CEL P0236 knock sensor performance
 

Hello Volvo fans,

I have a 1995 850 GLT sedan with 133,445 miles that runs great but has logged a trouble code P0236.
Is this a common failure. Any recommended tests to verify a knock sensor failure? Engine does not exhibit detonation on acceleration.
Resetting the code keeps the CEL light off for about 5-10 minutes of driving then sets the same code.
Any ideas and thoughts are appreciated.:D:confused:
