Question Asked: Check engine light on despite new EGR value pressure sensor
January 24, 2009, 03:42 PM
The check engine light came on in my 94 Ford Escort after having transmission work done. The trouble codes are 335,326 and 172, and supposedly relate to the DPFE sensor. I installed a new sensor, but the light is still on. Does the computer reset right away, or is there something else wrong?
