Angry check engine light

My 87 non turbo has had the check engine light on for about 2 years and i am really starting to get tired of the little yellow light that comes on EVERY DAY. i have got the code and it is number 53 which sayes that their is a short or open in the knock sensor circuit. i have replaced the sensor and that didn't do anything. just want to see if maybe someone had some ideas on how to make the light go away without removing the bulb.

thanks

Search this forum (and/or SM) for the knock sensor wiring repair. It seems that the wiring is an issue with these cars.

From my experience with OBDII cars (I know that the 87 doesn't have OBDII, but read on) when the troublecode indicator reads 'circuit', you have to consider three things -

A) The sensor itself.

B) The circuit, running from the sensor to the computer that interprets the information.

C) The computer that reads the information.


Along these three points, there can be failure, and any of them will cause the light to go on.
