DTC P0335 - CKP SENSOR CIRCUIT MALFUNCTION Mitsubishi Eclipse II

Note. For component terminal identification, see TERMINAL IDENTIFICATION in this article. For wiring diagrams, see WIRING DIAGRAMS - 2.0L TURBO article.

1. Connect Test Harness (MD998478 ) between CKP sensor and harness connector. Check voltage between ground and test harness terminal No. 2 (Black clip). Voltage should be 0.4-4.0 volts, while cranking engine and 1.5-2.5 volts with engine idling. If voltage is not as specified, go to next step. If voltage is as specified, replace PCM.
2. Disconnect CKP sensor connector. Turn ignition on. Check voltage between ground and CKP sensor connector terminal No. 3 (Red wire). If battery voltage exists, go to next step. If battery voltage does not exist, check wiring harness between MFI relay connector and CKP sensor.
3. Check voltage between ground and CKP sensor connector terminal No. 2 (Blue/White wire). If battery voltage exists, go to next step. If battery voltage does not exist, check PCM connector and wiring harness between CKP sensor connector and PCM. If connector and wiring are okay, replace PCM.
4. Check continuity between ground and CKP sensor connector terminal No. 1 (Black wire). If continuity exists, check CKP sensor connector. If connector is okay, replace CKP sensor. If continuity does not exist, check wiring harness between ground and CKP sensor.
