I checked my TPS with a multimeter and it seems to be giving out bad voltage, when I increase the throttle it increases in some areas and decreases dramatically in some areas of the tps. Also the error code corresponds to the TPS sensor(41).

So now that I've established a bad tps, I went online to check for them and the model was nowhere to be found. Is it critical that I replace the current tps with the same model as before?
