Diagnostic Procedure

UBS00DAO

1. 

CHECK COOLING SYSTEM FOR LEAK

Apply pressure to the cooling system with a tester, and check if the
pressure drops.

CAUTION:

Higher than the specified pressure may cause radiator damage.
Pressure should not drop.

OK or NG

OK

>> GO TO 2.

NG

>> Check the following for leak.

●

Hose

●

Radiator

●

Water pump
Refer to 

CO-10, "WATER PUMP"

 .

2. 

CHECK RADIATOR CAP

Apply pressure to cap with a tester.

OK or NG

OK

>> GO TO 3.

NG

>> Replace radiator cap.

3. 

CHECK THERMOSTAT

1.

Check valve seating condition at normal room temperatures.
It should seat tightly.

2.

Check valve opening temperature and valve lift.

3.

Check if valve is closed at 5

°C (9°F) below valve opening tem-

perature.

For details, refer to 

CO-13, "THERMOSTAT"

 .

OK or NG

OK

>> GO TO 4.

NG

>> Replace thermostat.

CHECK ENGINE COOLANT TEMPERATURE SENSOR

Check resistance as shown in the figure.

<Reference data>

OK or NG

OK

>> GO TO 5.

NG

>> Replace engine coolant temperature sensor.

5. 

CHECK MAIN 11 CAUSES

If the cause cannot be isolated, go to 

EC-444, "Main 11 Causes of Overheating"

 .

>> INSPECTION END

Perform FINAL CHECK by the following procedure after repair is completed.

1.

Warm up engine. Run the vehicle for at least 20 minutes. Pay attention to engine coolant temperature
gauge on the instrument panel. If the reading shows an abnormally high temperature, another part may be
malfunctioning.

2.

 Stop vehicle and let engine idle. Check the intake and exhaust systems for leaks by listening for noise or
visually inspecting the components.

3.

Allow engine to cool and visually check for oil and coolant leaks. Then, perform “Overall Function Check”.

DTC P1336 CKP SENSOR (OBD)

DTC P1336 CKP SENSOR (OBD)

PFP:23731

Component Description

UBS00DAQ

The crankshaft position sensor (OBD) is located on the transmission
housing facing the gear teeth (cogs) of the flywheel or drive plate. It
detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet, core and coil.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
This sensor is not used to control the engine system.
It is used only for the on board diagnosis.

DTC Confirmation Procedure

UBS00DAS

NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and wait at
least 5 seconds before conducting the next test.

 WITH CONSULT-II

1.

Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.

2.

Start engine and run it for at least 2 minutes at idle speed.

3.

If 1st trip DTC is detected, go to 

EC-448, "Diagnostic Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT-II”.
