EEC code for Throttle Position Sensor
hey, I just had my codes pulled at autozone and he said that it pulled two codes, the pass code and code 122 which was throttle position sensor low voltage.
anyone have any experience with this code? any ideas?
thanks!

All kinds of posts on this board on TPS. Your idle messed up? may be time to change it. Not sure what pass code is. If you need a guide on replacing the TPS let me know I will post what I have from one of two serivce programs I have on imageshack.

ok, will check some more on the site, but it idles just fine. He said that it could cause the truck to run rich, but it seems to run fine right now
we looked them up in a haynes manual right in the store, the pass code simply tells you that the testing procedure is working properly from what we read.

To late to edit, so sorry about double posting.
All i found when doing my searches was people that were having bad problems with the engine idling and running poorly, but my truck runs fine. Could it just possibly be in the very early stages of going bad? just low enough to send the code, but not to affect the engine yet? just an idea, but I dont know.

autozone will do it for free, I didnt even go to one that had a shop, just a parts store and the attendant came out to the parking lot and pulled the codes and then looked them up in a haynes manual for me, pretty good service if you ask me, since it was about 5 above and wind blowing like 20 mph - makes for a chilly day

You have three tests available, the first one is the basic "key on engine off"
The computer does a quickie test of your relays, sensors, and switches. If any electronics are failing you would get a code..but you passed that test.
The second set of codes (or second test) is the continous memory code, these are all of the stored codes during the last 80 times you drove tha truck, or, all stored codes back to the last time the battery was disabled, or the codes were manually reset. Your TPS code may have been stored 2 months ago, after one intermittant failure of the TPS. There is no way to tell how many times the TPS failed, but you do know it failed at least once.
The third test, which you didn't mention, is the dynamic test with the engine running.
Personally I would ignore the TPS code..If it were me I would rest the computer ..see fordfuelinjection.com and/or the Haynes both have the procedure. Then if the code 122 returns in a day or two after doing a second test, your TPS may have a reproducible error.

PS PS PS ...Everyone on this site better learn how to pull your own codes!
It is the best way to keep up on what is happeneing to your truck. I can pull the codes on my truck in 2 minutes. Once you learn the procedure and practice it..you will do it often, i.e. at every oil change, etc.
For earlier trucks, up to 1995 or so, the computer codes can be pulled by using a paper clip, pencil, and you need to observe the check engine light.
Please research pulling the codes, there are two connectors on the drivers side inside fender that need to be temporarily shorted..that is all.
Find the procedure (it should be on this website a 100 times) or look into buying a Haynes/chilton/Ford Manual, Or Go to Fordfuelinjection.com

yeah, i have heard about the paper clip solution, but I have an autozone a couple blocks away, and i knew they had a haynes manual there, so i figured, have them pull it then I can look it up right there

dont take this like I am a thread **** and I am mad for hijacking a post (i am not) but you would probably get a better response if you started your own thread, it would probably get noticed a lot easier that way.
Sorry, I dont know how to help you, but good luck!

Also, I haven't seen one for a while, but Wal-Mart used to stock a small OBD-I (primarily for pre-'96 Fords) code reader for $25 that is about the size of a pack of cigarettes. I purchased one at Wal-Mart 2 years ago & keep it in the glove box. I pull codes while waiting for my wife to finish at the grocery store. It came with a very detailed booklet describing the 3 procedures (KOEO, etc) & codes (in 4 languages no less, Si). It doesn't do anything useful you couldn't do by the paperclip process (except store pulled codes in the code reader for future reference - why, I don't know), but it is right handy & not much more expensive than a new Haynes manual alone.

You can go to AutoZone to have them pull your codes, but good luck. They can only test OBDII vehicles (1996 and newer.) You have an OBDI system. Do it yourself, you'll learn something. You'll be much better off in life if you can do things yourself, rather than relying on a high school drop out to try to find the diagnostic plug thats not in your cab because you don't have an OBDII vehicle.
