05 civic 1.6 camshaft position sensor

[skoff]

Hi Honda gurus,

My wife has a 55 plate Civic 1.6 Sport EP3 that had a loss of power on the motorway and threw up an check engine light (static). I plugged my code reader into it and it gave code P0340 which is a fault with the camshaft position sensor.

I cleared the code, but the car displayed the warning light again after a short drive and cut power, so it's clearly not a one off.

My questions are -
Is it likely to be the sensor itself or is something more sinister likely/possible?

Is it ok to get a pattern part, or would you recommend Honda only?

The job looks pretty easy to do, are there any gotchas I need to worry about?

Thanks!

I guessing the Honda has variable valve timing. If this was working incorrectly, it might throw up a cam sensor code, and loose power / go into limp mode.
I'd normally go for an OE part if you are going to change it. (or OE parts suppliers like Bosch). If the part is cheap, it makes some kind of sense to change it rather than pay for diagnostics.

Thanks bearman68, the part from Honda was £82 so I've ordered one, if that doesn't resolve it than I think I shall send it in to the garage for a proper diagnostic.

I've changed the sensor now, and the code has disappeared, and no more CEL... However, the car will not rev above 4000rpm It is almost as if it is hitting the rev limiter. Any ideas anybody?

Oddly though, it only has the rev limit problem when stationary..? I have just driven it and it drives like normal.

do these hondas prevent you from revving above 4000rpm when stationary?

I now have to struggle with very little petrol and a virtually flat battery.

Facelift EP2 Civic's (i.e not EP3 Type R) came with a soft limit of 4000rpm when stationary, so yes perfectly normal.
