Re: Speed Sensors - Saabnet.com Bulletin Board
The difference in right and left front speed sensors is the length of the wires, and maybe the connectors IIRC. Nominal sensor resistance is 1000 Ohms. I would be more concerned about the 1100 Ohm reading. Sensors like to fail open and may do so intermittently. Another common problem is the sensing end of the sensor and exciter teeth getting cruded up. The slightest touch between the sensor and exciter teeth, or gap that is too large, can mess up the sensor signal. Speed sensors like sharp edges on the leading and trailing of the exciter teeth.
