2004 Civic CKP Issues. All tests good!?!?
ECU was throwing P0336 -CKP Intermitent. Car would start easily into Limp Mode. Replaced CKP sensor, cleared ECU. Would not start. Kept cranking for about 6 seconds engine light comes in and starts into Limp Mode. ECU throws P-0336 again. Tested. Have 12v on pin1, ground on Pin2 and 1400ohms 0v on pin3 with key off. With key on same except get 5v on pin3. Tested CKP sensor by hand cranking engine- get 5v pulses every few degrees with a long pulse every rotation. Tested pin 7 on ECU connector - no shirt to ground on blue wire or open to connectorEverything checks out... what next? Should I replace ECU at this point?
