vss speed sensor is a sensor to detect the engine rpms to sabaer speed in different gears either slow or fast
may be two
GENERATOR MAGNET PERMANENT
this voltage generates low voltage
OPTICAL LENS
which has a light emitting diode and a
fototranmisor generally these sensors are checked with the multimeter on the ohms function of 3-8 ohm resistive value their input voltages as well as the output for the ECU are approximate to 5 -8 volts
when this sensor is an evil state has failed or the symptoms that arise can be
