Hi, i'm new on this forum and my 99 Mirage 1.5 de coupe has a chronic p0120 trouble code
P0120 Throttle Position circuit.
I've already replaced the TPS sensor, and that didn't change a thing. The car hesitates when i touch the throttle and at low speeds the throttle cuts out intermittently. I've seen a lot similar problems... but not sure what to do to fix this. The spark plugs and air filter are new.
Thanks =)

 

i dont know mine does it, with no error code and no check engine light on.
when you find out what it is let me know :]]

mine does have 289,000 miles give or take a few hundred miles.
mine may just need a complete rebuild.

is yours a high mileage car??

 

are u sure its the code P0120?i look it up i couldn't find that code at all?

 

yeah, it's P120, has been since i've gotten the car

this is the OBD II codes list in the diy thread
P0120 Throttle Pedal Position Sensor/Switch A Circuit Malfunction

My car has 118K miles. The TPS was replaced at around 109K.

 

is it positioned correctly? i had the same problem, ended up having to bite the bullet and take it to a dealer to have them adjust it cuz i couldn't get it quite right. i'd also check your wires, cap & rotor just to be sure.

 

Thanks... I'll have to do that and let you know how it works........
