I might have a similar problem. I feel a slip in the steering wheel when I give it some abrupt input, especially in low speed. No EPS light though. How would you describe the problem ?

 

Hmmmm. I did not feel anything like a "slip", just a difference in the effort required when turning the steering wheel one way or the other. This was evident with the car either moving or not moving.

If the steering effort is even and normal, I would look carefully at the front suspension, tie rod ends, front tires, front wheel bearings, lug nuts, etc, etc. If the steering effort is very high (easily noticed while car is not moving), then you might have an unlikely situation where the steering assist is not working, and occasionally kicks in when you make a large steering effort. If that is happening, you should be able to duplicate it with the car not moving.

 

Thanks for the writeup Alf! I definitely tried to change out the torque sensor without adjusting the preload since it was pretty tough to get to. You definitely need to do it.

Here is the part number for the tool that Alf made: 07916-SA50001 or 07AAA-TL2A100

 

What was the trick to completing the sequence? I tried about a dozen times as well but after the second time at 45 degrees left I just get the codes blinking.

 

I hate digging this up from the grave, but my car is acting identically. 2001. Can't get through the reset procedure, steering all funky. Just curious, did you check the resistance at the torque sensor per the manual to determine it was bad or was there more involved checking? I hate to spend $300 on a hunch.

What kind of grease do you use on the TS pinion gear?

 

also, where is the steering rack preload bolt located?

- EDIT I found it, looks like it's right above where the TS goes in. Hard to see.

 

I just did this job, cleaning and replacing the original TS. I used a combination of Alf_09NFR's instructions and another excellent writeup at https://docs.google.com/document/d/1...TbSfJzPYE/edit

A few notes on my experience:

1. You CAN do this job without the special tool or loosening the steering rack preload bolt (although it's a little harder). If you have someone wiggle the wheels back and forth while you push in the torque sensor, it will go in. It took about 15 minutes of wiggling till the gears lined up in the magical position to engage, but it works.

2. The stamped letters do NOT need to be straight up. According to the service manual and diagram (quoted below), within 30 degrees is acceptable. Mine did not go in perfectly straight up and it works fine after the repair, I just had to shift the steering spline over one notch to get the wheel straight. I did not need to reprogram the center potion.

3. I agree that the original grease used inside the TS and on the pinion gear is Honda Hi-Temp Urea grease. I can't be 100% sure, but it has the exact same distinct greenish color as the Urea grease.

Torque Sensor Replacement

Note these items during replacement:
-

Do not allow dust, dirt, or other foreign materials to enter the gearbox.

-

Do not try to disassemble the torque sensor assembly. If the torque sensor is faulty, replace it as an assembly.

-

If the torque sensor is replaced, the EPS control unit must memorize the torque sensor neutral position.

1. Center the steering rack within its stroke.

2. Remove the torque sensor assembly (A).
3. Coat the new O-ring (B) with grease, and carefully fit it on the torque sensor housing.
4. Apply grease to the needle bearing (C) in the gearbox housing.
5. Install the torque sensor assembly (A) on the gearbox housing by engaging the gear.

The alphabet stamping (for example "AB") (D) on the pinion shaft aligns with the rack guide screw (E) when the rack is in the straight ahead
driving position.
When installing the torque sensor assembly, make sure the "alphabet" stamping ("AB") is within the range.

6. Tighten the 8 mm flange bolts (F).
