Car has to be restarted to drive again. Can someone tell me what cause this? Is it a sensor and if so which one?

Hello,

There are several reasons for a vehicle to go to limp mode (low power mode). The limp mode gets triggered to protect engine or transmission components. Typically for some type of sensor or module.

Usually you will have the check engine light being illuminated when the car goes to limp mode.
Is your engine light on?
Retrieving the codes can help diagnose the reason why this is going into limp mode.

Please let me know.
Thank you.
