I got SEL on in my car and diagnosis say 2 codes P325 and P125. Tech. has told me replace Knock sensor but not sure if that will fix the problem. Any advise or help on how to address the problem.

Knock sensor is used by computer when it senses spark knock it can either retard the timing or advance it ....if the knoxk senssor is picking up other noise like engine noise replacemnet of sensor won`t do anything ...need to run diagnostic chart and go from there ......not a common problem ...
