im not sure

well, my car threw a code today. performance is fine, the car hauls without stuttering. it threw a code 12, 22 and 54.
it shows that a code 22 is a tps, but a 54 can be many things. i think the book said something about a quad driver, so im thinking it may be the computer. how do i go about investigating this further, cause its been one heck of a month and this isnt helping at all.

Re: im not sure

Code 54 is for low fuel pump voltage. This is typically casued by the FP relay starting to go bad. At key-on, engine-off listen for the FP running for 2 seconds (key-off for 10 seconds before listening again). If no pump then check the relay.

The code 22 could be from the TPS going bad, or having it mis-adjusted. On the MAF ECMs the TPS adjustment is critical. There is a tech write up here on TGO for setting it. It may be in the 'minimum air setting' write up.
