The problem started on the previous week. I've started the car in the morning and left it idle just for awhile to close the garage doors. When I returned there were 3 errors on my dash: VSA, the exclamation and CEL. I restarted the car and VSA with the exclamation went away. I phoned my mechanic immediately and went to read the code. It was P0341 (camshaft position sensor). He cleared the code and told me to return if this happens again.
And it happend =(. The next morning the situation was the same. I phoned him again and he told me, that VTEC actuator was needed to be replaced probably. I didn't have 200$ that day and did this only after 4 days. CEL was always on and never disappeared from the dash.

I've checked acurazine for the info and was afraid that this is going to be chain replacement (I have a 04 with 170k+ miles which is burning oil) but after the replacement of VTEC actuator the problem disappeared. I didn't change anything connected with the chain, no tensioner, arms or smth.

This is the first time I hear this as a solution to this code.

That is why I named the thread as "New solution" =)
My mechanic also told me, that I wasn't the first. He had already repaired his TSX the same way a half of a year ago and a couple of Hondas CRV later. He had no problems since then (his TSX has around 120k miles but CRVs had less miles on them, around 60k or so, so this problem may relate not only to high-milleage cars).
Replacement of a single actuator is definitely cheaper and easier than replacing the chain, tensioner and arms.
Also, when I had this code I have had noticed that my car was accelerating a bit weird. It was because VTEC-actuator couldn't turn the camshaft in the right position in right RPM range. It was jamming in different positions making vtec not to work as intended (our vtec system works not only after 6000+rpm, it has multiple steps of engagement).

Hope that this information will save some money for some of you, guys.

I have the same problem replaced camshaft sensors and the vtec actuators. we even replaced the throttle body still pulling the same codes.very frustrating not sure what to do from here anyone have any ideas. 2004 tsx has 70,000 miles im original ower.
