INTERMEDIATE SENSOR CONSTRUCTION/OPERATION[FS5A-EL]
id051721113300
• The intermediate sensor is a GMR element type. A 82-pulse signal is generated per rotation of the secondary gear and the intermediate sensor sends this signal to the TCM.
• Consists of an IC in which a giant magneto resistive (GMR) element and signal processing circuit have been integrated, and a magnet. Signal reliability has been improved with the adoption of the GMR element resulting in the signal amplitude being wider compared to the hall element.
• Signal detection uses the special characteristics of GMR to change the electrical resistance corresponding to the magnetic field.
• The size (GMR output) of the magnetic field detected by the GMR element is changed into rectangular waves as a sensor output signal at the signal processing circuit.
• The TCM detects the shift start/stop timings based on the signals from the intermediate sensor and performs a detailed control, improving the shift quality.
