Hey guys,

I'm sure this has been discussed many times, but hear me out.

Code P1688 Metering oil pump control circuit initial check problem

Got the silly engine light a few days ago randomly on a warm start, car went into limp mode, pulled over, turned it off for a bit, started it up again, engine light remained but limp mode disappeared. It was all okay cause I had the error erased until it kept frequently popping back up, and now my car's stuck in limp mode in the workshop (gay).

I've tried re-adjusting/re-calibrating the switch by loosening the two screws, turning it clockwise a bit, removing the battery (to reset the ECU, also easy way to access the switch), then starting the car up. Light still shows, repeated maybe 8 or 9 times and gave up since the engine was beginning to flood.

I was just wondering if there was anything I was doing wrong or just some basic advice on what I should do. I have SOME mechanical experience but my knowledge with rotaries is far from enough.

Thanks.

 

If you are getting a P1688 then you have/own a Series 1 2004-2008 RX-8, you have posted this in Series 2 Forums 2009-2011 (different set up)

This code does not apply to Series 2's..

You might get a quicker answer if you delete this thread and redo it in this sub forum.
