hi guys,
car made a big crack sound when staring, and since then the little car icon with the wrench is on, so the lump mode too (error code 340= camshaft sensor), and its limiting the engine to 4000 rpm
i cant find V6 camshaft sensor guide,  so where should i looking for it?  2.6 V6

The assumption here is that the sensor has failed...

Don't drive the car another inch until you've checked the timing.

The sensor is easy enough to change. But in this case it wouldn't be my first check.

If you do start with replacing the camshaft sensor, and again , I wouldn't under the circumstances, swap it with a known good one. From memory it can be replaced without taking anything else off. It's on the left hand cylinder head towards the front. Plug is next to it in the cable tray.

Good secondhand genuine one will be fine, but if you insist on getting a new one, then genuine or Bosch only. Don't waste your time on OE equivalent aftermarket rubbish.

I second Docs post, if the car made a horrible mechanical noise, then don’t even turn the key again until the timing belt setup has been checked.

Not just by peeling the cover back a bit, but by properly removing it, and checking the tension and timing is totally correct and no FOD

thanks guys
it was only one cracking like sound maybe it was just only the starter, because after that, the engine started normaly, sounded good, had the same power, nothing rattling sound, but i will check the timing
