Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (IG2 NO. 1 RELAY - PORT FUEL INJECTOR ASSEMBLY)
Result:
OK
See step 3
- CHECK HARNESS AND CONNECTOR (PORT FUEL INJECTOR ASSEMBLY - ECM)
- Disconnect the port fuel injector assembly connector.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
