Removal/Replacement Procedures Disassembly/Reassembly
5.
Disconnect air sensor connector(s) CN811 and/or CN812 from the CPU
board (Figure 11-7 , item 14 for Pump 1 or Figure 11-12 , item 14 for
Pump 2).
6.
Remove the screws that secure the air sensor to the pump head and
carefully pull out the air sensor assembly.
7.
If required, desolder and discard the green ground wire from the back of
the replacement air sensor assembly (Figure 11-7 , item 14 for Pump 1 or
Figure 11-12 , item 14 for Pump 2).
Note: Be careful not to disconnect the ribbon cable of the slide clamp mechanism
during this step.
8.
Insert the replacement air sensor connector through the air sensor
opening on the pump head and pull the wires all the way through.
9.
Solder the ground wire to the new air sensor.
10.
Secure the replacement air sensor to the pump head (tightening torque of
2 kgf-cm or 1.7 in-lbs) and reconnect CN811 and/or CN812. These
connectors are keyed.
11.
Route the wires to their original location and replace any cable ties that
were removed in step 2. The number of ties and their locations should
approximate the original configuration.
12.
Trim the ends of all newly added cable ties so that they are flush with the
cable tie buckles.
Note: If the ground wire screw was loosened in step 2, tighten the ground wire
screw to 7 kgf-cm (6.1 in-lb).
13.
Perform the calibration in “DC Line Voltage Calibration” on page 9-1
and “Air Sensor Calibration” on page 9-6.
14.
Perform the Operational Checkout procedures in Chapter 10,
“Operational Checkout”.
