P02xx codes: injectors, fuel pumps, turbocharger boost and over-temperature
125 codes in this range, all generic — the same meaning on every make. The sensors the engine computer meters fuel from — mass air flow, manifold pressure, intake air and coolant temperature, throttle position, oxygen sensors and fuel pressure — the fuel trims it learns from them, and the injector, fuel-pump and turbocharger circuits.
What usually causes codes in this area
- Dirty or failed sensors — the mass air flow and oxygen sensors most often
- Vacuum and intake leaks
- Fuel delivery: pump, filter, pressure regulator
- Wiring and connectors
- Injector faults
Can you keep driving?
Usually drivable in the short term, with rougher running and worse fuel economy. Don’t leave mixture codes for weeks — a lean or rich engine damages the catalytic converter over time — and treat an injector code that comes with a misfire as urgent.
