If your vehicle has stored a code P042E, it means that the powertrain control module (PCM) has detected a problem with the exhaust gas recirculation (EGR) valve control system. In the case of the P042E, the valve appears (to the PCM) to be stuck in the open position.

OBD-II Code P042E means the Exhaust Gas Recirculation 'A' Control is Stuck Open, which can result in decreased engine performance.2d2a

2024年9月5日 · This diagnostic guide will help you resolve the P042E code by ensuring that the EGR valve, wiring, and related components are functioning correctly, allowing the engine to maintain optimal emissions control and performance.

2021年12月25日 · The error codes I am getting is P042E and P042F which point to the EGR control valve being stuck open and closed. So my first instinct was to take the valve off, but there I already read that it's recommended to do this while the valve is energized, guessing it has to do with the fact that it keeps the valve in the retracted position, so that ...

The fault code P042E can be caused by a faulty Exhaust Gas Recirculation (EGR) Valve, an open or shorted harness for the EGR Valve, a poor electrical connection in the EGR Valve circuit, or a faulty Engine Control Module (ECM).

This DTC sets when the EGR setpoint is less than a specified threshold, the actual EGR position is greater than a specified threshold, and the EGR control limit is less than a specified limit. The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power.

2024年3月24日 · Code P042E Description. The Engine Control Module (ECM) uses the Exhaust Gas Recirculation (EGR) position sensor to determine the position of the EGR valve. The ECM sends a reference voltage through the 5 V reference circuit to the EGR position sensor. The ECM provides a voltage return path for the sensor through the low reference circuit.
