Removal [LH] 1. Remove the Intake manifold. (Refer to Intake And Exhaust System - "Intake Manifold") 2. Remove the high pressure fuel pump.
Description Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load.
Removal Height Sensor 1. Remove the height sensor connector (A). 2. Loosen the mounting bolts(Body: 2EA, chassis: 1EA) from height sensor bracket. Tightening torque : 3 ~ 5N.m (30 ~ 50kgf.m, 2.21 ~ 3.68lb-ft) 3. Remove the height sensor.
Diagnosis With GDS 1. BSD system defects can be quickly diagnosed with the GDS. GDS operates actuator quickly to monitor, input/output value and self diagnosis. 2. Connect the cable of GDS to the data link connector in driver side crash pad lower panel, turn the power on GDS.
