CP4 went out but it was not catastrophic. It started loosing power on an overpass. By the time I got off the overpass, exited highway, slowed to make U-turn, and pulled into parking lot, it was still running. Would not start after shut down.
Thankfully I installed a 'disaster prevention' bypass kit. Tiny bit of metal filings in the return lines/regulator on top of CP4. So far, I have removed bad pump, installed new CP4, flushed return lines, and installed new fuel filters.
The vehicle starts but runs extremely rough. Getting P0016 code as well as P228F. Looking at the camshaft sensor/timing issue first, I tore into the engine again and removed the sensor. Physically it looks fine, tested that it was indeed getting 5V power. Sensor output had a solid 4.64V and would drop to zero (and bounce back up) after putting it near something metal. Perhaps this doesn't confirm that it is fully functional but I have read this is the hall-effect response of a normal camshaft sensor. Using ForScan, the camshaft sensor channel shows zero activity. Is sensor bad because the output is not a full 5V?
This has me perplexed. Does anyone have any further troubleshooting ideas? Since the CP4 did NOT fail catastrophically, no damage to CP4 gear or camshaft gear - nothing looks out of place and I don't see how it could have jumped teeth. Even if cam is out of timing, it is still not providing a camshaft sensor reading. When I turn the CP4 gear by hand it turns the engine.
Vehicle is a '14 6.7 4x4 platinum with 262,000 miles. Running a DB Power stage 2 turbo, with EDGE tuner. Vehicle was deleted years ago. Thanks in advance for any suggestions. Let me know if I can provide any more details.
