Troubleshooting

Caution

when using the multi-circuit tester, do not strongly touch the terminal of the ecm coupler with a needle pointed tester probe to prevent terminal damage.

 

Note

after repairing the trouble, clear the dtc using sds tool. Refer to use of sds diagnosis reset procedures .

 

Step

Action

Yes

No

1

  1. Turn the ignition switch off.
  2.  Lift and support the fuel tank. Refer to fuel tank removal and installation in section 1g .
  3.  Check the primary fuel injector coupler (1) for loose or poor contacts.

    If ok, then measure the injector resistance.


  1. Disconnect the injector coupler and measure the resistance between terminals.

Special tool
(a): 0990025008 (multi
circuit tester set)

Tester knob indication resistance (Ω)

Injector resistance 11 13 Ω at 20 c (68 f) (terminal terminal)


  1. If ok, then check the continuity between each terminal and ground.

Special tool
(a): 0990025008 (multi
circuit tester set)

Injector continuity ∞Ω (infinity)


Are the resistance and continuity ok?

Go to step 2. Replace the injector with a new one. Refer to throttle body disassembly and assembly in section 1d .

2

  1. Turn the ignition switch on.
  2.  Measure the injector voltage between the y/r wire and ground.
Note

injector voltage can be detected only for 3 seconds after ignition switch is turned on.

Special tool
(a): 0990025008 (multi
circuit tester set)

Tester knob indication voltage ( )


Injector voltage battery voltage ((+) terminal: y/r () terminal: ground)


Is the voltage ok?

  • Gr/w wire open or shorted to ground, or poor 46 connection (#1 cylinder side).
  •  Gr/b wire open or shorted to ground, or poor 45 connection (#2 cylinder side).
  •  Gr/y wire open or shorted to ground, or poor 44 connection (#3 cylinder side).
  •  Gr/r wire open or shorted to ground, or poor 43 connection (#4 cylinder side).
  •  If wire and connection are ok, intermittent trouble or faulty ecm.
  •  Recheck each terminal and wire harness for open circuit and poor connection.
  •  Replace the ecm with a known good one, and inspect it again. Refer to ecm removal and installation in section 1c .
Open circuit in the y/r wire.
