Linkage, PowerTurbine/Input Shaft Speed Sensor, Output Shaft Speed Sensor [Fw6 A EL, Fw6 Ax
EL]
Purpose/Function
The turbine/input shaft speed sensor detects the rotation speed of the input
shaft (low clutch drum).
The output shaft speed sensor detects the rotation speed of the output shaft
(primary gear).
The turbine/input shaft speed sensor and output shaft speed ...
Transfer Removal/Installation [Fw6 Ax EL]
CAUTION:
Performing the following procedures without first removing the front ABS
wheel-speed sensor may possibly cause an open circuit in the harness if it is
pulled by mistake. Before performing the following procedures, disconnect the
front ABS wheel-speed sensor (axle side) and ...
Ion Sensor
Purpose/Function
Detects ion generation in the combustion chamber for detecting pre-ignition.
Detects ions which occur due to fuel combustion as current by applying bias
voltage to the spark plug, which is amplified in the ignition coil internal
circuit and input to the PCM.
