VinhZXT Posted November 3, 2006 Share Posted November 3, 2006 Cho240Z, The coolant temp sensor I am talking about is the one in the front of the driver side's head. That sensor feeds the temp info back to the PCM. The PCM uses that to determine when to turn on your fan. If you removed that and put in another temp sensor so that your stock temp gauge will work then it will mess up your fan and possible how the engine runs in close loop mode. On my LS1 swap I left that stock temp sensor alone and installed another one in the JTR T fitting to get the stock temp gauge to work and the fan works fine. Without the stock temp sensor the engine will run OK but in open loop mode. Quote Link to comment Share on other sites More sharing options...

cho240z Posted November 15, 2006 Author Share Posted November 15, 2006 i replaced the collent temp sensor because it looked pretty done. still nothing. i still need to check the continuity from the sensor to the ecm. other than that i know all of the other wiring is good. luckily my azc radiator is enough for cooler weather Quote Link to comment Share on other sites More sharing options...
