Jeep 4.0 Cam Sensor connector or pigtail

If it is a Hall sensor it might need a pull-up. Typical Hall sensors have an open collector output, that goes low when metal target is present. The PCM, may provide pull-up. With PCM powered check the voltage at sensor input.

Pull-up value 3.3k is typical. The open collector helps with universal applications. The Hall power can be 5V, collector pull-up to 5V, 12V or whatever, usually inder 60V. In interlock applications open collectors can be OR'd together. If bench testing, supply gnd, 5V, pull-up to output. Observe voltage w, w/o target.

Voltage at the sensor input on the 411 ECU is zero with the ECU powered up. I'm thinking the 411 is going to be expecting a 12V square wave input signal for the cam sensor. There are some posts on a few websites that kinda support that thought but no one has come right out and confirmed it at this point.

The Ford CMP bolted right on the Jeep body as expected and the Ford is indeed a 12V input sensor and generates a 12V square wave (Hall Effect) output to the ECU. I was able to get the Ford connector at Fastman (Thanks Richard) So, I'm pretty sure I'm good to go. I've found no way in HP Tuners to confirm that I have valid Crank & Cam signals. So, I guess if it runs I've got em, if it farts perhaps not.
