Question

Engine running normally but auto zone tested because check engine light on. Code PO121 came up in test.

Is it safe to drive?

Answer 1

Hi there,

It is safe to drive but you may have some issues. The code is for the throttle position sensor, since it's part of the throttle body the car could go into fail safe mode on you. This would give you enough power to get it home but it won't have much more then that.
