I'm looking to help to correct my Check Engine Light.

I can't seen to find the problem which is causing my Check Engine light to come on in 1992 Crown Victoria. I pulled a 326 error code, Low volts to the DPFE sensor, with a Snap-On Scanner. I changed the EGR valve, cleaned the passages under the Throttle Plate elbow and installed a new DPFE sensor, but the same code keeps coming back.

Any suggestions?

The engine pings when the Check Engine light is on so I'm not sure if the pinging is from the EGFR system or bad O2 sensors? No error codes for bad O2 sensors?

Any help would be appreciated!

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.
