    Always add the suffix to each code - Current or History. It makes a difference.

    U codes are voltage and data transmission hiccups.

    This link is in the proper year sequence in the "How to pull codes" sticky ^^^^

    Re: 2001 SLS. Need help with codes!

    Your engine has two CranKshaft Position sensors (CKP) - an upper and a lower, B & A. Pictures in my albums. Not fun. CKP codes are P 0335, P 0336, P 0385, P 0386 plus a few circuit codes.

    For codes and how it works ....... Suppose a fault is detected in CKP A - a code of P0335C sets. If the fault is a total CKP failure the engine defaults to "Limp Home" mode - fixed ignition timing, and you should get a SES light. BUT, if the fault is transient - a hiccup - then the code stays Current for 3 more ignition-run cycles even if the fault is not again detected. After 3 successful start-run cycles during which the fault does not appear the code changes to History, where it remains for 30 more start-run cycles, and if the fault does not appear during that time the code then self-clears from the memory. (Different modules have different numbers of checks necessary to self-clear codes from History)

    During a normal commuter/shopping week you will start/stop the car about 25 - 30 times, so it's entirely possible that a non-critical code could set on Monday morning, go to History, and be gone by next Monday.

    Many, many codes come and go like clouds - you get into a habit of "pulling codes" for no reason at all and you will go stir crazy trying to figure out where and why they all appear/disappear. I used to "pull codes" once a month and write them all in a log - after a year of that stupidity I quit. Haven't gotten into the system in over 2 years. No reason to.
