Suzuki GSX-R 1000 Service Manual: DTC “c12” (p0335): ckp sensor circuit malfunction.

Detected condition and possible cause

Detected condition

Possible cause

The signal does not reach ecm for 3 sec. Or more, after receiving the starter signal.
  • Metal particles or foreign material being stuck on the ckp sensor and rotor tip.
  •  Ckp sensor circuit open or short.
  •  Ckp sensor malfunction.
  •  Ecm malfunction

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 ckp sensor coupler (1) for loose or poor contacts.

    If ok, then measure the ckp sensor resistance.


  1. Disconnect the ckp sensor coupler and measure the ckp sensor resistance.

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

Tester knob indication resistance (Ω)

Ckp sensor resistance 142 – 194 Ω (b – bl/y)


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

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

Ckp sensor continuity ∞Ω¶ (infinity) (b . Ground, bl/y. Ground)


Are the resistance and continuity ok?

Go to step 2. Replace the ckp sensor with a new one.

2

  1. Crank the engine several seconds with the starter motor, and measure the ckp sensor peak voltage at the coupler.

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

Tester knob indication voltage ( )


Ckp sensor peak voltage 0.5 V and more ((+) terminal: b – (–) terminal: bl/y)


  1. Repeat the 1) test procedures several times and measure the highest peak voltage.

Is the voltage ok?

  • B or bl/y wire of the harness side open or shorted to ground.
  •  Loose or poor contacts on the ckp sensor coupler or ecm coupler (terminal “9” or “21”).
  •  If the 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. Refer to “ecm removal and installation” in section 1c .
  • Inspect that metal particles or foreign material stuck on the ckp sensor and rotor tip.
  •  If there are no metal particles and foreign material, then replace the ckp sensor with a new one. Refer to “ckp sensor removal and installation” in section 1c .
