Code P1600

[dsmdriverjeff]

Okay so I looked around and the only two posts I could find on the P1600 code never got answered and mine was a different situation, so basically I rebult my head because I bent valves, but now that the car is running it is very sluggish and seems fine in park or nuetral but when I put it in drive it drops in rpms and sometimes dies, when I drove it the car didnt idle forward and when I pressed the gas it rose in rmp's very slowly and didnt accelerate until the turbo kicked in around 3 rpm's so thats when I tested it and it threw the code p1600, so i pulled the tcm and checked for burnt spots or smells and couldnt find any and I dont know what else it could be? I've tried unhooking the battery and resetting the computer but neither of those worked, also when I rebuilt the motor I put an ecu in from a manual car, but I also tried switching back to my old ecu which is oem and its still not fixing the problem, is there a fuse or relay I could check?

A quick google search brought up pin 91 going to the ecu on a manual trans ecu needs to be grounded. The manual doesnt ground it through the starter relay like the auto ecu does.

thanks and I had actually found that a couple days ago and I put my old ecu back in and still the same problem...

Another thread I read said the TCM is keeping the car in third gear, it sounds like that is your problem. Maybe try and source a known working TCM and see if your problem goes away.

You might try getting ahold of Andre at Pina Motorsports or David at Boss Innovations and see if.they have one lying around.

 

[dsmdriverjeff]

Do you know them personally? Or do you have their numbers or anything?

Ive dealt with andre a few times in the past and has always been a good guy to me. David, I had him socket my ecu and the solder job has failed twice so far(hairline fracture). Other than that I can not comment on his abilities. Although I do hear he does pretty good work. Andres shop is out in kent off of 212th and west valley a little ways. The number
Is 253-872-9495
