Using SST (WDS or Equivalent) Procedure

NOTE
- PIDs for the following parts are not available on this model. Go to the appropriate part inspection.
- ECT sensor (Water temperature sender unit). (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION.)
- Camshaft position sensor. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION.)
- Main relay. (See RELAY INSPECTION.)

1. Connect the WDS or equivalent to the DLC-2.
2. Turn the ignition switch to ON.
3. Measure the value.
- If value is not within the specification, follow the instructions in ACTION column.

FTP PID inspection procedure

1. Confirm the ignition switch is turned to ON.
2. Confirm that the following PIDs are within the specifications:

BARO
101.3 kPa {760 mmHg, 29.9 inHg} (Absolute pressure)

IAT
30 - 100 °C {86 - 212 °F}




3. Disconnect the FTP sensor connector and measure the voltage at FTP sensor connector terminal C.

Voltage: 5.0 V

4. Reconnect the connector.
5. Disconnect the vacuum hose from the FTP sensor.
6. Connect the vacuum pump to the fuel tank pressure sensor.
7. Select FTP PID on the WDS or equivalent.
8. Apply the vacuum and verify that the FTP is as specified on the table.

BARO PID inspection procedure

1. Confirm the ignition switch is turned to ON.
2. Confirm that the following PIDs are within the specifications:

BARO
101.3 kPa {760 mmHg, 29.9 inHg} (Absolute pressure)

IAT
10 - 50 °C {50 - 122 °F}




3. Disconnect the EGR boost sensor connector and measure the voltage at EGR boost sensor connector terminal C.

Voltage: 4.5 - 5.5 V

4. Reconnect the connector.
5. Disconnect the vacuum hose from the EGR boost sensor.
6. Connect the vacuum pump to the EGR boost sensor.
7. Select BARO PID on the WDS or equivalent.
8. Apply the vacuum and verify that the BARO PID is as specified on the table.

Vref terminal circuit inspection

1. Turn the ignition switch to ON.
2. Measure the voltage between the TP sensor connector (vehicle side) terminal A and body GND using a voltmeter.

1. Measurement voltage is 0 V.
1. Turn the ignition switch to LOCK.
2. Disconnect the TP sensor connector, EGR boost sensor connector, and FTP sensor connector (to which Vref is applied).




3. Verify there is no continuity between the TP sensor connector (vehicle side) terminal A and body GND using an ohmmeter.
- If there is continuity, repair the related harness for short to circuit.







4. Inspect for continuity between the PCM connector (vehicle side) terminal 4L and each sensor connector (vehicle side) terminals to which Vref is applied using an ohmmeter.
- If there is continuity, repair the related harnesses.

2. Measurement voltage is B+.
1. Turn the ignition switch to LOCK.
2. Disconnect the battery positive harness and battery negative harness.
3. Verify there is no continuity between the TP sensor connector (vehicle side) terminal A and battery positive harness using an ohmmeter.
- If there is continuity, repair the related harnesses for short to B+ circuit.




3. Measurement voltage is approx. 5 V.
- Vref terminal of PCM is okay.

GND circuit inspection

1. Turn the ignition switch to LOCK.
2. Disconnect the PCM connectors.




3. Inspect for continuity between the PCM GND terminals and body GND using an ohmmeter.
- If not as specified, repair the related harnesses for open circuit.

Power supply circuit inspection

1. Turn the ignition switch to LOCK.
2. Disconnect the PCM connectors.




3. Measure the voltage between the PCM battery power terminal and body GND using a voltmeter.
- If not as specified, repair the related harnesses and fuses.

Power supply terminal voltage: B+

Serial communication terminal inspection

1. Turn the ignition switch to LOCK.
2. Disconnect PCM connectors.




3. Verify there is continuity between PCM connector terminal 3Q and DLC-2 KLN terminal.
- If not as specified, repair the related harnesses.
