Do you only need to change your knock sensor if you get an ecu code for it or can you check it with a voltmeter and see if it is going bad. My car is a 97 se with 95,000 miles. Just wondering because my car is running normal, but i could always use a little more power.

 

check the resistance with an ohm meter

 

how many ohms should it read 555? What if it is lower is it still ok or not?

 

one of this forums moderators said 500,00.
