Hey guys - similar thread to my old one, but I wanted to simplify -- is temperature, per the CTS, the ONLY thing that tells the ECU to go from open loop to closed? I had access to a Chrysler DRBII and was able to get operating temperature-range temps from the coolant sensor with the engine running, but it wouldn't come out of open loop. This rebuilt 2.5L has all new sensors, everything except the TPS, which tested out fine (new 02, CPS, CTS, MAP, MAT).
