P045D: Evaporative Emission System Pressure Sensor/Switch ‘a’ Circuit High
The P045D fault code refers to a problem with the Exhaust Gas Recirculation (EGR) system’s ‘B’ control circuit.
This circuit is responsible for regulating the opening and closing of the EGR valve. In newer vehicles, the EGR system uses a step motor with four winding phases to control the flow rate of EGR from the exhaust manifold. The motor operates based on pulse signals from the Engine Control Module (ECM).
When the ECM issues an ON pulse, the valve opens or closes, changing the flow rate. If no change in the flow rate is needed, the ECM issues a certain voltage signal to keep the valve at a specific opening.
When the P045D fault code is triggered, it means that there is a high voltage or excessive current in the EGR ‘B’ control circuit. This can indicate a problem with the EGR solenoid, vacuum modulator, or other components of the EGR system.
It is important to diagnose and fix this issue promptly to ensure proper functioning of the EGR system and reduce emissions.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P045D might be the culprit. This code is often caused by issues with the EGR volume control solenoid valve, such as an open or shorted harness, poor electrical connection, or problems with the EGR temperature sensor and circuit. To check for these potential causes, visually inspect the wiring harness and connectors, looking for any damage or corrosion. Additionally, check for any broken, bent, pushed out, or corroded pins in the connectors.
If you’re dealing with the fault code p045d and your engine light is on, it’s time to visually inspect the wiring harness and connectors related to the EGR volume control solenoid valve.
