USING THE AIR FUEL RATIO AIR PUMP
The CPI allows control of the optional internal air pump that is part of the air fuel ratio
(AFR) sampling system. This air pump is built into the AFR module to draw exhaust
gases over the AFR sensor. The button on the control panel allows the dyno user to
turn this pump on and off. The indicator light on the control panel will illuminate
when power is provided to the pump.
If the pump does not run, check the following:
• Verify the switch on the pump assembly is on.
• Verify fuses F3 and F4 on the CPI board.
• If the E-Stop button is pressed or the external E-Stop circuit is open then the AFR
pump will not run.
Refer to the Air Fuel Ratio Module Installation and User Guide for proper operating
and maintenance procedures (P/N 98200062). Failure to follow proper procedures
may result in inaccurate data or damage to the equipment.
