Removal/Replacement Procedures Disassembly/Reassembly
7. Secure the replacement air sensor to the pump head (tightening torque of
2 kgf-cm or 1.7 in-lbs) and reconnect CN811.
8. 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 (refer to “Routing of Internal
Wiring” on page 8-33).

cable tie buckles. If the ground wire screw was loosened in step 2,
tighten the ground wire screw to 7 kgf-cm (6.1 in-lb).
10. Perform the calibration in “DC Line Voltage Calibration” on page 9-1
and “Air Sensor Calibration” on page 9-6.
11. Perform the Operational Checkout procedures in Chapter 10,
“Operational Checkout”.
