What does exhaust gas recirculation control circuit range performance mean?

What does exhaust gas recirculation control circuit range performance mean?

It is a generic OBD trouble code that activates if the powertrain control module (PCM) detects erratic Exhaust Gas Recirculation (EGR) valve performance. It could mean that your EGR valve isn’t doing what it’s supposed to do in specified parameters such as being fully open when it should only be partially open.

What does P0405 code mean?

Diagnostic trouble code (DTC) P0405 stands for “Exhaust Gas Recirculation Sensor A Circuit Low.” It denotes that the readings coming from the EGR valve position sensor show lower voltage levels than normal. If the signal from the sensor appears strangely low, the PCM may set a P0405 code.

How do I fix code P0403?

What repairs can fix the P0403 code?
