Replacing the Oil Level Probes

The oil level probes monitor the oil level by temperature differences. If they becomes disabled, the display shows: “E-18A”= left probe; “E18-B”= right probe; “E18C”= both. Also, if any of the probes are out of calibration more than 10°F, or 10°C, the probe should be replaced. An Ohm check can be performed also.
