2008 chrysler T/C egr valve problems
I replaced the egr valve and the map sensor, but I
still get codes P0405, P0406. It also has a lot of
roughness in the engine. What could be the cause
Does it run rough at idle and low RPMs or high RPMs? The EGR should be closed at low RPMs, but if there is something wrong with the circuit or sensor, it will be stuck open and cause an engine to run rough (exhaust gases burn slower and at lower temps).
Mostly rough during periods of deceleration or low RPM.
At lower idle it may be a sign the EGR valve it still open when it should be closed. Either a faulty EGR valve or sensor or circuit.
