The automobile fault code P046D 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.

P046D: Fuel Level Sensor Circuit High Input – Understanding The Issue
The P046D fault code refers to a problem with the Exhaust Gas Recirculation (EGR) system’s sensor ‘A’ circuit. This code indicates an intermittent or erratic issue with the sensor.
The EGR system is responsible for recirculating exhaust gas back into the engine to reduce emissions. It consists of components such as the EGR valve, EGR solenoid, and EGR vacuum modulator. In newer vehicles, a step motor controls the flow rate of EGR from the exhaust manifold.
This motor operates based on signals from the Engine Control Module (ECM). The ECM controls the EGR solenoid, which in turn regulates the opening and closing of the EGR valve.
When the P046D code is triggered, it means that there is a problem with the sensor ‘A’ circuit of the EGR system. This could be due to intermittent or erratic readings from the sensor, indicating a potential issue with the EGR system’s functionality. It is important to have this code diagnosed and repaired to ensure proper engine performance and emissions control.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P046D 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, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, be sure to look out for broken, bent, pushed out, or corroded connector pins.
