NOTE:

In the table above, the terms "cold" and "hot" refer to the
temperature of the sensor. "Cold" means approximately -10 to 50°C
(14 to 122°F). "Hot" means approximately 50 to 100°C (122 to 212°F).

NOTE:

Some systems need to be initialized after the cable is reconnected. (See
INITIALIZATION ).

INSPECTION

1. INSPECT CRANKSHAFT POSITION SENSOR

a. Measure the resistance according to the value(s) in the table below.

Standard resistance

STANDARD RESISTANCE SPECIFICATION

NOTE:



Some systems need to be initialized after the cable is reconnected.
(See INITIALIZATION ).



After the ignition switch is turned OFF, the navigation system
requires approximately 90 seconds to record various types of
memory and settings. As a result, after turning the ignition switch
OFF, wait 90 seconds or more before disconnecting the cable from
the negative (-) battery terminal.
