1. INTRODUCTION
(a) This section introduces ways to determine whether
the run-flat tire is repairable or not. Repair must be
performed by following the appropriate procedures.
If a flat tire occurs, it is possible to drive a maximum
of 160 km (100 miles) at a speed below 90 km/h (55
mph) due ...
Inspection
1. INSPECT CRANKSHAFT POSITION SENSOR
Using an ohmmeter, measure the resistance
between the terminals.
Standard resistance
NOTICE:
"Cold" and "Hot" mean the temperature of the
coils themselves.
"Cold" is from -10C (14F) to 50C (122F ...
Inspection
1. INSPECT VANE PUMP SHAFT AND BUSHING IN VANE PUMP FRONT HOUSING
(a) Using a micrometer, measure the outer diameter [a]
of the vane pump shaft with pulley.
(b) Using vernier calipers, measure the inner diameter
[b] of the vane pump front housing bushing.
(c) Calculate the oil clearance ...
