Height Control Sensor: Inspection

WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT FRONT HEIGHT CONTROL SENSOR SUB-ASSEMBLY LH

Connect 3 dry cell batteries (1.5 V) in series.
Connect a positive (+) lead from the batteries to terminal 3 and the negative (-) lead from the batteries to terminal 1

Measure the voltage between terminals 2 and 1 while slowly moving the link up and down.

Standard Voltage
