First off I'm a first time user so sorry if I screw something up! I have a '97 f-350 psd and I think I am having a problem with the PCM. My truck sat in the driveway for a couple of weeks in the rain. One morning I started the truck and the wts light would'nt go off. About half way to work the wts light went off and the truck went into limp mode then died. I got it home (on the hook) and checked the gpr and everything works fine. I pulled out the PCM and water was sitting in the case. I dried it out and cleaned the contacts for my chip and put it back in. The truck seems to run fine, shifts a little funny and still no wts light. I had the codes pulled and i got a P0381, P0605, P1395, and a P0603. Can someone please tell me if reflashing the computer would fix the problem or do i need a new PCM?

 

Welcome! Do you have a friend with a powerstroke? If so try using his pcm and see if it helps. Also try driving with the chip unplugged. I dont think anything good comes out of them getting wet.

 

Thanks! I dont have any friends with powerstrokes and I pulled the chip and no difference. I pulled the bulb and checked the wireing and all seems to be fine

 

Sorry to have to post this ::::

• DTC P0605 exists only when there has been an internal failure of the powertrain control module (PCM).
• Rerun Scan Tool Diagnostic Test.

Is DTC P0605 retrieved?

Thats kinda what i was thinking. Do you guys know of where to get a fairly cheap one. I was thinking of maybe ordering one from dp tuner and do you know if a simple flashing would fix the problem
