Water Temperature Sensor (Wts) - Sea-doo RX Shop Manual

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.
Refer 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.

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
the MPEM.
Using a multimeter, recheck resistance value be-
tween terminals 9 and 11.
If resistance value is correct, try a new MPEM.
Refer 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 WTS.
Replacement
Remove air/fuel rail retaining screws.
Cut locking ties as necessary to allow lifting of
air/fuel rail in order to give access to the tempera-
ture sensor.
Disconnect WTS connector and remove WTS.
Apply Loctite 518 on threads of the WTS then in-
stall.
Reinstall remaining removed parts.
