P2006 Powertrain The intake swirl or runner flaps stay shut when the ECU wants them open, choking airflow… Moderate P200A Powertrain The ECU switched the intake runner flaps but the system didn't respond the way it should. Low P2015 Powertrain The sensor on the intake manifold flaps reports a position that doesn't match what the ECU… Low P204F Powertrain The DEF/SCR system isn't cutting NOx the way it should; ignored, it leads to a severe speed… Moderate P207F Powertrain The ECM thinks the DEF in the tank is too weak or contaminated, often right after a refill. Moderate P2096 Powertrain The sensor behind the catalytic converter keeps reporting lean, and the ECU has run out of room… Low P2097 Powertrain The sensor behind the converter keeps seeing rich exhaust, and the ECU can't lean the mixture… Low P20E8 Powertrain The DEF pump can't build or hold enough pressure; suspect a leak, frozen line, clogged filter… Moderate P20EE Powertrain The SCR catalyst isn't removing enough NOx; DEF quality, dosing, a NOx sensor or the catalyst… Moderate P219A Powertrain One cylinder on bank 1 runs clearly richer or leaner than the others, even if the average looks… Moderate P219B Powertrain One cylinder on bank 2 runs off the mixture of the other cylinders on that side of the engine. Moderate P2227 Powertrain The baro sensor's reading doesn't agree with the other pressure sensors or with what the engine… Low P2228 Powertrain The baro sensor signal is below its valid range, as if the car were far higher than any road… Moderate P2237 Powertrain The wire that carries the pump current of the upstream wideband (air-fuel) sensor is open. Low P2238 Powertrain The pump-current wire of the upstream air-fuel sensor is being pulled low, usually by a short… Low P2243 Powertrain The ECM lost the reference-cell signal of the upstream wideband sensor, as if the wire were… Low P2270 Powertrain The oxygen sensor after the catalytic converter won't show rich, even when the PCM deliberately… Low P2271 Powertrain The sensor after the converter stays rich even while coasting with the fuel cut off, when it… Low P2279 Powertrain Air is getting into the engine after the mass airflow sensor, so the computer isn't measuring… Low P2293 Powertrain The second fuel pressure control stage can't hold its target; on VW/Audi 2.0T often… Moderate P229F Powertrain The NOx sensor after the SCR catalyst is sending believable-looking but wrong or sluggish… Moderate P2400 Powertrain The engine computer can't drive the EVAP leak detection pump – usually a broken wire, bad plug… Low P2401 Powertrain The leak detection pump's control wire reads too low – most often a wire rubbing through… Low P2402 Powertrain The leak pump's control line reads too high – usually a short to a 12-volt wire… Low
