3. INSTALL TAILPIPE ASSEMBLY
(a) Using a vernier caliper, measure the free length of
the compression spring.
Minimum length:
38.5 mm (1.516 in.)
If the length is less than the minimum, replace the
compression spring.
(b) Install a new gasket by hand so that its surface is
flush with the center exhaust pipe.
NOTICE:
• Make sure the gasket is facing the correct
direction.
• Do not reuse the removed gasket.
• Do not push in the gasket while installing the
tailpipe.
(c) Connect the 2 exhaust pipe supports, and install the
tailpipe.
(d) Install the 2 compression springs and 2 bolts.
Torque: 43 N*m (438 kgf*cm, 32 ft.*lbf)

ON-VEHICLE INSPECTION
HINT:
It is normal for the cooling fan to sometimes rotate when the
ignition switch is turned from ACC to ON.
1. CHECK COOLING FAN OPERATION AT LOW
TEMPERATURES (Below 94
C (201F))
(a) Turn the ignition switch ON with the A/C switch OFF.
(b) Check that the cooling fan stops.
If it does not, check the cooling fan relays and
engine coolant temperature sensor, and then check
for disconnection of the connector or a wire break
between the cooling fan relay and engine coolant
temperature sensor.
(c) Disconnect the engine coolant temperature sensor
connector.
(d) Check that the cooling fan rotates.
If it does not, check the fuses, cooling fan relays,
ECM and cooling fan, and then check for an open
circuit between the cooling fan relay and engine
coolant temperature sensor.
(e) Reconnect the engine coolant temperature sensor
connector.
2. CHECK COOLING FAN OPERATION AT HIGH
TEMPERATURES (Above 96
C (205F))
(a) Start the engine, and then raise the coolant
temperature to above 96
C (205F).
HINT:
Coolant temperature is the value detected by the
engine coolant temperature sensor on the cylinder
head.
(b) Check that the A/C switch is OFF.

DEFINITION OF TERMS
Te r m D e f i n i t i o n
Monitor description Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details).
Related DTCs Diagnostic code.
Typical enabling conditionPreconditions that allow the ECM to detect malfunctions.
With all preconditions satisfied, the ECM sets the DTC when the monitored value(s) exceeds the
malfunction threshold(s).
Sequence of operationThe priority order that is applied to monitoring, if multiple sensors and components are used to detect the
malfunction.
While another sensor is being monitored, the next sensor or component will not be monitored.
Required sensor/Components The sensors and components that are used by the ECM to detect malfunctions.
Frequency of operationThe number of times that the ECM checks for malfunctions per driving cycle.
"Once per driving cycle" means that the ECM detects malfunction only 1 time during a single driving cycle.
"Continuous" means that the ECM detects a malfunction every time the enabling condition is met.
DurationThe minimum time that the ECM must sense a continuous deviation in the monitored value(s) before
setting a DTC. This timing begins after the "typical enabling conditions" are met.
Malfunction thresholds Beyond this value, the ECM will conclude that there is a malfunction and set a DTC.
MIL operationMIL illumination timing after a defect is detected.
"Immediate" means that the ECM illuminates the MIL the instant the ECM determines that there is a
malfunction.
"2 driving cycle" means that the ECM illuminates the MIL if the same malfunction is detected again in the
2nd driving cycle.
Component operating rangeNormal operation range of sensors and solenoids under normal driving conditions.
Use these ranges as a reference.
They cannot be used to judge if a sensor or solenoid is defective or not.
