The automobile fault code P046C indicates a problem with the EGR (Exhaust Gas Recirculation) system. The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.
The code can be triggered by various issues, such as a faulty EGR volume control solenoid valve, carbon buildup on the EGR valve, open or shorted harness, poor electrical connection, or a faulty EGR temperature sensor and circuit. To fix the issue, it is recommended to visually inspect the wiring harness and connectors for any damage, and check for broken, bent, pushed out, or corroded pins on the connectors. The repair time for this issue is estimated to be around 1.0 hour.

P046C: Fuel Level Sensor Circuit Range/Performance – Understanding The Issue
The P046C fault code refers to the Exhaust Gas Recirculation (EGR) Sensor ‘A’ Circuit RangePerformance. This code is related to the EGR system in the vehicle. The EGR system includes components such as the EGR Valve, Engine Control Module (ECM) Controlled Vacuum Switch Valve or EGR Solenoid, and EGR Vacuum Modulator.
These components work together to regulate the opening and closing of the EGR Valve, which controls the flow rate of EGR from the exhaust manifold. In newer vehicles, a step motor is used to control the flow rate of EGR. This motor has four winding phases and operates based on the pulse signal from the ECM.
The valve opens or closes, changing the flow rate, when the ECM issues an ON pulse. 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 P046C fault code indicates that there is an issue with the EGR Sensor ‘A’ Circuit RangePerformance.
This could mean that the sensor is not functioning properly or that there is a problem with the circuit that connects the sensor to the ECM. It is important to diagnose and fix this issue to ensure the proper functioning of the EGR system and to prevent any potential performance or emissions problems.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P046C could be the culprit. This code is often caused by a faulty EGR volume control solenoid valve, carbon buildup on the EGR valve, an open or shorted EGR volume control solenoid valve harness, a poor electrical connection in the EGR volume control solenoid valve circuit, or a faulty EGR temperature sensor and circuit. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
If you’re dealing with the fault code p046c and your engine light is on, there are a few things you can do to fix it. Start by visually inspecting the wiring harness and connectors.
