C1712 Code: Meaning, Causes, and Symptoms | OBD2 Codes
C1712 – Front Height Control Sensor Left Circuit Malfunction
C1712 Possible Symptoms
Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)
C1712 Possible Causes
Faulty Front Height Control Sensor Left,Front Height Control Sensor Left harness is open or shorted,Front Height Control Sensor Left circuit poor electrical connection
Inside each sensor, a brush integrated with the control sensor rotor shaft moves above the resister, providing linear output. The resistance value between the brush and resistor terminal changes in proportion to the shaft rotation angle, so the fixed voltage applied to the resistor by the ECU is modified by the sensor and output to the ECU as a voltage indication the shaft rotation angle.
