Today I changed the fluid in the ATTS system of my 1997 Prelude SH. 87,000 miles. I also changed out the Left Wheel Oil Pressure Sensor, since it was throwing code 62.

1.5 quarts(ish) of new ATF and an oil sending unit later I now have code 75 for Yaw Rate Sensor randomly coming on within 10 minutes of driving. It goes away each time I shut the vehicle off and comes back within 10 minutes each time.

What could I possibly be dealing with at this point? I had my hand up in the wiring harness removing the oil sensor, is the yaw sensor located near it? Could I accidentally have bumped the connector? Could the oil level be too full?

Anyone with ATTS knowledge please help.
Thank you!

Thank you!

I used 15-54 and found that, for my 1997, I had:

5.05v on 3-pin Yaw Rate Sensor terminal #1
(Specification states 8v minimum with key on)

2.15v on 3-pin Yaw Rate Sensor terminal #2
(Specification with key in the on-position is 2.5v minimum)

What this tells me is that the ATTS computer is not supplying the Yaw Rate Sensor with proper voltage. Am I correct?

Also, if I do need to replace the ATTS computer, will one out of a 1998 work as a replacement?

Thank you,
David

No one has any experience with this?
