Caution
• The PCM terminal voltages vary with change in measuring conditions and vehicle conditions.
Always carry out a total inspection of the input systems, output systems, and PCM to determine
the cause of trouble. Otherwise, a wrong diagnosis will be made.

1. Measure the voltage at each terminal.

• If any incorrect voltage is detected, inspect the related system(s), wiring harnesses and connector(s)
referring to the Action column in the terminal voltage table.

1. Perform the following procedure to making the working space.
(1) Remove the Front wheel (RH).
(2) Remove the splash shield.
2. Disconnect the CKP sensor connector.

•
3. Remove the installation bolts to remove the CKP sensor.

Installation

Caution
• When foreign material such as an iron chip is on the CKP sensor, it can cause abnormal output
from the sensor because of flux turbulence and adversely affect the engine control. Be sure there
is no foreign material on the CKP sensor when replacing.

1. Perform the following procedure so that piston No.1 is at the top dead center.
(1) Remove the front drive shaft (RH). (See 03-13-16 FRONT DRIVE SHAFT REMOVAUINSTALLATION [L3,

(2) Remove the cylinder block lower blind plug
and install the SST.
(3) Turn the crankshaft pulley to the clockwise

Air Gap Inspection

1. Verify that the CKP sensor is securely installed.
2. Using a thickness gauge, measure the air gap between the plate projections at the back of crankshaft pulley
and the CKP sensor.
• If not within the specification, inspect the plate projections for cracks or bending.
If there is any malfunction, replace the plate.
- If the monitor item condition/specification (reference) is not within the specification, even though there is
no malfunction, carry out the "Circuit Open/Short Inspection".

PCM INSPECTION [L3 WITH TC]

E6U014018880W12
Using the WDS or Equivalent

Note
• PIDs for the following parts are not available on this model. Perform the specific inspections for the
following parts:
CMP sensor (See 01-408-36 CAMSHAFT POSITION (CMP) SENSOR INSPECTION [L3 WITH
TC].)
- Main relay (See 09-21-7 RELAY INSPECTION.)
1. Connect the WDS or equivalent to the DLC-2.
2. Turn the ignition switch to the ON position.
3. Measure the PID value.
• If PID value is not within the specification,
follow the instructions in the "Inspection item"
column.
Note DLC-2
• The PID/DATA MONITOR function monitors
the calculated value of the input/output
signals in the PCM. Therefore, an output
device malfunction is not directly indicated
as a malfunction of the monitored value for A6E3970W002
the output device. If a monitored value of an
output device is out of specification, inspect the monitored value of the input device related to the output
control.
• For input/output signals except those of the monitoring items, use a voltmeter to measure the PCM
terminal voltage.
• The simulation items that are used in the ENGINE CONTROL SYSTEM OPERATION INSPECTION are
as follows.
- ACCS, ALTF, ARPMDES, FAN_DUTY, EVAPCP, FP, FUELPW1, GENVDSD, HTR11, HTR12, IMRC,

Caution
• The PCM terminal voltages vary with change in measuring conditions and vehicle conditions.
Always carry out a total inspection of the input systems, output systems, and PCM to determine
the cause of trouble. Otherwise, a wrong diagnosis will be made.

1. Measure the voltage at each terminal.

• If any incorrect voltage is detected, inspect the related system(s), wiring harnesses and connector(s)
referring to the Action column in the terminal voltage table.

1. Connect the WDS or equivalent to the DLC-2.
2. Perform the vehicle identification procedure.
3. Select "toolbox" and "Module Programming".
4. Select "Programmable Module Installation".
5. Select "PCM" and perform procedures according
to directions.

Note
• If the PCM is replaced with a new one
without performing "Programmable Module
Installation" procedure, the PCM will be set
DTC P0602 and illuminates the MIL. This is
A6E3970W002
because the configuration data is not
programmed in the PCM.

6. Retrieve DTCs with the WDS or equivalent, erase them, and verify that there are no DTCs present and the MIL
is off.
• If DTCs are still present, perform applicable DTC inspection.

Removal
1. Perform the following procedure to allow for enough working space.
(1) Remove the Front wheel (RH).
(2) Remove the splash shield.
2. Disconnect the CKP sensor connector.

•
3. Remove the installation bolts to remove the CKP sensor.

Installation

Caution
• When foreign material, such as an iron chips, gets on the CKP sensor, it can cause abnormal
output from the sensor because of flux turbulence and adversely affect engine control. Be sure
there is no foreign material on the CKP sensor when replacing.

1. Perform the following procedure so that piston No.1 is at the top dead center.
(1) Remove the drive shaft (RH). (See 03-13-16 FRONT DRIVE SHAFT REMOVAL/INSTALLATION [L3, L3
WITH TC].)
(2) Remove the cylinder block lower blind plug
and install the SST.
(3) Turn the crankshaft pulley to the clockwise
until it stops.

Using a straight edge, draw a straight line directly EMPTY SPACE

in the center of the twentieth tooth of the
crankshaft pulley pulse wheel (counting
counterclockwise from the empty space). MARK LINE AT CENTER
OF 20TH TOOTH

Caution
• If the line is not accurately drawn,
ignition timing, fuel injection and other
engine control systems will be adversely
effected. Draw the straight line carefully
using a straight edge.

3. Align the center line of the crankshaft position

sensor and the line drawn in Step 2, then install
the sensor.
4. Install the CKP sensor fitting bolts.

Note
• Before performing the following inspection, make sure to follow the troubleshooting flowchart.

Front H02S Current Inspection

1. Warm up the engine to normal operating temperature.
2. Using the WDS or equivalent, monitor the following:
- Vehicle speed (PID: VSS)
- Engine speed (PID: RPM)
- Front H02S current {PID: 02S11)
3. Drive the vehicle and decelerate the engine speed by releasing the accelerator pedal fully when the engine
speed is 3,000 rpm or more.
4. Verify that the front H02S current {PID: 02S11) is 0.25 mA or more while decelerating as shown in the figure.

Note
• Before performing the following inspection, make sure to follow the troubleshooting flowchart. (See 01-
03C-5 FOREWORD [AJ].)

H02S voltage inspection

1. Warm up the engine to normal operating temperature.
2. Using the WDS or equivalent, monitor the following:
- Vehicle speed (PID: VSS)
- Engine speed (PID: RPM)
- H02S voltage (PID: 02S11/02S12/02S21/02S22)
3. Drive the vehicle and decelerate the engine speed by releasing the accelerator pedal fully when the engine
speed is 3,000 rpm or more.

 CONTROL SYSTEM [AJ]
4. Verify that the H02S outputs a voltage of 0.6 V or more, one time or more, then verify that the H02S voltage
(PID: 02S11/02S12/02S21/02S22) is 0.3 V or less while decelerating as shown in the figure.

Note
• Perform the following inspection only when directed.
• The following vacuum values are indicated by relative pressure from the EGR boost sensor.
Voltage Inspection

•
1. Connect the WDS or equivalent to the DLC-2.
2. Turn the ignition switch to the ON position.
3. Select BARO PID on the WDS or equivalent.
4. Verify that the BARO PID (pressure) and
barometric pressure are practically equal.
• If verified, go to next step.
• If not verified, perform the "Circuit Open/Short
Inspection".
Caution
• Do not apply vacuum out of specification.
Doing so will damage the EGR boost
sensor. B6U01 02W501
5. Apply vacuum of -25.0 kPa {-187 mmHg, -7.38
inHg} to the EGR boost sensor, and verify that the BARO PID variation from that of Step 4 is approx. 25.0 kPa
{187 mmHg, 7.38 inHg}.
• If verified, replace the EGR boost sensor.
