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 the pulse signal from the Engine Control Module (ECM).
When the ECM detects a low voltage signal in the ‘B’ control circuit, it triggers the P045C fault code. This indicates that there is a malfunction in the EGR system, specifically in the control circuit responsible for regulating the flow rate of EGR.
If you encounter this fault code, it is important to have your vehicle inspected and repaired by a qualified mechanic. They will be able to diagnose the exact cause of the issue and perform the necessary repairs to ensure proper functioning of the EGR system.
