So, if you want to test the ABS sensor first, never forget bring voltmeter with you. It will detect a bad speed sensor, it has no idea what the cluster is doing. The first is known as the input shaft speed (ISS) sensor. Check Nearby Stores. The second type of speed sensor that may be used on Toyota vehicles is the wheel speed sensor. Desired = Actual = Gauge: The governor pressure control system is working properly. * The 45RFE / 545RFE transmissions use two sensors, an input speed sensor and an output speed sensor. Ships for free on orders over $25. AT-4 AUTOMATIC TRANSMISSION - Description ECT Aside from having an ECU which controls shifting based upon electrical speed and throttle opening signals, the ECT is basically the same as a fully hydraulic controlled automatic transmission. • When transmission defects were not too common before 2005, the Mereceds Benz 6 speed gearboxes used to go into a true "limp home mode" where the driver could never shift the gear beyond first gear till the failed internal sensor or mechanical defect was addressed in a workshop. fourth gear, transmission output speed is more than engine input speed. There are two leads to this speed sensor, and the two leads do not go to the same place on the buffer. VW transmission speed sensor. Getting Back Up to Speed A good transmission speed sensor is essential to getting peak performance from your ride. The transmission is electronically controlled by the Transmission Control Module (TCM) to operate the transmission gear selector. € € € Special tools and equipment€ The 2005 Chevy Cavalier vehicle speed sensor is located on the back of the transmission. 0 liter Pacifica. lbs. The needle should deflect indicating the switch is opening/closing as the rotor moves past the sensor (Fig. Loss of a wheel speed signal is a serious problem because the ABS module needs accurate input from all its sensors to determine whether or not a wheel is locking up. Commonly these units can throw gear ratio codes , or exhibit erratic shift problems related to the signal coming from these sensors. The '97 PCM tested the same voltage as the '96. If the speed signal fails when the engine is running, it will cause the engine to stall immediately. The car senses an issue with the primary speed sensors then falls back on the secondary speed sensor in the transmission. The VSS is used extensively for transmission shifting in TCM applications as well as  Sensors for non intrusive acquisition of turbo charger's speed. Symptom: Vehicle is extremely slow. Sometimes, fine metal shavings or or a paste like film from normal transmission wear can cover the end of the sensor.
