AIR FUEL RATIO MODULE
Refer to the Air Fuel Ratio Module Installation and User Guide (P/N 98200062) for
proper operating and maintenance procedures. Failure to follow proper procedures
may result in inaccurate data or damage to the equipment.
The sensor and the copper sample tube are hot. Before touching the
sensor or the sample tube, make sure it has cooled.
Leaded racing fuels and two-stroke applications will contaminate the
sensor and dramatically shorten its service life.
The sensor is not covered by a warranty. Be sure to read and understand
the Air Fuel Ratio Module Installation and User manual.
Before turning the pump on, verify there is no water in the hose.
Warm up the vehicle before placing the copper sample tube in the exhaust
to avoid drawing excess water through the pump assembly.
Keep the air pump assembly upright. Tipping the pump assembly may
result in damage to the sensor.
Leaks in the system will result in erroneous readings. Verify there are no
cracks or holes in the hose. Verify the sensor is seated properly in the
sensor block.
To ensure accurate readings, pump maintenance should be performed
every six months, or sooner, depending on usage. Refer to the Air Fuel
Ratio Module Installation and User Guide for more information.
