Disconnect the connector of the air temperature
sensor.
Using a multimeter, check the resistance be-
tween both terminals.
The resistance should be between 2.280 kΩ and
2.736 kΩ at temperature of 19°C to 21°C (66°F to
70°F).
If not within specification, replace the air temper-
ature sensor.
NOTE: As an alternate method, the resistance of
the air temperature sensor can also be checked
through the connector no. 4 of the MPEM follow-
ing this procedure.
Disconnect the AMP plug connector no. 4 on the
MPEM.
Disconnect the connector of the air temperature
sensor.
Using a multimeter, check the resistance of the
BLACK/WHITE wire between the AMP plug con-
nector (position 6) and the air temperature sensor
connector (terminal 1).
Check also the resistance of the WHITE/GREY
wire between the AMP plug connector (position
13) and the air temperature sensor connector (ter-
minal 2).
If there is an open circuit, repair the defective wire
or terminal. If not, proceed as follows to test the
air temperature sensor.
Connect the air temperature sensor connector.
Check the resistance between the BLACK/WHITE
wire (position 6) and the WHITHE/GREY wire (po-
sition 13) in the AMP plug connector no. 4. De-
duct the total resistance value of the wires.
If not within specification, replace the air temper-
ature sensor.

1. Water temperature sensor (WTS)
Disconnect the connector of the water tempera-
ture sensor.
Using a multimeter, check the resistance be-
tween both terminals.
The resistance should be between 2.280 kΩ and
2.736 kΩ at temperature of 19°C to 21°C (66°F to
70°F).
If not within specification, replace the water tem-
perature sensor.
