code 21

[vince1969]

code 21 comes up aswellas others such as 71 73 & 91 can ne 1 know how i can solve these?

[Blossey]

Code 21 - Throttle position sensor - voltage high
Code 71 - Intake air temperature - voltage high
Code 73 - Air flow sensor - voltage low
Code 91 - ????

Try doing a search on the forums for these codes to see if suggestions have been made already for them. You should find a few helpful ideas from there.

Other required information is what car do you have, what year, what problems are you experiencing?

More info needed.

21 N 71 are fairly close to eachother (sensor wise), check for broken earth straps onto the fuel rail, check sensors havnt been unplugged or wires mangled by work in that area.

73, sounds like it might be dead, tbh i don't think much can go wrong other than burning out and needing replacing. unless you have an 8v in which case agian its near the first two, and also less prone to failure.

Dunno what 91 is because i dont have my list here and Blossey hasn't defined it, i presume its therefore different for each model or not a valid code or something [img]/smile.gif[/img]
