Hey guys, been awhile since I've posted last. Looking for advice. I've had the p1633 code on my dash for over a year now and it causes no issues, but I'm getting tired of staring at the engine light lol. Checked all 3 pwm and Kam fuses, all check with no resistance. So I followed the wire going from the Kam fuse to the vehicle computer, cut a small portion and tested. I was getting 7.5 ohms resistance between the ground and the 3rd wire from the bottom right of the middle connector. So I cut the wire, and ran a new one to ground. Now measures with 0 resistance as it should. But the engine light still persists, and I am out of ideas. Any suggestion would be greatly appreciated. Thanks, Aaron
 
Could be a bad Dash cluster, or cluster computer....
 
Ford scan tool only I believe..... I know my black 10 has the dash issue.... It looses the settings and MPG and trip all the time.... So I stopped using that..... Just not worth fixing in my book for me..
 
Well as life has it, I may have to sell the Trac soon for something good on gas.... So if I do I'd like to have no engine lights on, people tend to be Leary about them...
