Its in the lower intake manifold by the thermostat. No where near the EGR and I don't know the newer setups but mine always have 2 sensors. One for the ECM and one for the gauge. I think yours is a 3 wire and sends to both. If the ECM doesn't get a temp reading, it will screw with fueling and spark. The EGR isn't on until a certain temp either or a time frame base on start up coolant temp (going off OBD1 experience).
