i extended my primary o2 sensor wire to the front of the header for my turbo setup on d17y8 civic ex 00. its a obd 2 with the 4 wire o2 sensor.

the extended wire got caught up in the drive axle and there for both side of the o2 to 1: to the sensor it self 2 to the engine harness. both ripped apart!! the adapter from the engine harness is gone too!! now when i try to connect them together directly w/o adaptor, the check engine light 41 is still on (car also in limp mode). anyone ever had this happened to them or know how to fix it?

ps any reason why my spedometer stoped work also?

 

Check the #15 fuse in the under dash fuse box. (I think it's a 7.5 amp.)

 

wow!! your right .. ima try to hook up the 02 wires now to see if it will work. and my air fuel gauge to see if it goes on now.
