What is the diagnostic code for exhaust gas recirculation?

Cost of diagnosing the P0403 code. P0403 is a diagnostic trouble code (DTC) for “Exhaust Gas Recirculation Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

How does an exhaust gas recirculation valve work?

There are different designs of EGR (Exhaust Gas Recirculation) systems, but they all operate in a similar way. The EGR valve is a PCM (Powertrain Control Module) controlled valve that allows measured amounts of exhaust gasses to pass back into the cylinders to be burned with the air/fuel mixture.

What does exhaust gas recirculation ” a ” circuit range?

Exhaust Gas Recirculation “A” Circuit Range/Performance What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.

Why is my p0404 exhaust gas recirculation not working?

The actual EGR position should be very close to the “desired” EGR position. If it is, then the problem is likely intermittent. It may have been a lodged piece of carbon that has since dislodged, or it could be a bad EGR valve winding that intermittently opens or shorts as the valve temperature changes.

When to replace the EGR valve connector p0405?

If, after jumpering the 5 volt reference circuit to the EGR signal circuit the scan tool EGR position reads 100 percent, then check for poor terminal tension at the EGR valve connector. If the wiring is okay, replace the EGR valve. Related EGR codes: P0400, P0401, P0402, P0403, P0404, P0406, P0407, P0408, P0409
