Camshaft sensor wiring

Thank you Alex. These diagrams are extremely helpful and I appreciate it very much. So looking at c05 the camshaft connector on my car is sideways with the triangle on the left side. So I'm seeing it as 1 is the top wire. 2 in the middle and 3 is the bottom wire. So 12 volts to number 3. 5 volt signal wire to number 2. Ground wire to number 1. Is that right?

Okay. I had it hooked up wrong pretty sure I fried the new camshaft sensor. Got a new one coming in a couple days. Now I notice no spark coming from ignition coil for 2 and 3. There are two ignition coils. One does 1 and 4 the other 2 and 3. Power is going into both coils but no spark out from 2 and 3 coil. I switched the coils now no spark from same position coil. Could that be because I fried the new sensor? Someone told me I have to reset computer. Can I do that just by unhooking battery for 10 minutes or do I need computer to do that? Thanks

I did both tests that you mentioned. Battery is kinda dead so have it jumpered from my truck. Anyway after I did all those checks wiring is solid. Then I decided to check for signal pulse from the com to the ignition coils. On the good one I had dvom set to dc voltage. Crank the engine and middle wire to good coil jump to close to 5 volts. On the coil that isn't sparking that middle wire voltage does not change when cranking. So no signal pulse from PCM to that coil. So I assume the PCM has a fault in it. This cant be because of the bad camshaft sensor could it?

So about 3 months ago a couple different times the car died while driving and it had blown the fuel injector fuse and I replaced it. Bit then checked the injectors and wiring and absolutely nothing wrong with them. Now this is happening where one ignition coil is not getting signal from the PCM. Oddly enough at the PCM those are both in the same plug which means both running from the same chip inside the PCM. Pretty sure it needs to be replaced.
I took the PCM out of the car and cleaned all thr contacts on it and the wiring connectors plugged into it. With alcohol let it dry a day and plugged back in. Same result no fire to #2 ignition coil. So gonna replace it.
My ignition key does not have a chip in it and isn't programmed to the car. So would it be safe for me to buy another PCM same part number for same year car off eBay and replace it that way? Can get one for 50 bucks there. I don't want to put anymore into this car than that. Thanks

I replaced the PCM with used one off eBay. Exact same problem no signal to one coil. I unplugged wire harness under the hood right next to the wire harness for the crankshaft sensor. No signal there either. Back to square one I am gonna figure this out with the wiring diagrams hopefully. Just gonna replace the whole wire probably.

So I replaced the whole wire from the PCM to the ignition coil. Still no signal. On the wiring diagrams it looks like the wire goes straight from the PCM to the coil. Does it go through anything else? Maybe the PCM relay? I'm gonna give this car about 10 more minutes of my time and then roll it over the scales.

Wires going to the CMP on the black wires both had cracked insulation on them. I cut them back and replaced them. Then I plugged it back in checking voltage and pink wire had 12 volts. Number 3 black is ground. And number 2 black should be 5 volts but it read 12 also. Unplugged the connector and reading 12 5 and ground like its supposed to. Put first CMP sensor back in I bought new and plugged in and wires are all reading right now. Still no signal to one coil. On my car there is an ignition failure sensor. I replaced that a few months ago because the tachometer was not working. Checking those wires I noticed that both ignition coils get their 12v power through that sensor. There are 4 wires on it. One is power and one ground. One is for tachometer signal inside and the other is signal wire to the CMP which in turn tells it to send signal to each coil. So maybe that went bad it was a cheap part. So I bought another one off eBay and it will be here in a couple days.
After fixing the CMP wires cranking the engine it is way different wants to start but only one coil currently working. So hoping that its just that bad sensor and will let you know if it fixes it.

Talked to a friend of mine mechanic over 30 years. He said sometimes the wires just come loose in the connector. So I pulled it off and yeah a bunch of them loose. Got signal. Fired it up and timing belt broke. So it's going bye bye. Was a great car everything still worked, everything. So i'm a go shopping. What a mess.
