cam position sensors

Hello ,
I have code ,camshaft position aculator, is that the same as camshaft position sensors. I took the ones out at rear of engine , these are called cam pulse sensors, are these the same, dealer said there 4 , were are the other 2 located,also is there any way to check them.also is there any way to check coils, any help would be great
THANK YOU

front of the head..

2 for exhaust 2 for intake ..

car runs normal ?

if you have a "in line coil tester" you can test it that way

Hello Alpiaman24
Thanks for reply, Are they the ones located in front of block ,vano valves I took 2 out yesterday
Rt side,they were clean ,I put power to them ,they seem to work Ill do the other 2 tommorrow, are these the ones you ment?
THESE ARE THE CODES SHOWING
P0013-CAMSHAFT POSSITION ACULATOR B-BANK ONE
P0306-CYL 6 MISFIRE -I THINK THAT BAD COIL-?
P0507-IDLE CONTROL SYSTEM HIGH RPM
P0492-SECONDARY AIR SYSTEM
P0103-HIGH INPUT,

THE P0492 CODE &P0306 CODE JUST CAME ON, THE OTHERS I HAD I DID A SMOKE TEST
AND SMOKE SEEMED LIKE IT CAME OUT OF REAR BLOCK BY FIREWALL PASSENGER SIDE
I THOUGHT IT MIGHT HAVE COME FROM THE CAM PULSE SENSOR,I THINK THERE IS A VACCUM LEAK THERE,
THANKS AGAIN,

I think it means camshaft position actuators, the motors that drive the valvetronic, and not the sensors themselves. I maybe wrong!

Try swapping the coil on cylinder 6 and see of the fault moves, that will prove the coil.

yea i would say swap coils first

492 sounds lke evap code pointing toward purge solenoid in the engine bay driver side connect to the intake manifold going to a yellowish looking bomb filter change that and 492 goes away ..

as far as the smoke test .. did you put it in from the dip stick ? or from the filler neck or from the service port after you took the shrader valve out (reverse thread)

Thank you Alpina24 & Stuartiohn24 for your help,

i will check and replace coil, The first code said cam position actulator,I took to the dealer said it had a vacuum leak.but i could afford his price to find out were, The car drove good but idle keep going up and down ,never stalled. I did the smoke test throught the filler cap.the smoke chemical was empty so i didnt get much smoke out of machine,but did see a little smoke from back of motor by firewall passenger side, camshaft pulse sensor,dealer also said map sensor,
ONCE AGAIN THANK YOU
