Error Code 335 - Check Engine Light on.

[Brett]

1994 Explorer Sport 4.0L 5spd.

Has anyone had experience with a 335 Error Code. The manuals say EGR voltage higher or lower than expected. Now, before I start throwing money into this problem, I was wondering if anyone has had a similar problem.

Thanks for the help. I'll keep this updated.

For what it's worth....If you aren't getting any other symptoms except for the check engine light I have a minor test. I have a Ford Crown Vic that kept having check enging light problems...after several trips to the mechanic we (he) finally decided that it might be an old error code stuck in memory. The mechanic tried removing the negative battery cable for about 5 minutes and re-attaching it so the computer would reset. This costs no money and could solve your problem if it's very minor. If there is something more, the check engine light will come back on and you will have to investigate (or pay) further.

The "codereader" manual should tell you how to clear the code..Is the performance affected at all?

I have cleared the memory codes, however, they do return. The manuals refer to an EGR sensor, however, there are several sensor's that are part of this system. I just want to pinpoint the sensor before I pour a bunch of money into swapping parts. The performance has not been affected. I also get a 326 error code while the engine is running.
