Good Morning !
You guys have helped me before and I thanked you with some cyber beers!
I have a 2001 f350 that died on the freeway on my way to work. It has had some cps sensors before. And I always had a code for them. Now I dont know what code "1670 ef feed back signal not detected" . Any help would be great.

Thank you! Even my pricey Modus shows the code but not in the troubleshooter. In injector buzz test mode... nothing happens, as in no activity from the idm. I think I will bite the bullet and buy a new idm or a rebuild. Thank you for your time, and I will let you know what happens next!

you did a injector buzz test and nothing happened, does it smell like burnt wiring under the hood. i think mine did that code before when my idm went down and it just shut down the left bank, hade to replace the idm. after i checked all my wiring. ebay has the best deals on them as ford wants almost 800 for one

Thank you!
I bought a cheap rebuilt IDM from a rebuilder ( 300 ) it lasted about 10 minutes. So now I bit the bullet and got one from ford. Its been running ever since!
