P0402
I've gotten a P0402 EGR "A" Flow Excessive code on my 95 2.3l. Most things I find online say to replace the DPFE sensor, but I don't want to throw parts at the truck. I'm up at college right now, and I didn't think to grab my Hanes manual or my factory service manual when I went home this past weekend.
What troubleshooting procedure do I take to diagnose the problem?

Problem has been solved. I had an open circuit in a DPFE sensor wire. This was completely my fault. About 8 months ago I unplugged the DPFE connector while working on the truck and the connector broke. I used a zip tie to hold the connector in place. Completely forgot about it, and the zip tie eventually forced one wire to internally break. Got a connector and bit of wire from pull a part and soldered it in. Now everything is perfect.
