hey guys im trying to find a new throttle body or the sensors that are mounted on it. im getting trouble codes p1221 and p1515. plus the reduced engine power light is on. its a 2002 3.8 v6. what are the sensors called. theres one on top with 2 screws and one on the side that is rivited on. where can i buy these sensors? i dont think i need to replace the whole throttle body just maybe 1 or both of the sensors. i just dont know where to buy them at. need help

 

The one on top is the maf sensor. The one on the left side is the throttle position sensor. Should also be held on with 2 screw. The one on the right is the electronic throttle control. Leave that one alone. That's why it's rivited on.

 

The code says its your TPMS sensor. Try zeroing it out. To do so unplug it, turn the key to on and count for 30 seconds. After 30 seconds turn the key off and plug it back in. Could be a bad TPMS sensor.

 

Have you cleaned your MAF wire with MAF cleaner? Try that first, and be certain not to touch the wire...

 

ok well the sensor on the left is riveted on and i cant find any place that sells it separately. and that is the tps right??? the one on top is the maf i know that. but i need to know if the one on the left is sold separately and where to buy it from. like i said i cant find it anywhere. so it seems like i have to buy the whole throttle body assembly to get the throttle position sensor.

 

let me know if im wrong about that guys.

 

Did you try re-zeroing the tpms like I suggested above? I looked up the code and someone said replacing the throttle body fixed the issue.

 

yes i did zero it out it worked and the reduced engine power lite went off and the car worked perfect for about 20 min and then the lite came back on and is still giving me problems. im gona try and find a used throttle body and see if that works. dont have time to work on it till next week but ill let u guys know. thanks

 

The only throttle body that well work are 99-02 Camaro 3.8 throttle bodies. Post some pics of your throttle body. Makes things a little easier
