Oil Level And Temperature Sensor
WARNING: This page is about a different variant/trim than selected.
The 3.0L V6 diesel engine is not fitted with a conventional dipstick. The dipstick is replaced with an ultrasonic oil level and temperature sensor which is located on 3 studs in the underside of the oil pan and secured with 3 locknuts.
The sensor uses ultrasonic pulses to determine the oil level in the oil pan. The sensor outputs a Pulse Width Modulation (PWM) signal to the Powertrain Control module (PCM) which converts the frequency of the signal into a oil level height.
The sensor uses an Negative Temperature Coefficient (NTC) type sensor to determine the oil temperature. The sensor measures the oil temperature and converts the sensor signal into a PWM signal to the PCM which converts the frequency of the signal into an oil temperature.
