Thanks for clarifying that. Just tested it and it seems like my speed sensor is ok. Disconnected my reference sensor and the engine didn't die and kept idling.
One more thing I noticed If I may ask you guys, when the car is on the Idle valve controller is vibrating. not ignition, but when the car is running the and at idle, the idle valve controller is vibrating softly. is that normal?
