Throwing a code

Alright guys need a point in the right direction. Been having issues with my 97 psd, thought it was a fuel issue but finally got around to pulling codes, only code it had is p0221. Sometimes at a stop CEL will come on and I push on the pedal and nothing. Usually after a few seconds it goes off and I go on my merry way. And also when driving down the roads so,etimes it seems to kind of "surge" like I am mashing on the accelerator intermittently. Hasn't been a big problem to me, I just don't want to end up stranded on the side of the road. Thanks guys

Travis

There are a couple of electrical items associated with the "throttle-by-wire" on these trucks. One is the Throttle Position Sensor (TPS) which is the 3-wire sensor on the pedal assembly. The other is the Idle Validation Switch (IVS) which is the 2-wire item on the pedal assembly. The IVS should be "open" when the pedal is in the idle position and close just off idle. The TPS should have a smooth transition (resistance change) with pedal movement. If you check them, I would do it with them disconnected (especially if you like to use a powered test light or something). Normally the TPS and IVS are replaced by replacing the entire pedal assembly, but there is a replacement TPS available that some have used with varying success. There are some posts somewhere on where to find an IVS, but I would have to search for it. One thing you can try is to get some electrical contact spray cleaner and spray the IVS and TPS while they are disconnected to see if that helps. Cheers!

Thanks Patrick, that's what I was afraid of, having to replace the whole assembly, but it's probably gonna be the best fix for it. Will try contact cleaner. These truck sure are money pits! But I'll take it over a car payment any day lol
