AIR PUMP TROUBLESHOOTING GUIDE
Warnings
The sensor and the copper sample tube are hot. Before touching
the sensor or the sample tube, make sure it has cooled.
To avoid the risk of electrical shock, do not disassemble the
pump housing. No user serviceable parts inside.
Before assembling the filter, lubricate the threads on the filter stem
and filter bowl using the grease provided with the replacement
filters or a similar grease. Do not use silicone. The filter stem may
break if not lubricated.
Keep the air pump upright. Tipping the pump
may result in damage to the sensor.
Running the pump with the filter clogged,
hose kinked, or filter removed will damage
the pump and void the warranty.
Always allow the air pump to run for five
minutes, after the dyno runs are complete, to
allow the air pump to cool.
The Air Pump Assembly has a 90 day warranty.

System Check
Perform a system check before and after every

the sample tube, make sure it has cooled.
1. Cover the end of the copper sample tube with your
finger. The red warning light should come on in less
than three seconds.
2. If the warning light does not come on, there may
be a leak in the system.
Refer to the Air Fuel Ratio Module User Guide
for more information on finding and fixing leaks.
3. If the warning light stays on after removing your
finger (allowing air flow to resume), clean the filter.
4. Repeat steps 1-3 to confirm the warning light comes
on when you cover the copper sample tube with
your finger and turns off when you remove
your finger.
