    ckp sensor for STS2001

    My STS2001 has 109K miles and stalled twice in the last 2 months at low speed. I am changing the spark plugs and boots. There is npo code for ckp. I am not sure if I should change ckp sensore as well or see if car stals after changing the spark plugs or not. Also I see at rockauto that there are lower engine ckp and upper engine CKP. Do I need one each? CKP from standards is much cheaper than AC delco. Any idea about buying the cheaper one from Standards

    Thanks
    John

    Try cleaning the throttle body first.

    Your engine takes 2 CKP's - each different. Buy the AC Delco replacements (if necessary) and they'll fit and work correctly. I have no idea of which companies buy the DENSO (AC Delco) CKP's and re-brand them.

    More pictures in my albums and in RockAuto. Your best bet might be to talk to Chris in Parts at Rippy Cadillac tomorrow morning - over there >>>

    Zoom in on the picture - the part numbers are the second number from the bottom of each package.

    Being an '01 and randomly stalling with no DTC's points to CKP sensors. GM had a bad supplier from 2000-2003. Change them both. I did mine last summer and got them both on Amazon for $77 with free shipping.

    I think I may have the bad ones on my daughters '04 SLS. Hard to believe they have never been changed at 134K.

    Re: ckp sensor for STS2001

    CKP - Crankshaft Position Sensors - are a known problem -
    and failing units won't always set codes -

    as Ranger put it -
    "it's not IF they will fail - but WHEN they will fail" -
    ---------------
    don't use anything but the genuine ACDelco parts -
    here are the best deals I found -

    ACDelco 213-1578 - $37.97 - with free shipping -
    from amazon.com -
    http://www.amazon.com/ACDelco-213-15.../dp/B000C9JORO
    and -
    ACDelco 213-1579 - $43.19 - with free shipping -
    also from amazon.com

    so $81.16 for both - with shipping -
