04-06 Height Sensor TSB

[agaisin]

Anyone ever see this TSB "SU002-04" applicable to 04-06:
"To give customers a more consistent ride height and ride comfort, the front and rear height sensors have been improved."

It's very specific about how to tell which units are effected but it's not clear on the symptoms you'd experience, the cause of the problem, or the improvements made to the newer units.

Wonder if anyone else has more info on this?

Interesting find! You are the Sherlock Holmes of Toyota tech data.

On a more practical note: I ended up replacing all of the height sensors on my truck last year. The rear because it failed and, shortly thereafter, the fronts on the theory that they would probably have about the same life. So, i still have an original rear sensor; i should open up the new and compare.
