I just installed my comptech SC and the car drives fine and it isn't in limp mode (hehe).. I ran modifry's DTC tester and it's 8 long blinks and 3 short blinks .. which isnt listed on his web page. The closest autozone is 30 minutes away and the prick at kragen wanted to charge me $40 to get the code even though its his own tool... which i actually agreed to but he kept helping other customers so i walked out after waiting 15 minutes.

anyone know what this code is? on modifrys site he has 8-4 listed as air valve low voltage but i'm 8-3 not 8-4... is it closely related?

edit: in an old search i found :

DTC 8-3 - internal failure of SRS unit

not quite sure where this fits in..

 

Right away I'd check the routing of the vac lines, and direction of the white check valve.

Blink 83 = P1415 or P1416. Air pump high or low voltage.

 

Got your pic VIA PM. The white check valve is in backwards. Post that pic here for the masses

 

when you mentioned in the first post that the valve could be in wrong i took it out and put it in the opposite way it was and reset the ecu and the CEL still came on after startin the car again.

then i took the pictures and sent them to you. i just changed it back and the CEL is still there after pulling the back up fuse for 60 seconds and restarting the car.

here was the pic of the wrong direction:




any other clue ? my vacuum lines are exactly put in per comptechs instructions. the car drives perfect.. just this CEL really bugs me and i'd like to fix it before it becomes a bigger problem.

 

did you hook up the aftercooler pump to the air pump?
If so did you hook it up? Did you connect it correctly?
Did you replug it back in?
I just finished the same install and had no problems.
Also is the ESM connected correctly WITH solder?

 

also what about that thingy that hooks up to those lines, did you reinstall that?
did you reinstall it correctly?

 

yeah the aftercooler pump is installed correctly, i can hear it running when i switch the ignition on.

the esm is connected correctly but its just put on with regular crimps. could that be whats causing this problem? i took the car for a quick but spirited test drive and it boosts just fine and no limping or any problems.


if you're talking about the air control solenoid valve and the air control valve vacuum tank yes its installed and hooked up correctly per the instructions.

 

Make sure the valve is in right, reset it, then pull the code again.

83 is an air pump code. If the code persists, then it's a fault in the air pump connections, due to the circulator install.

A backwards check valve usually results in a blink code 60. If you didn't show code 60 now, you would have shown it after two drive cycles.

 

Blink code 5 will show up if the ESM is having issues.

 

Almost forgot....clear the code, then turn the key on, DO NOT start the engine. Check for a code without running the engine.
