Having four different part numbers was probably a "by design" factor so that intelligent people like you and I (et al) would not think to swap them over
Consider also that MANY different auto companies - retailers, wholesalers and manufacturers - supply or are supplied a wide range of parts for an even wider range of cars and spare part companies. The part will be EXACTLY the same but will be packaged differently and of course have a totally different part number, some will be exorbitantly priced!
I just turned it "over" to fit on "the other side" of the car and then flipped the arm, by rotating the sensor shaft, to suit that orientation. This was no "mechanical" adjustment other than turning the shaft.
After being in various service industries for most of my working life, I never even considered that they would be different on each "corner" of the car.
I just naturally expected from a manufacturing point of view that the makers would not "tool up" for four different parts when ONE would do the job.
While that could very well be correct, I don't see why the manufacturers would change their ways - they may have been made by a different company?
This is a more likely scenario. After all if they can sell a NEW part at a VERY HIGH PRICE, as does our local dealer here in Western Australia, why would they "offer" to fix something for a minimal labour charge?
IIRC I did take off the height sensor I thought was faulty and checked it by flipping the arm 180° and checking with a multimeter.
Some time after doing my EAS overhaul I picked up a faulty sensor from one of the (GOOD) local service centres and pulled of the backplate.
I was impressed with its internal quality. If I find the photos I took I'll post them for forum members.
Good info and food for thought. Cheers.
