FI SYSTEM DIAGNOSIS 4-35 “C12” (P0335) CKP SENSOR CIRCUIT MALFUNCTION DETECTED CONDITION POSSIBLE CAUSE The signal does not reach ECM for 3 sec. or more, • Metal particles or foreign material being stuck on after receiving the starter signal. the CKP sensor and rotor tip • CKP sensor circuit open or short • CKP sensor malfunction • ECM malfunction ECM CKP sensor B G/W CKP G G/BI CKP INSPECTION 1 E Step 1 L 1) Turn the ignition switch OFF. P 2) Lift and support the fuel tank. (5-3) 3) Check the CKP sensor coupler for loose or poor contacts. M If OK, then measure the CKP sensor resistance. SA 4) Disconnect the CKP sensor coupler and measure the resis- 1 tance. CKP sensor resistance: 142 – 194 Ω (Black – Green)
