When installed in the exhaust, the oxygen sensor must be connected
to a powered, functional PSB-1 (no error codes) whenever the
engine is running. An un-powered sensor will be damaged in a short
period of time when exposed to exhaust gas.
Do not pre-warm the sensor before starting the engine, start the
engine as you normal would. Allowing the sensor to pre-warm
before starting the engine will increase the possibility of damaging
the sensor from shock-cooling.
The maximum temperature of the sensor at the bung (the sensor
mounting location) should not exceed 500
o
C or 900
o
F. If these
temperatures are exceeded in your application you should install the
Innovate Motorsports HBX-1 heat sink bung extender. (p/n 3729.)
As the O2 sensor measures the oxygen content of the exhaust
gas to provide an accurate O2 reading, even a small pin-hole
leak in a poorly welded sensor bung will effect the accuracy
and performance of your O2 sensor. Remember, any deviation from the
instructions provided for proper sensor installation will lead to
inaccurate O2 readings
.
2.5.2 Sensor
Calibration
Once the unit has been wired and a suitable location has been found for both
the gauge and the sensor it is time to perform the sensor calibration.
Innovate Motorsports’ ‘Direct Digital’ wideband measurement principal allows
you to calibrate the sensor to compensate for sensor wear. This procedure
takes just a few moments and it will ensure the most accurate readings
throughout the oxygen sensor’s life. This procedure is required anytime a
NEW oxygen sensor is installed.
The calibration procedure requires that the oxygen sensor be in
free air
, this
means removed from the exhaust system completely.
1.
With the
sensor disconnected
, apply power to the PSB-1.
Confirm that the top right-hand corner viewport displays “O2 E2.” This is
an error code, indicating that no sensor is detected. Leave unit powered
on for a minimum of 30 seconds.
2. Power
down
the PSB-1 and attach the oxygen sensor using the cable
provided. When making these connections, make sure they are fully
seated and locked. Again, make sure that the sensor is in free air (not in
the exhaust).
3. Power
up
the PSB-1.
