G11699195

The TDV6 3.0L 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 three studs in the underside of the oil pan and secured with three locknuts. A link lead connects the sensor to the engine harness at the right side of the oil pan.

The sensor uses ultrasonic pulses to determine the oil level in the oil pan. The sensor converts the results into 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.
