Q: My car is in limp mode.

asked by on

Put a new throttle body on and the car is in limp mode.

My car has 65000 miles.
My car has an automatic transmission.

Hi there. Typically limp mode is triggered when there is a mechanical or electrical problem found in the transmission or drive train. The installation of a new throttle body may have triggered this alert if the battery cables were not removed (both positive and negative). It’s also possible that a sensor somewhere near the transmission may have triggered the error code upon starting the vehicle the first time. It’s best to have a professional mobile mechanic come to your location and complete a check engine light inspection, so they can trace any error codes stored in the ECU and determine why your car is in limp mode.
