I have a 2001 f 250 7.3L. As I was driving yesterday the engine stopped and would not restart. It turns over but does to fire. It felt like someone turned a switch off. I took the codes from my superchips they are p1670, p1316, p1212. Can anyone help?

P1670 EF Feedback Signal Not Detected
P1316 Injector Circuit/IDM Codes Detected
P1212 ICP Voltage Not at Expected Level

I would check your UVC harness on both sides. Do you know if these are old codes or just from this failure? Do you have a spare CPS? You should, I would throw a new one in and see what happens, they are less than $30 at Ford, buy two as you should always have a spare with you. If the CPS is good, and the harnesses look good and the connections are tight look at the ICP connector and see if it has oil on it, if so it is shot and needs replacing.
