a vehicle that cuts fuel immediately on catalyst-damaging misfire may turn the check engine light on steadily instead of flashing it, and may switch fuel back on to re-check at most every 30 s. The code names no cylinder; that comes from the accompanying P0301 ff. It is documented by code only at FCA: two reprogramming bulletins for the 2017–2018 Alfa Romeo Giulia 2.0 turbo list P0363 alongside misfire and mixture codes. Ford reacts in the same way without its own code, VW uses a manufacturer code (P130A) for the hidden cylinder, and GM does not list P0363.
- What you may notice
- Check engine light on steadily instead of flashing
- Clearly rough running, one cylinder without power
- Loss of power
- Jerking or stalling, especially when cold
- Likely causes
- LikelyIgnition coil or spark plug of the affected cylinder faulty
- PossibleInjector sticking or leaking, or fuel pressure too low
- PossibleEngine module software (misfire detection, cold-start mixture)
- RareMechanical cause: loss of compression, valve or carbon deposits, vacuum leak
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
