Lexus body position sensor
Content
Body position sensors are found on all second-generation RX vehicles.
On machines with air suspension, 4 sensors, one sensor for each wheel. On machines without pneuma, there is only one sensor, behind the right rear wheel.
From road chemicals, dirt, natural wear and age, sensors fail for a number of reasons:
- contact track wear
- electrical corrosion,
- loop cracking,
- fracture stretching.
The main problem when repairing the sensor is that, according to the idea of marketers, it is sold both in a set: a bracket, a rod and the sensor itself, or for a small piece of metal and plastic, it costs inadequate money, such as a well-known brand kitchen TV.
Rear sensors for four-wheel drive and front-wheel drive vehicles are characterized by long traction.
Front sensor codes:
- 89406-48020 - left,
- 89405-48020 - reg.
Rear sensor codes for XNUMXWD vehicle:
- 89408-48020 - left,
- 89407-48030, Aisin AST025 - right (pneuma + light).
Rear sensor codes for front wheel drive vehicle:
- 89408-48010 - left,
- 89407-48020 — right (pneuma + light).
For example, the right rear sensor of an all-wheel drive car, from different sides:
Rear sensors are located in very dirty places, behind the wheels, and most often fail.
That is why in this post attention is paid to the rear sensors.
1. Disassembling and cleaning the sensors can help.
It didn't help in my case. I disassembled and cleaned the problem sensor several times, eventually replaced it with a new one.
2. Sensors manufactured by Aisin (conveyor supplier) have appeared on sale.
AST025 - rear right for all-wheel drive vehicles.
I don't know any other codes. They say original.
Example of installation AST025 (Galeev M).
3. The original sensor is suitable for Land Cruiser 100/Lexus LX470 and Land Cruiser Prado 120/Lexus GX470; a new one is cheaper, a used one is more common at disassembly.
But it has a different mount and lever, that is, we take from it only the sensor itself and traction:
89407-60022, Aisin AST027 - rear right,
89408-60011, Aisin AST029 — Rear left.
Installation example for AST027 and AST029 (slkmaks91),
installation example AST029 (Igor-1709).
4. Sensor of the American company Dorman, code 924-755.
Judging by the cross-codes on the manufacturer's website, it is suitable for all-wheel drive (?!).
Sensor adjustment rod
1. The original drive can be purchased separately - from the rear sensor for Toyota Land Cruiser Prado 120 (Lexus GX470, Toyota 4Runner):
48906-35010 - rear right (bought for me),
48906-35020 — rear left.
In online stores, many Chinese analogues of original rods are produced.
But they cost similar money (if you buy the original at Burj Auto), and the quality from China is unknown.
LC100 (LX470) rods (there are a lot of numbers) are also suitable, but they are more expensive than Prado rods.
My bar broke, apparently due to a soured hinge (it was developed and lubricated a year ago). Next to the Prado lunge, it is identical:
3. If the rod breaks and has points, then you can make a rod with a bolt of the appropriate length by cutting off the cap
After replacing the sensor or probe, the position of the vehicle may change.
The adjusting nut on the stem changes the height level.
