What code is in the PCM? You need to have it scanned to see where to start

Ihave had the vehicle scanned a couple of times and it comes up code 121 which I was told was the tps sensor in which I just replaced.

At minimum you will need a meter to diagnose this or a scan tool. One of the threee wires is a 5 volt reference. One of theother wires should have around.5 volts at idle and it should increase to 5 volts at full throttle. If the minumum idle (idle screw) has been adjusted ori f it is having idling issues (IAC- Idle Air Control) it can also set a TPS code
