Comes on at high RPMS. Just want to know more about it. Had the car dynoed and at 4700 rpms power just goes up and down. Wondering if its my opti going out.

Just want to know more waht that code means so i can fix the problem thanks guys.

 

Shoebox has a great site, including a list of the trouble codes:

Code 47 is your knock module

http://shbox.com/1/Dtcs.htm

 

So I'm assuming my knock module isn't working then. Put a lt4 KM in there probally 500 mils ago before winter.

Whats the exact method of testing?

 

Never mind just checked on shoebox site how to check it. only question which wire is D22 in the pcm?

Anyone else have this code ever throw?

 

keep looking on shoeboxes sire, he has the wiring pinout for a 95 on there

and D22 is connector D, pin 22

 

Found it, thanks for the help. ill be testing it tommorow mourning. Ill let ya know how the testing goes. I assume its the module though considering i put that lt4 in there before winter.

 

Pin D22 is for the knock sensor. Your problem (DTC 47) is with the knock module. Try reseating the module in the socket. Try replacing it with your stock module.

 

Well I tested everything anyway and all readings are in spec. Unfortially when i moved my stock module got lost. So im gong to have to pick up another lt4 one.

When that code comes on, useually at high rmps and my car bogs and loses power. So im hoping that will take care of it. If that doesnt solve the bogging on top maybe my opti is starting to show age. only 60k on it though.

 

As suggested above, reseat (remove and reinstall) you LT4 Knock Module to see if that fixes the issue before buying a new one.
