The secondary fuel system B on bank 2 (e.g. port-injection rail in a dual-injection engine, or LPG/CNG rail in…
The control circuit to the EVAP leak-detection pump is open. Without that pump the ECU cannot pressurise the f…
Drive voltage on the leak-detection pump line is below the lower limit. Often a short to ground in the harness…
Drive voltage on the leak-detection pump line is above the upper limit. Usually a short to supply or open grou…
The leak detection pump (LDP) - which actively pressurises the EVAP system to find leaks - has an open sense c…
The sense (reed-switch or current-feedback) signal from the leak-detection pump is electrically valid but does…
Same as P2403 with the sense voltage below the plausible range. The evaporative system captures fuel vapor fro…
Same as P2403 with the sense voltage above the plausible range. The evaporative system captures fuel vapor fro…
The leak detection pump returns a sense signal that is electrically valid but does not match the expected resp…
On vehicles with a sensed fuel cap, the cap-status signal is electrically valid but does not change as expecte…
The sensor or switch that detects whether the fuel cap is properly closed reports a value within plausible ran…
The leak detection pump heater - keeps the pump diaphragm warm in cold weather - has an open control circuit.…
Same as P240A with the control line shorted to ground. The sensor heater warms the element to operating temper…

A leak detected in the low-pressure side of an alternative fuel system (LPG, CNG between regulator and rail, o…
The EGR system reacts to commanded changes more slowly than calibrated - typically a partly clogged EGR cooler…
The fuel cap status switch is stuck in one position — the ECU never sees the expected transition between open …
A general electrical fault on the fuel cap sensor/switch circuit — open or short.…
Same as P2409 with intermittent or erratic signal. Wiring faults of this kind typically come from chafing, wat…
The ECU monitors EGR flow indirectly through MAF, MAP or differential-pressure feedback and finds that actual …
Same as P237A but on the upstream sensor B1S1 (pre-catalyst). A drifted or sluggish lambda sensor lets the mix…
The ECU detects an open circuit on the EVAP switching valve drive line. The valve cannot be commanded between …
The EVAP switching valve responds electrically but does not produce the expected pressure change. Often a stuc…
