ALL,

I recently had to replace the height sensors on my GX-470.

The dealer had no idea on how to adjust the height.

I did some manual adjustments on the sensor it self and observed that one can change the height position for NORMAL setting to ensure the vehicle is at correct height.


However I had many questions in my mind.

-What is the HEIGHT Specification at NORMAL POSTION .

-Is the response from the LEFT sensor different from the RIGHT Sensor.

-What is the starting point.

-Since FUEL TANK is on drivers side, how do we compensate for weight and height difference from LEFT to RIGHT side.


Would welcome feedback on how to adjust the sensors.

What is the correct procedure ?

Thanks

Could I know what prompted you to change the sensors, Before you change the sensors , Could you look at the EXhaust HEight Control Solenoid VAlve, Sometimes due to moisture intrusion, these sensor go bad, effecting the height Control Sensors. All you need to replaced the solenoid valve. These were a problematic ones on the 2003/2004 model GX. It is also called as Compressor Height Control Assy and the Part # 48910-60020. This once replaced will only be reset thru a Diagnostic Kit which is available at the dealer. As lot of interface is done to the ECM to understand the part number installed and clear the previous codes installed. I am bit surprised if the dealer say he does not know, try to change you dealer from your area to another one. Only one important thing the dealer should remember that there is Code DTC C1735 is not removed and it should be retained in the Suspension Control ECU.
