Motor (P)
Same as P049A but with measured flow above the required rate - typically EGR valve sticking open or position s…
The ECU continuously learns offsets for the EGR A actuator to compensate for soot buildup and ageing. The lear…
A general circuit fault is detected on the second exhaust pressure control valve (B) - used for example on dua…
Same as P049F with feedback in plausible range yet not matching the engine model - actuator slow, slipping or …
Same as P049F with the control line shorted to ground.…
Same as P049F with the control line shorted to supply.…
Same as P049F with intermittent or erratic feedback - typically a connector or harness fault.…
The exhaust pressure control valve B is mechanically stuck in the open position. The ECU commands closing for …
Same as P04A4 but the valve B is stuck closed - back-pressure stays high even when the engine should run with …
A circuit fault is detected on the position sensor of exhaust pressure control valve B. Without valid position…
Same as P04A6 with the signal in plausible range but not matching the actual valve angle.…
Same as P04A6 with the signal voltage below the plausible range. Wiring faults of this kind typically come fro…
Same as P04A6 with the signal voltage above the plausible range. Wiring faults of this kind typically come fro…
Same as P04A6 with intermittent or erratic feedback - typically a connector or harness fault. Wiring faults of…
The second EVAP purge control valve (B) - used on systems with a divided purge path or on twin-bank engines - …
Same as P04AB with the control line shorted to ground. The evaporative system captures fuel vapor from the tan…
Same as P04AB with the control line shorted to supply. The evaporative system captures fuel vapor from the tan…
The EVAP purge valve B is mechanically stuck open or its feedback indicates flow even when commanded closed - …
Same as P04AE but the valve B is stuck closed - no vapor purge possible through this stage, leading to elevate…
The refueling vapor control valve - typically part of the ORVR or capless fueling system - has an open control…
Same as P04B0 with the control line shorted to ground. Wiring faults of this kind typically come from chafing,…
Same as P04B0 with the control line shorted to supply. Wiring faults of this kind typically come from chafing,…
The refueling vapor control valve is stuck open. Vapor pathways meant to be closed except during refueling sta…
