Problem Description and Possible Solution
The Check Engine Light may come on with no driving issues noticed. If P0401, P0402, P1400 and / or P1401 are in memory, the Delta Pressure Feedback Exhaust Gas Recirculation (DPFE) sensor is at fault. The DPFE sensor should be replaced.

The check engine light comes on. I have replaced the fuel pump, sparkplug wires and plugs. The only work that was not done by me, I had a alarm put in. I bought a scanner and hook it up to the port. It did not work. I put on my other car and it worked. Any help is welcome.
