I ran a diagnosis on my vehicle and it gave this codes P0122 (throttle positioning sensor low circuit), P0113 (intake air temperature sensor circuit high voltage), P0141. Pls can anyone give me a proper solution to dis problems as I've spent so much money in trying 2 fix it wit the mechanic butstill no result, I just changed d throttle positioning sensor with a used one (with the throttle body), dis is the 3rd one now, before that I bought a brand new 1 but still no result and dis same codes keep coming up. Pls pls pls a gud reply will be really appreciated. Thank u

The code only indicates a problem with the circuit, not necessarily the sensor itself. It could be a wiring problem or even a bad computer but the circuit needs to be troubleshooted and diagnosed properly.

It means test that all the correct signals are in the correct places, not really something for a novice.

Ok, so I did as u told me and saw d harness to d intake air temperature sensor is broken and d wires seem to be touching each other, I really don't knw how dat happened, so I changed d harness and d codes are gone but I've another code on now and it is d only code, it is p1157, I'm having a feeling dat d previous problem has probably triggered or damaged d sensor or wat do u feel and how can I get rid of dis also, should I just go ahead and change d sensor or check d wires as u instructed?

If the wiring looks OK, it's probably ab bad 0/2 sensor.
