Hi there, I would really appreciate some help please.

My Honda CR-V 2002 broke down a month ago after having some issues for a few weeks before. Just before breaking down it had no power, would start and then after a while conk out/stall and if I reduced my speed at all or stopped, it would conk out too. The AA ran a diagnostics on it on the ride side and sent me the report which had 4 error codes including camshaft and crankshaft sensors. I have replaced both the camshaft position sensors and the crankshaft sensor and now 3 of the codes have gone but there is still one remaining - the camshaft position sensor (despite replacing them!!).
I’m just wondering if the 2 camshaft sensors are actually the same or do I need to get another part/sensor for one of them?? Also, which one is ‘A’ and which one is ‘B’?
Also, if I buy another sensor and that doesn’t work, does anyone know what else it could be??
Thank you in advance, Take care.
