Hey guys i have a replaced the tps sensor with one from the wreckers and seem to not change anything. Could there be something else giving me this problem or have i probably wasted money on a dodgy tps.
TPS are very sensitive, if you look at it the wrong way you can %$#& it up! I wouldn't buy one from a wrecker for that reason, and a new one only costs $50-$80 depending on where you get it. Seen them on ebay pretty cheap, should be OK if Genuine.
Are you sure you reinstalled it correctly? Using a volt metre, check the reference voltage from the PCM. Connect the positive probe (+) onto the reference wire (Grey) and the negative probe (-) onto the earth wire (Black/Yellow). The voltage should read approximately 5.0 Volts. Next, check the TPS signal voltage. With the throttle fully closed, connect the positive probe (+) of the volt meter onto the signal wire (C Terminal on the TPS) and the negative probe (-) onto the earth wire (B Terminal on the TPS) Gradually open the throttle and observe the TPS sensor voltage. There should be a smooth change in the voltage values as the sensor travels from idle to full throttle. The voltage should increase to approximately 4.5 to 5.0 volts.
Thanks guys for all the help. All the voltage seemed to check out so i went out for another TPS. Got one for 35 and seems to be running sweet now
