    3 weeks ago while idling my car for an hour to keep the woman warm my engine started to run funny. I pulled the code and it was code 10 IAT (JDM PCT ctr ecu), so I reset the computer and the code pops up right as it tries to run open loop. I tried 2 different sensors from a buddy's motors and I still throw a code.. So today I hooked up my old p2p(d16y8 ecu) and it only throws a ckf code (my b16 doesn't have one, the y8 does), no IAT code!?!?!?!? So I'm assuming i have a bad input in my pct ecu? the voltage at the IAT plug is 4.95vdc to ground at one wire and 4.95vdc to positive batt terminal..

    Also, the sensor i originally pulled out had a crack through it, so i have a new one installed..

    anybody had this crap happen before?

    You never know this used ECUs. I only buy ones from my tuner.

    Ended up being the wiring, I ran 2 wires from the Ecu and no cel's.
