5.4 Replenish the sensor oil
Inspect the oil in the sensor for large air bubbles during customer-scheduled service duty cycles.
Large bubbles can reduce the anti-fouling properties of the oil. Small bubbles (< ¼-in. diameter) do
not affect the oil properties.
To replenish the sensor oil, refer to the documentation supplied with the silicone oil refill kit. Refer to
