Hey everybody I am getting these two codes lately, the P0575 hasn't been troublesome but the P1682 has been, before I supercharge swapped my 2008 2.4 I had no cel's but after my first start up I still didn't receive any, it was upon turning off that I noticed a difference in behavior, it seems as if the car pauses before shutting off now and this is when it trips the P1682 code. Electrically this is what has changed: 2.5bar map, 60lb injectors plug n play wiring, new spark plugs, I am using the LE5 throttle body so no change there, the iat wire has been moved to the 2.5 map, and the inter cooler pump has been wired to the the abs key on hot wire. I think it's kinda of odd that I get this error after the first start up with the blower on but never had a problem before? Also I still have my trifecta cable n goodies yet? Any ideas? I heard it could be the abs wire hook up?

Thanks

 

Alright I have a fix for this problem. When I wired my intercooler pump to my ABS switched wire I effectively wired in a small generator when the key is turned off. Since the pump motor is DC it will generate voltage back into the electrical iginition circuit for a brief moment, because the motor impeller does not stop instantly. This breif introduction of a voltage back in the ignition ciruit causes the car to keep running briefly after you turn the key off. Also triggers the P1682 Code because it generates a > 9V Back into the circuit. If you have this problem after install, buy a relay harness kit and install it. Fixed all my problems and now the car shuts down instantly when the key is turned off.
