Here is a thread on 51; http://www.supramania.com/forums/showthread.php?46793-Code-51 . Be sure the your tps is calibrated properly (http://www.mkiiisupra.net/joomla/index.php?option=com_content&task=view&id=38&Itemid=29).

Finally if you replaced the knock sensor and you are still getting 52 (the code will make your car run like crap), that is usually an indication that the wiring is bad and need to be redone. There is a nice write-up on here as to how to accomplish that.

Thanks how many knock sensor does 7 mge have? And which color of wire should I hook it up on ecu to positive knock sensor single wire? T.y.

GW has 1 knock sensor. Check TSRM for wire colors.

Do the coax wire mod while your at it...

You will also need to make sure that you have a good ground when you are rewiring the k.s. Do you have a good test light and multimeter?

 

[ashiharausa]

I will borrow a volt meter so if a ground which is negative black from the ecu goes to the body of the knock sensor?

 

[T3rril79]

I'm not following your question.

 

[ashiharausa]

Where do I place the coax Negative wire one in the chasis and the other end goes to the ground of ecu?
