I recently bought an '04 Tahoe. I've done alot of preventative maintenance stuff, since I don't know the history. Fuel pump/ sender assembly, oil pump and o-ring, timing chain and gears, rebuilt top end of the motor, and some other little things.
Currently, I have no passing gear when the pedal is floored. The scanner shows that the computer reads the throttle input up to 57%, but nothing more. I assume that there's no passing gear because the computer has no idea that the pedal is past 57%. Is this a throttle position sensor (under the hood) problem or an accelerator pedal position sensor (on the gas pedal) problem? Is it simply a replacement of the problem sensor or is there some sort of calibration involved?
I have an issue with the gas gauge reading backwards (full tank=needle on EMPTY and low fuel warning, needle travels toward FULL as the gas is used up), I haven't figured this one out yet, but I don't think it would have any relation to the lack of a passing gear.
Thoughts?
