Check engine light code P0120?

[cblankin]

My check engine light keeps comming on and going off. I retrieved the codes and it shows it to be a P0120 TPS/Throttle pedal position sensor "A" circuit malfunction. Has anyone had this code and what was the problem. I don't want to buy a Throttle position sensor just to find out that was not the problem. Advance Auto Parts wants $80.00. Has anybody purchased one from the Toyota dealer. I would appreciate any ideas or suggestions. Thank you very much. I have a 1999 Tacoma 4X4 Reg Cab 2.7 3RZFE 62,000 miles 5 speed manual transmission. Other than the check engine light being ON (sometimes) the truck runs great.

first check the connector remove and check if it has corrosion and needs cleaning or has moisture in it, sometimes just removing and replacing is enough to clean the pins.

I disconnected and reconnected the connector several times and the check engine light has remained OFF for several miles. I will drive it tomorrow and hopefully if will remain OFF.

So far the check engine light has remained OFF. The sugestion to disconnect and reconnect the Throttle positon sensor connector several times was an excellent idea. Thanks again
