Resistance Test
Disconnect the connector from the MATS and
check the resistance of the sensor itself.
The resistance should be between 2280 and
2740
at 20°C(68°F).
Otherwise, replace the MATS.
If resistance tests good, reconnect the MATS and
disconnect the ECM connector A on the ECM.
Using a multimeter, recheck resistance value be-
tween terminals 7 and 21.

If resistance value is correct, try a new ECM. Refer
to ECM REPLACEMENT procedures elsewhere in
this section.
If resistance value is incorrect, repair the connec-
tors or replace the wiring harness between ECM
connector and the MATS.
Replacement
Disconnect the connector of the MATS.
Screw MATS out and install the new one. Torque
to 18 N•m (159 lbf•in).

Resistance Test
Disconnect the connector from the CTS and check
the resistance of the sensor itself.
The resistance should be between 2280
and

at 20°C(68°F).
Otherwise, replace the CTS.
If resistance tests good, reconnect the CTS and
disconnect the ECM connector A on the ECM.
Using a multimeter, recheck resistance value be-
tween terminals 11 and 27.
