Code 28 & 43
My check engine light comes on for a few minutes and then goes out. The fans are both stuck on all the time. The car will run fine, then the dash light blink like there is a short, and it will run rough. I'm getting a 12, 28 and 43 error codes. I read up on what the codes are, but don't understand where the problem would be. Anyone run into this before. Any help would be appreciated. I've driven it around the block a couple times, but that's all since this started before Christmas.
Thanks
Jim

Re: Code 28 & 43 (jstkrsn)
Well hey, you've checked the codes, sounds like either a sensor or ECM, the sensor is cheapest, check, you should have 18 Ohms-if you do-ECM failure. :confused: I haven't had this problem (YET) but that's where I'd start.
Good Luck & post your findings-come on :grouphug: guys, chime in :yawn:
