Inspection Procedure
NOTE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
- INSPECT FUEL INJECTOR (POWER SOURCE)
- Disconnect the fuel injector connectors.
- Turn the ignition switch to ON.
- Measure the voltage according to the value (s) in the table below.
Standard Voltage
TESTER CONNECTION SPECIFIED CONDITION CHARTTester Connection Switch Condition Specified Condition B57-1 - Body ground Ignition switch ON 11 to 14 V B56-1 - Body ground Ignition switch ON 11 to 14 V B55-1 - Body ground Ignition switch ON 11 to 14 V B54-1 - Body ground Ignition switch ON 11 to 14 V - Reconnect the fuel injector connectors.
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (IG2 RELAY - FUEL INJECTOR)
OK: Go to next step
- INSPECT FUEL INJECTOR (INJECTOR RESISTANCE)
- Inspect the fuel injector (See INSPECTION
).
NG: REPLACE FUEL INJECTOR (See REMOVAL )
OK: Go to next step
- Inspect the fuel injector (See INSPECTION
).
- CHECK HARNESS AND CONNECTOR (FUEL INJECTOR - ECM)
- Disconnect the ECM connector.
- Disconnect the fuel injector connectors.
- Measure the resistance according to the value (s) in the table below.

- CHECK HARNESS AND CONNECTOR (ECM - BODY GROUND)
- Disconnect the ECM connectors.
- Measure the resistance according to the value (s) in the table below.
Standard Resistance (Check for Open)
TESTER CONNECTION SPECIFIED CONDITION CHARTTester Connection Condition Specified Condition B48-1 (E01) - Body ground Always Below 1 Ω B49-12 (E02) - Body ground Always Below 1 Ω - Reconnect the ECM connectors.
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- INSPECT FUEL INJECTOR (INJECTION AND VOLUME)
- Check the fuel injector injection and volume (See INSPECTION
).
NG: REPLACE FUEL INJECTOR (See REMOVAL )
OK: PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE (See PROBLEM SYMPTOMS TABLE )
- Check the fuel injector injection and volume (See INSPECTION
).
