P045C: Understanding The Evaporative Emission System Pressure Sensor ‘b’ Circuit Low
The P045C 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.
The P045C code indicates that there is a low voltage or insufficient signal in the ‘B’ control circuit of the EGR system.
This can lead to improper functioning of the EGR valve and may result in decreased engine performance or increased emissions.
It is important to address this issue promptly to ensure the proper operation of the EGR system.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P045C could 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 diagnose the problem, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded pins on the connectors.
