    Code p1502. Tops functional problem.....

    Working on an 05 RXT215. Ski was jumped off a running truck....

    Anyway, replaced MPEM (known good unit, used), and finally getting something from ski. I have checked all the fuses, and replaced the tops valve, tops sensor, and osps. Still getting code, and check eng light on gauge. Is it possible to be the ECU? I have checked each wire in the system for continuity, all good. Also inspected and cleaned each connector. Still nothing. Any ideas?

    Sounds like you have a pretty good idea what your doing, I would just double check and make sure your tops switch isn't upside down, sometimes it's dumb things like that that can make you pull your hair out
