FI SYSTEM DIAGNOSIS 12-29
“12” (P0335) CKP SENSOR CIRCUIT MALFUNCTION
NOTE:
After repairing the trouble, clear the DTC using SDS tool. (12-21)
INSPECTION
Step 1
1) Stop the engine.
2) Check the CKP sensor coupler 1 for loose or poor contacts.
If OK, then measure the CKP sensor resistance.
3) Disconnect the CKP sensor coupler and measure the resis-
tance.
CKP sensor resistance: 80 – 120 Ω
(Green – Red)
DETECTED CONDITION POSSIBLE CAUSE
The signal does not reach ECM for 1 second or
more, after receiving the IAP sensor input 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.

BI
When using the multi circuit tester, do not strongly touch the terminal of the ECM coupler with
a needle-pointed tester probe to prevent the terminal damage or terminal bend.
