turbogrill Posted April 23, 2017 Report Share Posted April 23, 2017 Hi The L28 engine has two engine temp sensors. One measures the coolant temp (contact with water) and the other measures the block it self with no water connection. The first was is connected to the gauge the other one is used by the ecu for cold start. Why have two? Why is the driver interested in the water temp and the ecu in actual block temp. Sensors have identical range and response. I am curious which one to log using MS. Quote Link to comment Share on other sites More sharing options...
