I'm new on here,so here goes.I pulled codes on my 1993 Bonneville SE 3.8L.I got 2 codes #1 code 22 Thottle Position Sensor or circuit low (it has no power going to it).#2 code 56 my book doesn't list this code.Any help? Thanks in advance,Bert

Back to top. Help please

hey i have had some code problems myself and i am in the process of looking them up right now in alldata so if you can give me a bit more information maybe from the scan tool ill try and look them up for you

I ran a jumper wire in the ALDL from A terminal to B terminal it flashed code 22 & 56

Code 56 is basically a check code. Some will tell you it'* a known bug. Whatever, it'* nothing to consider. Aim straight at that TPS code by checking the connector and voltages etc.

Ok,Thanks for the help

Ok here is another stupid question.Where does the throttle position sensor get it power from?I have no power going to it.Does it get it from the brain box?
