CANBUS Issues
I am at this point grasping at straws trying to figure out what to do next with my car. I haven't seen a whole lot of post regarding this trouble code.
2006 350Z Touring A/T
Vortech Supercharged Tuner kit, Uprev tune, with no issues for over two years until I had my radiator replaced a couple of years ago - this is not a daily driver, so this has been going on for a bit. After the radiator replacement I noticed my horn stopped working, then not too long after I started getting Bank A cam sensor signal error codes P-0340 combined with CANBUS fault, no specific code for this verbiage, just CANBUS. I went thru several sensors, but the Bank A cam sensorC/ANBUS error would come back after the car had been driven 20 minutes or so, especially after driving it, parking and then it would throw the code immediately on start-up (TCS off/SLIP) and if it doesn't do it on startup, it would definitely so it when it's dropped into gear. I put in a Stillen grounding kit in, and the car actually went without throwing a code for about a month...until it did again. The car has been pretty much undrivable and in the garage the last couple of years. Thinking perhaps I had damaged or frayed wires somewhere, I purchased a used engine harness from a wrecked 2006 A/T , just got it back last weekend and like usual, after driving it a while, turning it off, the same exact code came back when I went to start the car again. I'm not technical at all so sorry for the long post and poor explanation, and I may have not provided enough information for any comments. I'm starting to wonder if the horn not working could be the culprit, I think it is on the CANBUS, but I've also been told I should get another ECU. The harness installers forgot to check the horn but are going to be going back in to look at it this weekend. Rather than continue throw parts at it I thought I would see if anyone has had similar experiences. Hopefully I'll know a bit more if/when the horn issues get sorted out this weekend but I'm pretty jaded at this point and not holding my breath.
If anyone cares to chime in, I'm all ears, thanks for taking time reading this and any ideas in if you have any thoughts on it.
