hi all i have a 2001 bonne se im getting dtc code p1404 egr closed position performance checked the egr valve out and the pintle moves freely by hand and the pipes were clear so i figured the motor that moves the pintle might have just went bad so i got a new egr valve and still the same light is there something else that could cause this thanks so much for you help
sorry took so long to get back i took the egr valve off and made sure the lines were clear and the pintle moved it did, so i put sealer and a gasket on to make sure it will not leak, then my buddy used his scanner to check out the computer and he can open and close the egr valve with it so im guessing that it has good power going to it.........i just want this light gone lol
Turn OFF the ignition.
Disconnect the EGR valve.
Turn ON the ignition, with the engine OFF.
Use a scan tool in order to observe the EGR position sensor parameter.
Does the scan tool indicate that the EGR Position Sensor is at the specified value? 0%
