The resistance of the good working crankshaft sensor is 200Ω to 2000Ω. If the resistance is zero ohms, it indicates a short circuit. When determining the amount of resistance a crankshaft sensor should have, a variety of factors must be considered. The kind of engine, the age of the engine, and the operating conditions all play a role in how much resistance the sensor should have. In general, newer engines will have sensors with less resistance than older engines. Additionally, engines that are operated in harsher conditions (e.g., high temperatures or dusty environments) will also have sensors with less resistance.
