When I bought my 87 runner the guy told me the check engine light was on due to a bad knock sensor. I have no experince with a knock sensor was hoping you guys can tell me if it makes sense.
The light only comes on once the motor hits 2K rpm and then stays off until I shut the motor off. The motor is running fine and Im getting a little over 20 mpg.
Does this sound like its a knock sensor? And if so if I replace it should I notice a difference in how it runs, or my mpg?
Im just trying to decide if its worth replacing, the guy I bought it from said its a spendy part.
