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 CTS.
Replacement
Drain cooling system.
Disconnect CTS connector and remove CTS.
Install the new CTS and torque to 12 N•m
(106 lbf•in).
Reinstall remaining removed parts.
Refill engine coolant and bleed cooling system.
Refer to LIQUID COOLING SYSTEM section.
AIR PRESSURE SENSOR (APS)
A33E0RA
1
INSIDE LH SIDE PANEL
1. Air pressure sensor (APS)
Ensure sensor is correctly installed on air intake si-
lencer. Otherwise, the APS could generate a fault
code. Remove sensor and check for oil or dirt on
its end and if problem persists, check the wiring
harness. Perform the following tests.
Voltage Test
Check the voltage output from ECM to the APS.
Install the tether cord cap, turn OFF engine cut-out
switch and push START/RER button momentarily
to activate the ECM.
Disconnect plug connector from APS and connect
avoltmeterbetweenpin1and2ofwiringharness.
Voltageshouldbe5V.
Check the continuity between pin 3 on
APS con-
nector and pin 18 on ECM connector.
If tests are good, replace the APS.
If tests are not good, continue to check the conti-
nuity of the rest of the APS circuit on the harness.
Disconnect the connector A from the ECM.
Using a multimeter, check continuity of circuits as
per following table.
CIRCUIT NUMBER (ECM
CONNECTOR A)
APS CONNECTOR
A-3 PIN 1
A-4 PIN 2
A-18 PIN 3
If wiring harness is good, try a new ECM. Refer
to ECM REPLACEMENT procedures elsewhere in
this section.
Otherwise, repair the connectors or replace the
wiring harness between ECM connector and the
APS.
Replacement
Disconnect APS connector and remove the APS.
The ATS is retained with a screw.
Install the new APS.
EXHAUST GAS TEMPERATURE
SENSOR (EGTS)
A33I0JA
2 1
1. Muffler
2. Exhaust gas temperature sensor (EGTS)
Resistance Test
Disconnect the plug connector from the EGTS and
check sensor resistance.
