'03 Almera crankshaft position sensor location

    Hi folks,

    I need to change the crankshaft position sensor on a family member's 2003 Nissan Almera (N16), but I can't figure out where it's located. I've changed the cps on a few different cars but never an Almera. I suspect it might be on the underside of the engine - can anybody confirm or possibly point me in the right direction?

    Cheers!

    Just in case anybody else is having the same problem:

    The CPS is about 6" above the starter motor on the back of the engine block, only really accessible from underneath the car.
    Disconnect the electrical connector (push-tab type) from the CPS, undo the hex-bolt that holds it in (size 13 if I recall correctly, though it could have been 10) and pull the CPS out. The one on this car was jammed in fairly tight due to the rubber o-ring swelling a little and it was hard to get an arm into the engine bay with the axle etc. in the way but keep at it and it'll come out eventually.

    It should also be pointed out that in the majority of cases where these N16 Almeras log a fault code for either cam or crank sensors the actual cause of the problem is a stretched timing chain rather than a sensor fault.

    Yep, the timing chain had to be changed last year for that exact reason, quite the design flaw! Checked the chain when I changed the CPS and it's fine (for now!!), but as you mentioned when people get a CPS circuit error etc. they should definitely check the chain too - only takes 5 minutes!
