thank for our help
P0404 - Exhaust Gas Recirculation Circuit Range/Performan
The EGR (Exhaust Gas Recirculation) system's purpose is to redirect exhaust gas back into the cylinders.If the PCM determines that the valve should be operating, but the feedback circuit shows that the valve is not open,or in a wrong position, this code will show up. Most likely what's happened, is the EGR valve is all carboned up inside and is not functioning properly.It's staying open all the time. I would start with replacing the EGR valve. The EGR is located on the front of the front cylinder head, and has a tube that runs to the top of the plenum.
The other reasons for a P0404 according to the manual are
GOOD TRIP EQUAL TO ZERO
HIGH RESISTANCE IN 5 VOLT SUPPLY
EGR SOLENOID CONTROL CKT
EGR SENSOR SIGNAL CIRCUIT OPEN
EGR SENSOR SIGNAL CIRCUIT SHORTED TO GROUND
SENSOR GROUND CIRCUIT OPEN
EGR ASSEMBLY (GROUND)
Let me know what engine size and exactly what year you have and I will try to get the service manual posted for you. Good Luck
Okay here is the complete Service Manual for you. It does have your error code in there as well as all the steps to diagnose your error. Hope this will get you on the road again...;-)
