knock sensor location
 
Hi... have a '91' 300e with 119,500 miles. I'm getting a code 25 knock sensor problem. Where is the knock sensor located?

thanks

Brian

I didn't think the 300E had a knock sensor ??? I know when it's close to 100 degrees outside, if I run 87 octane in my 91 300E I will hear pinging. I have to use 89 or 93 (premium).

California car that has the x11/4 diagnostic connector, count the number of LED flashes, gave 25 blinks.

Brian
but where did you read 25 is for knock sensor?

My mistake, looked at wrong codes. According to the proper code listing, the error is '25 Short to positive in start valve circuit'. What does that mean?
