How To Fix P0304 Engine Code In 5 Easy Steps Automotiveglory The p0406 fault code indicates a problem with the egr system, specifically the egr position sensor. while this problem may seem tricky, most repairs, such as cleaning the egr passages or replacing the sensor, can be completed with just a few basic tools and patience. If this sensor detects that the valve is not opening and closing properly, it will send the p0406 error code. essentially, this means that the exhaust gas recirculation system is not functioning correctly, which may cause several symptoms that impair your ability to operate your vehicle. Diagnosing this error involves checking various components of the egr system and its wiring connections. once identified, fixing it may require replacing the egr sensor itself or addressing wiring issues. knowing these key points will empower you in dealing with this automotive challenge effectively. The p0406 code means that the engine control module (ecm) has received a signal from the egr position sensor that is higher than the acceptable values. this could indicate a faulty sensor, its wiring, or a fault within the control module.
