    Question Service Emissions System

    I have a 96 Sedan Deville that has a Service Emmisions system coming across the DIC. When I put it on the scanner the only code coming up is P0325 which indicates KNOCK SENSOR circuit. I replaced the sensor and the emissions light is still on along with the service engine soon. Any one have any ideas of how to check what is wrong, without taking it to the dealer?

    Did you clear the code after fixing the problem...??? Disconnect the negative battery terminal to send the code to history status and see if the light goes out.
