Bank 2 secondary air pump runs continuously. Either a stuck-on relay or a shorted control output keeps the pum…
The secondary air injection system on bank 1 delivers more flow than calibrated when the pump is commanded on …
The secondary air injection system on bank 2 delivers more flow than calibrated when the pump is commanded on …
The differential pressure across the DPF is below the calibrated minimum even at higher loads. Often a sign of…
At engine off, the DPF differential pressure sensor does not return to zero within the allowed offset window. …
During an attempted regeneration of the bank 1 DPF the EGT did not reach the temperature window needed for soo…
Same as P244C with the EGT too high - regeneration paused to protect filter substrate from melt damage.…
During an attempted regeneration of the bank 2 DPF the EGT did not reach the temperature window needed for soo…
Same as P244D on bank 2.…
The EVAP switching valve does not respond to commands as expected. The valve is mechanically stuck or unable t…
The EVAP switching valve - which directs vapor flow between purge and leak-detection paths - is stuck in the c…
A general electrical fault on the DPF differential-pressure sensor circuit. Without a valid pressure reading t…
The DPF differential-pressure sensor produces a value that is electrically valid but does not match expectatio…
Voltage on the DPF differential-pressure sensor signal line is below the lower threshold. Typically a short to…
Voltage on the DPF pressure sensor line exceeds the upper threshold. Usually a short to supply or an open grou…
The DPF differential-pressure sensor delivers an intermittent signal — usually a marginal connector or a chafe…
The EGR cooler does not lower exhaust gas temperature as expected — typically internal coolant fouling, a part…
The DPF regeneration cycle takes longer than the calibrated maximum. The ECU sets this code when the soot load…
Active DPF regenerations are being requested more often than the calibration window allows. Indicates that soo…
The EGR cooler bypass valve on bank 1 - routes EGR around the cooler during cold-start to keep cabin and engin…
Same as P245A with the actuator electrically intact yet not delivering the commanded position. EGR mixes inert…
Same as P245A with the control line shorted to ground. EGR mixes inert exhaust into intake to lower combustion…
Same as P245A with the control line shorted to supply. EGR mixes inert exhaust into intake to lower combustion…
A general circuit fault on the secondary differential pressure sensor B across the DPF - measures backpressure…
