Q: Lightning bolt symbol

asked by on

Our engine light came on and it read that the cam shaft needed to be replaced we replaced it but came to find out our car has 2 of them well the lightening bolt symbol came on today is it related should I worry

My car has 168000 miles.
My car has an automatic transmission.

The red lightning bolt indicates that there is a problem wit the electronic throttle control unit. This may be for a specific reason or may be due to a slight glitch. Try resetting the throttle control unit by doing the following:

Insert ignition key and turn to "ON" position but do not start the engine Wait for all the warning lights to go out. The check engine light may remain on. Slowly depress the accelerator pedal all the way to the floor. Slowly release the accelerator pedal until it is all the way back up at the rest position. Turn the ignition key to "OFF" position. Start the engine and test the throttle by see if the engine will throttle up.

This is often a procedure that must be repeated in the event the battery is ever disconnected. You will also want to have the computer scanned to check for any fault codes that may have been logged as a result of the lightning bolt showing up in the dash. If this does not correct your problem, I would suggest having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
