MANIFOLD AIR TEMPERATURE
SENSOR (MATS)
PTO SIDE THROTTLE BODY
1. Manifold air temperature sensor (MATS)
Resistance Test
Disconnect the plug connector from the MATS
and check the resistance of the sensor itself.
The resistance should be between 2280
Ω
and
2740
Ω.
Otherwise, replace the MATS.
If resistance tests good,
reconnect
the MATS and
disconnect the AMP plug connector number 4 on
the MPEM.
Using a multimeter, recheck resistance value be-
tween terminals 16 and 19.
If resistance value is correct, try a new MPEM. Re-
fer to MPEM REPLACEMENT procedures else-
where in this section.
If resistance value is incorrect, repair the wiring
harness/connectors between AMP plug connec-
tor and the MATS.
Replacement
Remove the air intake silencer.
Remove the air duct.
Disconnect the connector of the MATS.
Pull MATS out while turning right and left.
Install the new MATS.
Reinstall remaining removed parts.
WATER TEMPERATURE SENSOR
(WTS)
1. Water temperature sensor (WTS)
Resistance Test
Disconnect the plug connector from the WTS and
check the resistance of the sensor itself.
The resistance should be between 2280
Ω
and
2740
Ω
.
Otherwise, replace the WTS.
If resistance tests good,
reconnect
the WTS and
disconnect the AMP plug connector number 4 on
