Question

2002 Ford Focus 2.0L, will this make my transmission go in and out of gear? I got the code P0122 and P1120

Answer 1

HI there,

Both of these codes are for the throttle position sensor on the car. If the computer isn't getting the proper input from this sensor, it will make the cars shifting pattern all over the place. With this code normally you need to replace the TPS and once done, see if the shifting is no longer a problem
