jones57 Posted August 23, 2009 Author Report Share Posted August 23, 2009 well I went up and down on the temp. and disconnected the passenger dual control and it worked. Hopefully I dont have to fix anything. I have another code PCM p1520? Link to comment Share on other sites More sharing options...

Seanmannino Posted April 21, 2010 Report Share Posted April 21, 2010 I know I am digging up an old post here but I did a search on this code because it has reared it's head on my caddy. It was in History, and I think I know when it was thrown if my searches are leading me in the right direction. Is this a code to be really seriously worried about? From the searches I have read it could indicate that the shift lever was mode while the vehicle was in motion (which I did while coming down Floyd Hill in Colorado I shifted from OD to 3rd. The car didn't make any noises or hasn't been driving weird. Any ideas? Thanks ALL! Sean M. 1997 Cadillac DeVille Link to comment Share on other sites More sharing options...

I am shooting in the dark here... but I do not believe that moving the gear selector from OD to 3rd has anything at all to do with that code. I have did that too many times to count. I go to Colorado a couple of times a year... and I use my transmission, constantly, for braking going down the mountains. (I also sometimes use it in town ... when exiting the freeway on to the service road.) I am just speculating here... but I think the code means that the PCM isn't sure what gear it is in or should be in. Hopefully someone with more knowledge of "THAT" code will chime in here. I am curious now, to know exactly what it means. Link to comment Share on other sites More sharing options...
