Section052–TEC ENGINE MANAGEMENT
Subsection 02 (COMPONENT INSPECTION AND ADJUSTMENT)
When installing new CPS apply Loctite 5910 be-
tween CPS and crankcase.
Torque to 8 N•m(71lbf•in).
Reinstall remaining removed parts.
AIR TEMPERATURE SENSOR
(ATS)
A33I0IA
1
1. Air temperature sensor (ATS)
Resistance Test
Disconnect the plug connector from the ATS and
check the resistance of the sensor itself.
Refer to TEMPERATURE SENSOR TABLE at the
beginning of this section to find the corresponding
resistance value for this sensor temperature.
If out of specification, replace the sensor.
If resistance tests good, reconnect the ATS and
disconnect the connector DA 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.
NOTE: Check if wiring harness shows any signs
of scoring prior to replace the ECM.
If resistance value is incorrect, repair the connec-
tors or replace the wiring harness between ECM
connector and the ATS.
Replacement
Disconnect the connector of the ATS.
PulltheATSoutoftheairintakesilencer.
Follow this procedure to install the ATS.
First, install the ATS rubber ring.
NOTE: If the rubber ring is installed on ATS sensor,
remove it before ATS installing.
Spray soapy water on ring. Install ring on air intake
silencer then push the sensor in place. Reconnect
it.
COOLANT TEMPERATURE
SENSOR (CTS)
Resistance Test
Disconnect the plug connector from the CTS and
check the resistance of the sensor itself.

The resistance between pin 1 and 2 is used for
temperature gauge.
Refer to TEMPERATURE SENSOR TABLE at the
beginning of this section to find the corresponding
resistance value for this sensor temperature.
If out of specification, replace the sensor.
The resistance between pin 3 and 4 is used for
ECM.
