2 weeks ago I was driving on the freeway when I noticed that my CEL went on and my speedometer wasnt working. Couple minutes after that I started losing power...fist my radio went out and then my lights started dimming. Pulled over..car idled for a couple minutes and then died. I replaced the battery and alternator and the started up and hasnt died since. My CEL light is still on and my speedo still didnt work. I had a code 20 and 41...electical load detector and heater in the primary O2 sensor. Put in a used o2 sensor and that didnt work. And i also noticed that I keep blowing the fuse to the alternator/SP sensor. Any advice that you guys could give me would be awesome..thanks.

 

Think I just found the problem

Correct, The ELD will dectect a high/low voltage due to the alternator failing. And also that intern makes the o2 sensor get the incorrect voltage. But also, check for any shorting in the wiring harness.
