Section 06 ENGINE MANAGEMENT (SDI)
Subsection 03 (COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT)
If resistance value is incorrect, repair the connec-
tors or replace the wiring harness between ECM
connector and the ATS.
Replacement
Unplug ATS connector.
Pull the ATS out of the air intake silencer.
Spray soapy water on grommet. Install grommet
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.
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 CTS and
disconnect the connector A on the ECM as well
as the engine connector.

Using a multimeter, recheck resistance value
betweenterminals5and6onengineconnector.
This resistance 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.
Recheck also resistance value between terminals
11 and 27 on ECM connector A. This resistance is
used for ECM.
Refer to TEMPERATURE SENSOR TABLE at the
beginning of this section to find the corresponding
resistance value for this sensor temperature.
If resistance value is correct, try a new ECM. Refer
to ECM REPLACEMENT procedures elsewhere in
this section.
