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
