Morning, I completed some AHC maintenance on my 2006 LX470 over the weekend starting with a full fluid flush -- big thanks to this community for all the instructions/guides. The flush went successfully and immediately noticed some ride improvements.
Before the flush, everything with the system worked nicely except a c1723 code. I think the code is due to an exhaust leak I had frying some wires but will have that addressed later.
I wanted to level out some of the rake in the stance so attempted last night to adjust the front sensors slightly to get ~3/4" increase in height and then adjust the torsion bars to ensure pressures were in spec.
I think I've messed up at least one (maybe both) of my front height sensors but wanted a gut check. I am new to wrenching so although I'm kicking myself am gonna try and not beat myself up too much.
I jacked up the car and shortened each of the height sensor rods. And when I let the car back down off the jack and turned it on, the whole front end immediately dropped to the bump stops. Height showed as "N" and would not go into "H" or "L". Tech Stream, was getting a reading of FR +3.2 in and FL - 3.3 in (obviously not good). Prior to adjusting the rods, everything was reading normal (+/- a few tenths of an inch at "N" with about 19.25" b/w center hub and fender) and the car went up to H and down to L flawlessly.
So here's where I think I went wrong (kicking myself). When I adjusted the rods, I removed bolt circled in red in the screenshot below to more easily adjust the rods, and didn't realize that the sensor arm seats onto a rectangular piece. When I re-attached the arm, I did not seat the arm into the rectangular piece and simply tightened bolt. I'm assuming that once the car was lowered off the jacks caused mechanical damage to the sensor.
I realized my mistake and reseated the arms back onto the rectangle but the readings didn't change and car is stuck with the front end on the bumps.
Here are my options:
1) Throw in the towel, have it towed to my local show (Richmond Import Services)
2) Continue diagnosing to see if existing sensor can be salvaged
3) Purchase new sensor and install and see if that resolves -- with this option, the idea of spending $400+ per sensor from the dealer is nauseating. I see the Aisin sensors are ~$150-$200 each. I also see cheaper options that I would be cautious about.
