Q: Throttle Position Sensor

asked by on September 29, 2016

Engine light on and was advised of code P0121 - Throttle position sensor malfunction. Just wondering if there is a part that is specific to my car and where I could purchase the part?

My car has 137000 miles.
My car has an automatic transmission.

The throttle position sensor is a very common part on most cars, however it is specific to your vehicle’s engine application. This is something that ca be purchased at most local auto parts stores (i.e. Autozone, Oreily’s, etc.) relatively inexpensively.
