    Help with codes for an 02 Deville....

    These are the codes I have but I don't know what they mean?

    The car died when stopping at a stop sign and the Service engine soon light came on.

    U1714 - Loss of Front Door Module to Window Motor Normal Speed Comm
    B0429 - Temperature Control #3 Rear Circuit Range/Performance
    B1004 - Keep Alive Memory (KAM)
    P0385 - Crankshaft Position (CKP) Sensor B Circuit

    P0385 is telling you why you are stalling. Replace both crankshaft position sensors would be the best plan.

    Thanks, do you know how much that costs at a dealership?

    No idea as I do my own repairs as much as possible. Will be a warranty item if you are still covered.

    Thumbs up Re: Help with codes for an 02 Deville....

    Had exact same stalling/low speed problem and P0385 code set on 2002 STS with 30,000 mi. Dealer replaced both crank position sensors under warranty, problem solved. I watched the job, and sensors are not hard to replace if you can get the car high enough to work under easily. Look at other posts here and in "performance/technical" threads for online parts dealers if you're out of warranty, and for hints on replacement procedures. (A dealer will make a bundle on the recommended "flat rate" hourly cost to you.....) You're not alone.....About $50-60 apiece. Might as well change the oil and filter, too..... .
