P0405 and P1404 code what parts to fix

Question

Hi, i already change my egr valve, clear the code , but still have P0405 and P1404 code , sometime stall , what parts should i change , thanks Dom

Answer 1

P0405 EGR sensor circuit voltage out of range

P1404 EGR valve pintle stuck open

The EGR is stuck open , you have to remnove the EGR valve and check to see if there is any carbon that may have gotten stuck , this would cause the engine to stall when coming to a stop. You may have a faulty EGR , the EGR pintle being stuck open and having a P0405 where there is a problem with the sensor not seeing its voltage
