Cel came on today got home did check and came up with code 22 and 41.iam not sure if i should just replace the sensors or what? Plus not real sure where they are located.by the way this is on a 91 4x4 pickup with 22re.any help whould be a blessing. Thanks.

 

well to start, your Throttle position sensor is located on the side of your throttle body. its has 2 screws in slotted holes holding it on. when i finished rebuilding mine I had 3 or 4 codes come on till i got it set right. http://www.4crawler.com/4x4/CheapTricks/TPS/index.shtml , this is a link a write up i used to set mine. it also has the test procedures for making sure it is functional. its a bit of a pain but when its set right it make a world of difference! test that first and hopefully it test out good then set it properly. after that recheck your ignition timing. that will take care of your code 41 and possibly your 22. all 4 of mine went when i set mine. good luck, let me know if that helped.

 

Come to find out the ect sensor had a broken wire.Thanks FRYsauce the link you sent me was helpful learned alot about tps that will be helpful in the future.
