Inspection
1. INSPECT FRONT DIFFERENTIAL
(a) Using a dial indicator, measure the backlash of one
pinion gear while holding the front differential side
gear toward the case.
Standard backlash:
0.05 - 0.2 ...

Inspection
1. INSPECT MASS AIR FLOW METER
Visually check for any foreign matter on the
platinum hot wire (heater) of the mass air flow
meter.
OK:
There is no foreign matter.
If the result is not as specified, replace the mass air
flow meter.
Measure the resistance according to the ...

Hint:
The standard normal voltage between each pair of the
ECM terminals is shown in the table below. The
appropriate conditions for checking each pair of the
terminals are also indicated.
The check results should be compared with the standard
normal voltage for that pair of te ...
Installation
HINT:
Use the same procedures for the RH side and LH side.
The procedures listed below are for the LH side.
1. INSTALL FRONT AIRBAG SENSOR LH
Check that the ignition switch is off.
Check that the battery negative (-) terminal is
disconnected.
