Low Output Signal of Front Speed Sensor RH (Test Mode DTC) (C1271,C1272,C1401,C1402)
DESCRIPTION
The speed sensor detects the wheel speed and sends the appropriate signals to
the skid control ECU (master cylinder solenoid). These signals are used for brake
control.
The speed sensor rotors have rows of alternating N and S magnetic poles and their
magnetic fields change when t ...
