Same as P04C8 with intermittent or erratic signal - typically a connector or harness fault. Wiring faults of t…
The open-request switch is stuck in the active state - the ECU continuously reads a request to open the fuel f…
A general circuit fault is detected on the third EGR temperature sensor (C) - typically used on systems with m…
Same as P04CE with the signal in plausible range yet not matching the engine model - typically sensor drift or…
Same as P04CE with the signal voltage below the plausible range. EGR mixes inert exhaust into intake to lower …
Same as P04CE with the signal voltage above the plausible range. EGR mixes inert exhaust into intake to lower …
Same as P04CE with intermittent or erratic signal. EGR mixes inert exhaust into intake to lower combustion pea…
The exhaust brake activation input - typically from a stalk lever, brake pedal switch, or vehicle bus message …
Same as P04D3 with the signal in plausible range yet not matching expected behaviour - e.g. activation request…
Same as P04D3 with the signal voltage below the plausible range. The exhaust control valve modulates exhaust b…
Same as P04D3 with the signal voltage above the plausible range. The exhaust control valve modulates exhaust b…
Same as P04D3 with intermittent or erratic signal. The exhaust control valve modulates exhaust backpressure or…
After cold start the ECU operates EGR open-loop until preconditions (cooler temperature, sensor warm-up, engin…
With EGR running in closed loop the controller has driven the actuator to its maximum opening but cannot reach…
Same as P04D9 with the controller fully closing the actuator yet still measuring more EGR flow than required. …
A pressure or flow sensor in the crankcase ventilation (PCV) circuit reports atmospheric conditions where it s…
Same as P04B8 with the signal in plausible range yet not matching the actuator command - door reports closed w…
During the cold-start strategy the ECU briefly opens EGR A to slow combustion temperatures and reduce engine-o…
Same as P04DD with EGR flow above the cold-start target - typically valve sticking open during the cold phase …
The EVAP purge valve B is mechanically stuck open or its feedback indicates flow even when commanded closed - …
Same as P04AF on EVAP purge valve A. The evaporative system captures fuel vapor from the tank and purges it in…
A dedicated sensor monitors whether the PCV hose is fitted to its connector at the engine. The ECU detects a c…
