"The OEM Oil Temperature Sensor is located at the front of the aluminum upper oil pan on various Nissan and Infiniti models equipped with a VQ37VHR. Special care must be taken when removing this sensor, as damaging the upper oil pan is easy when removing these sensors."
Yes the AA confirmed it was the sensor. The oil temp gauge danced wildly from start up and would not work at all sometimes. Then the engine management light came on. When AA plugged in the OBD2 is said faulty sensor weak signal. Many thanks. Dean
