What does a Tdc sensor signal look like?

a TDC sensor has a 12v feed from either the ecu or an ignition relay. a ground and a signal output to the ecu. this signal can be called a digital signal ie its on or its off. off state being 0v on usually being 5v althiugh this voltage can be different depending on make of sensor and vehicle. The voltage output would show on a scope as a square wave. a TDC sensor has a 12v feed from either the ecu or an ignition relay. a ground and a signal output to the ecu. this signal can be called a digital signal ie its on or its off. off state being 0v on usually being 5v althiugh this voltage can be different depending on make of sensor and vehicle.
