Cheap Cr-v with engine management light

[underwhelmist]

I've been after a CR-V to use for shed duty and to practice my developing mech skills. There's a cheap one nearby, 2002, 120k miles, with the engine management light on. Apparently the fault code is about the cam position sensor. It seems to have been well maintained otherwise.

It's a chain driven cam and from what I've read there's a chance that this indicates a stretched cam chain. I don't think I'd tackle cam chain replacement myself. Are there any other likely causes of this fault code and would you take a chance on it?

Thanks for the information. I've decided to leave that particular car alone and instead I've gone for a well looked after generation 1 car, I reckon with some careful prep I might be able to tackle a belt change.
