1999 Sienna V6 Codes P0340

Hi Folks,

I am currently getting this code "Camshaft position sensor malfunction". I have gone through the various postings on this code and in most of the cases, it has happened when people have changed the timing belt. However, I have not done so (my van has only 116000km on it). I did change my sprak plugs and wires, but I was getting this code before the change. Any advise what could be the reason for this?

Thanks!

My coworker had the same issue with a 3.0L v6 Camry. His timing belt had not been serviced in a long while also, his timing belt was off one tooth. We re-timed it and all is well.
Thanks, my friend! Can you also please tell me how does it impact the engine performance? Can this work be delayed or should it be prioritized?

If the timing belt is off one tooth, that means that the intake & exhaust valves are opening too soon or too late which could result in power loss, rough idle, poor fuel economy. If it were my car I would have it addressed soon as possible because as to whatever caused it to jump timing could happen again resulting in catastrophic engine failure because if the timing is too far off the pistons will hit the valves.
