I'm am not guessing the issue is on bank 2, I'm telling you it is. Fault code P0348 is for camshaft position sensor 2. if you had fault code P0343, that would be sensor 1 (bank 1). Pretty cut and dry. If you want to check for short circuit to B+ on the signal line without the pin out box you will have to
A. disconnect plug from camshaft position sensor, Bank 2. Turn ignition on.
B. using a DVOM (meter) check to see if the signal line is shorted to B+, it should read 0 volts. If you have anything more than that, you have a problem within the wiring harness between senor plug and DME control unit, (chaffing etc...)

Unfortunately, the tool rental will Jake will not work because of time. He can only send them to me the week after Christmass and i need the car before that ....THANKS A LOT ANYWAY JAKE!!!
So, if I don't get this solve this weekend I will have to take it to a repair shop.
Dharn55...Can I ask you more details on your shade tree mechanic approach?
I do have the factory manuals, but they are really confusing to me. What do I have to disassemble to start the adjustment? From the manuals it seems that you need to disassemble half of the engine.![Mad](https://rennlist.com/forums/images/smilies/mad.gif)
If I understood it correctly, you said to remove the cap
Which sprocket are you referring to and how do i get acces to it?
In the meantime, can anyone tell me how much would charge a shop to do this? As much as i want to learn ...i need my car back running next week, so I want to be ready for plan B
Thanks

... So I loosened the bolts on the sprocket and then took out the pin on the crank pulley and used a socket to rotate the crank in the appropriate direction, you have to figure this out by which way the cam is off.Guesstimated how much to rotate the crank, retightned the bolts on the sprocket, returned the carnk to TDC and checked the end of the cam to see if the grooves wer straight up and down.

Porsche52 - I think you have bank1 and bank 2 mixed up. Bank 1 is the 1-3 cylinders, drivers side (in US) of car, front of car (transmission side) on the top near the green plug, and a real bear to get at. Bank 2 is the 4-6 cylinders, passenger side, top again near the green plug. To get at it you have to remove some misc stuff, maybe the AC compressor, I forget.

Dharn55, can you specify which sprocket are you refering to. Please, check my previous post with your quote. Thanks
Porsche52, this means that is the code is P0348 I will only have to check/adjust the timing on bank 2 and not touch at all bank1?
Thanks

When standing at the rear of the car, looking into engine compartment. Bank 1 (1-3) is on the left, the Bank 1 cam position sensor is next to the green cam plugs, right behind the main coolant hose (crank pully side of engine). Bank 2 is on the right, the cam position sensor for bank 2 is on the back of the engine (flywheel side). It is next to the green cam plugs as well, very close to the body cross member. The sensor reluctor wheel is on the end of the intake camshaft, (opposite of the sprokets and chains) On the early vario cam engine yes, the sensor wheel was located next to cyl #3 and #4 , this car they are by #1 and #6.

Ok, I will check the timing visually again and post findings....you might be right. I was just assuming that it would be much of a coincidence that the sensor or harnes started failing right at the same moment when i screw up in replacing the IMS cover. I assumed that a tooth jumped when i took the IMS cover without taking the tensioners and that was triggering the code...but maybe I am lucky and it is just the sensor.
I will report back...THANKS

Wow, just read through the service manual for the 3.6 VarioCamPlus and they are quite different. The positioning of the grooves on the non-driven ends of the cams is similar, the grooves have to be straight up and down, with the narrow side out when the related cylinder is at TDC, put there are more adjustments and different tools involved for the sprockets on the driven end. Sorry if I caused any confusion or problems.

Ok, this might be my personal record of stupidity.
Following Porsche52's advice, I checked the sensor on Bank 2 and I found that it was disconnected. I might have disconnected it when I took out the green plug ti check the timing the first time, and I completely forgot about it..
This is pretty embarrasing, but at least it was a cheap fix.
THANKS a LOT FOR ALL YOUR HELP....and CASE CLOSED
