Question type: Maintenance & Repair
My Nissan has had this code thrown for over a year. Eventually it resulted in a 2k replacement of the timing chain and other parts. The code was thrown a few weeks ago and my mechanic said he couldn't find anything. About a week ago the code threw again and using the service manual I've established that pin one of the CMP sensor is getting 12V instead of 5V and from there I have no idea what to do next.

To clarify, and I appreciate the concern, I'm not "winging it" here I'm working off the service manual. My problem is that it states to check the voltage at pin 1 of the connector to the sensor and if it isn't 5V then it says "repair open circuit or short to ground or short to power in the connector or harness" I'm fairly sure 12V qualifies as a short I'm looking for advice on how to find the short.

When I load up the page to view your second answer I can't see it here but I find it much more helpful. The original answer came off a little flippant but the second answer was much more helpful. (Ed92626) answered your question: "You're working off a service manual. The manual will show you just enough to get you into trouble; it gives you just enough information to motivate you to do the work for yourself. Your situation is something in the ECM. You'll search for a short that might be in a wire/connector leading to the ECM or in the circuit in the ECM itself. That's all the manual will give you. When you search, you run the risk of shorting out a good ECM. A trained mechanic has the equipment & expertise to avoid this. Your choice, but the hundred bucks you spent on the manual, that will give you good information for tune-ups and minor repairs, might lead to damaging a thousand-dollar ECM. Really, I'm trying to look out for you..... I'm 72 years old and still involved in TG3 and GT4 racing. Some of my time is spent on this site having fun helping people like you, and I'm not paid for doing this: I'm not making a dime off you." I at the very least wanted to establish that I had at least found the trail of the problem and ruled out some things because finding a "good" mechanic is exactly the challenge and I didn't want to take it in and have them throw the third new VVT Solenoid in, clear the code, and me end up back a month later. I would ask one more question of you though. I was thinking I may be able to remove the harness and at least check if there was a problem with that, would you say that that is not even worth it?
