Default So Exactly Where is the VVT Controller?

Ok, so I am running out of ideas on my P1350 and P0340 code problem.

Nad1370 had mentioned the VVT controller as a possibility; maybe sticking on Bank 2.

So, is that the solenoid-looking valve on the inside of the "V" (manifold side) of the head at the extreme outer end over the starter?

Thanks!

Ah, the VVT sensor (camshaft position sensor). Let me show to photos that show bank 2.

If use an ohmmeter to check the resistance, the following should be the values:

835-1400 at cold
1060-1645 at hot

Oh, crap!

So in other words, the VVT sensor is actually the camshaft sensor? I already blew $70 on that part trying to fix this problem.

So which sensor can get stuck (senses oil pressure)? I didn't think it was THIS one? This simply looks like a prox switch, not a pressure switch.

There is what looks like a solenoid located right behind the yellow arrows, I thought that might be it.

Oh, and yes. I am sorry you had to do tranny work. From what I am hearing, that is becoming a recurring them on these cars.....not good.

Thanks!

I am not sure about the piece you are pointing out in yellow, but there are two camshaft sensors bank 2 on the front and bank 1 on the rear.

For the errors you mentioned above, they both relate to the bank 2, (either a short or a dead sensor). The sensor actually can be removed and examined.

Thanks for the reply.

I already changed the left side (radiator side) sensor. It was really easy to get to. That is supposed to be bank 2, but someone mentioned something about "how are your oil changes?" and that there is a sensor somewhere (I assume a rheostat or varistor pressure switch) that monitors the oil pressure and adjusts the timing according to the perceived load on the engine. They replied that is probably getting stuck at times.

So that was my question.

I called the dealer for an appointment; but he inspired NO confidence in their ability to fix the problem if it doesn't act up when they have it. So, basically, I know what is going to happen. I take it. It doesn't mess up. I go get the car. I pay $200 for the parking space in their lot for a day. And drive a broken car home waiting to screw me again out on the road like it has 3 times now.
