Posted:11/29/2003 18:47 I looking for help to solve my Check Engine light problem. I pulled a 326 code, low volts to the DPFE sensor, with a scanner. I changed the EGR valve, cleaned all the EGR ports under the throttle plate elbow and installed a new DPFE sensor, but the same code keeps coming back. Any suggestion? The engine pings when the check engine light goes on so I'm not sure if the EGR problem is causing the problem or bad O2 sensors. I haven't pulled any codes for bad O2 sensors. Any help would be appreciated! KK

Posted:12/11/2003 16:07 Did you disconnect the battery when you replaced the sensor? I had the same problem. I had to replace the sendor due to voltage being too high. Had to replace the tube that runs from the EGR to the exhaust manifold because it was broke. This took care of my CEL. Try that if you haven't and let me know what happens.
