Q: Limp Mode

asked by on May 31, 2017

My car is in limp mode how much would it be to fix that problem? I won't go above 40 mph without hesitating.

My car has 141000 miles.
My car has an automatic transmission.

There are a number of things that may cause the vehicle to go into limp mode such as faulty transmission control components or various engine control components. Typically, when this happens the check engine light will come on triggering some fault code(s) that will indicate more specifically what may be causing this to happen. Generally, the check engine light comes on when something fairly serious is going on with the vehicle. This can happen for many different reasons such as a faulty mass air flow sensor, a faulty O2 sensor, a bad catalytic converter, bad spark plugs or spark plug wires and many other reasons. Due to the wide range of possibilities for the check engine light to come on, the best and most efficient way to narrow down the scope of what may be causing this is to have the vehicle hooked up to a scanning tool to download any potential fault codes that may have registered in the computer. This will allow a mechanic to determine more specifically what to look for in diagnosing your vehicle. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your check engine light to come on.
