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” .

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.  Remove the air cleaner box. Refer to “air cleaner box removal and installation” in section 1d .
  4.  Check the cmp sensor coupler (1) for loose or poor contacts.

    If ok, remove the cmp sensor. Refer to “cmp sensor removal and installation” in section 1c .


  1. Connect 3 new 1.5 V batteries in series, 1 kΩ resistor and the multi-circuit tester as shown in the figure.

Special tool : 09900–25008 (multi circuit
tester set)

Tester knob indication voltage ( )



  1. Under this condition, if a suitable screwdriver touching the pick-up surface of the cmp sensor is moved, the tester reading voltage changes (0.8 V and less . 4.3 V and more).


Is the voltage ok?

  • B/y, r or b/br wire open or shorted to ground.
  •  Loose or poor contacts on the cmp sensor coupler or ecm coupler (terminal “7”, “8” or “35”).
  •  If wires 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.
  • B/y, r or b/br wire open or shorted to ground.
  •  Loose or poor contacts on the cmp sensor coupler or ecm coupler (terminal “7”, “8” or “35”).
  •  If wires 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.
  • Inspect that metal particles or foreign material stuck on the cmp sensor and camshaft tip.
  •  If there are no metal particles and foreign material, then replace the cmp sensor with a new one.
  • Inspect that metal particles or foreign material stuck on the cmp sensor and camshaft tip.
  •  If there are no metal particles and foreign material, then replace the cmp sensor with a new one.
