Hi everyone, I was just wondering if anyone had a wiring diagram for the gauge cluster connections? Thanks!

Get one of these

My battery connectors are pretty crap honestly, I’ll pick some up at Napa when I get over there this week. P0336, only code. It’s for the cam sensor. No other codes. Tested the sensor in another truck. It works great.

The code IS for the cam shaft, two different scan tools confirm that. however it’s not the sensor, mechanically the truck seems to be working just fine. Tested the sensor in another truck and it worked fine and dandy. Live readings give accurate information. I’m gonna pull the cluster out and check grounds and whatnot next

The ECM has an accurate reading of how fast the engine is spinning, so it leads me to believe it's else where. I think sensors are all good.... cluster test says the cluster is good as well.

2001 doesn’t have a crankshaft sensor, but ill double check anything at this point. edit: well I just looked and I can’t see anything that looks even remotely like a sensor. Aahhhhhh

Okay update. I took a visit to my ol man, and we pulled the sensor that we know is good out of one of his trucks (What a fight that was), and tried it in mine. Same problem! Also put my sensor in his truck and it works fine, so my sensor IS GOOD. I used one of those little dentist mirrors, like the ones they use to see the back of your teeth, and a flash light to get a look in the whole and the tone ring looked fine to me. What's interesting.... with the sensor unplugged, the tach still works for a few seconds before it conks out...? So, we checked wires, and voltages are the same across both trucks. So I need a new lead to follow! I read somewhere that if the PCM doesn't get a signal back from the tach, it'll throw it to zero? Maybe that's somewhere to look.

wiring seeeeeeems good, RPM is reported to ecm, so I’m thrown off completely, but it’s definitely worth a look. Thanks. Yes sir, of course.

it does throw p0336 or whatever it is for camshaft, two different tools tell me the same thing. It’s the only code, just baffled because it’s a new sensor in there. Though I don’t know how quality the part is, I’m going to try a known good one this weekend.

Yes sir, everything else seems to work as intended. Truck will run drive and charge for hours without problem. Just seems a little gutless and no tach.

Hi Everyone, I've got an 01 Drive-train that's doing a weird thing. First 5 or so seconds, the truck seems to idles a little high, and a little rough. Then it smooths out and sounds like its running fine, but it has to Tach reading. Completely drops to zero, this is consistent. Every time you shut the truck off and restart it, it does this. The tach even reads, while it does read, seemingly accurate. What else has me confused is when I plug the code reader in and go for a drive looking at live data, it also seems to report proper RPM. I did a cluster test and it didn't seem to have any issues, so I don't think it's a short with the gauge, the Cam Position Sensor is new, but I suppose could still be faulty. ECM is reporting RPM to diagnostics, although I'm not positive this data is coming from the CPS sensor. PCM wire 8 is also sending constant voltage across the wire. Here is a video of the issue
