How to fix these errors?

 

^
Since the codes are numerous & varied, it may be prudent to just visit the dealer or an experienced Acura / Honda specialty shop, no?

 

I have shown my car to multiple dealers and acura services center but no one is able to properly diagnose it and is able to fix it they say i would have to replace the turbo but then why there are stearing angle errors

 

How old is your battery?

How many of these codes come back when you clear them?

 

I recently changed my car battery around 6moths back. All codes come back after clearing.

 

Try a steering angle sensor re-learn with your scan tool, clear the codes, and see which ones come back.

 

I tried the steering angle sensor re-lean the error came back after couple of minutes.

 

Did all the codes come back after? Or did some of them not clear?

Also, can you provide some vehicle history? Did all these codes happen at once? How does the car drive otherwise?

What I'm thinking is that you have four underlying problems causing all these codes:

1. TPMS issues with the right front & rear tires - frustrating but not necessarily a drivability issue.

2. The dreaded P2263, likely caused by a worn eyebolt on the turbo actuator. Shops will tell you that you need a new turbo (technically that's what the service manual says), but there's a well-documented fix shared by other members on this forum - just search for the code with the 1G RDX subforum selected.

3. A whole bunch of ABS codes that may or may not all stem from the same failure. I can imagine e.g. a bad ABS pump causing all those codes, since it's also the "brains" for both traction control (VSA & SHAWD) systems.

4. The U0155 code pointing to an issue with the cluster gauge. Does it seem to be working properly?

P2263 and the ABS codes are more urgent to resolve IMO.

 

There are many things going on in with my car the car drives good but just those errors are bothering me.

so basically i am not a mechanic i don't know much of the stuff it would be helpful if you suggest a good mechanic near boston.

But I guess the errors are due to the steering angle sensor after resetting it again the errors came back.

 

Just sent you a PM.

I'd guess it's a bad ABS pump rather than any of those sensors it's complaining about. I'm not far from Boston and have a spare on hand; it's a very easy part to swap and see if that changes anything.

My roommate also knows how to weld so we might be able to fix the worn eyebolt causing P2263. No promises but happy to take a look.

 

Hi, please see your PM.

That would be great if you and your roommate could have a look what's going on with my car.

 

Updates: I ended up working on Adwait's RDX since we don't live too far from each other.

The turbo actuator had been replaced by another mechanic. Not the entire turbo, but not just the eyebolt either. It seemed to have fixed the P2263 issue at first (more on this below).

The car came to me with most of the same codes listed above - including P2263*. I replaced the ABS pump, did an ABS bleed on all four solenoids with my scan tool, and then cleared codes. After a test drive, the only codes remaining were for the gauge cluster and TPMS. No more P2263 or ABS codes. Bingo, or so I thought...

I got a text this morning from Adwait saying he's getting lights on the dash and codes again. The codes are mostly the same as before:

P2263
U0155
ABS codes 25 (yaw sensor), 26 (lat acceleration sensor), 47, and 85

*I had brushed this off as the prior mechanic not cleaning the code after doing the fix. In hindsight this wasn't very logical and should have alerted me to potential electrical gremlins, which is now what I'm thinking.

This RDX needs a brake bleed which we'll be doing next. I'm not sure if dirty brake fluid might be part of the culprit, at least with the ABS issues? I'd like to think it is, but of course that wouldn't explain P2263 coming back.

If anyone has any suggestions I'm all ears.

 

If you haven't already done so, double check the connecting bolt adjustment on the turbo actuator. If it's not positioned right, you can continue to trigger that P2263 even with the new eye bolt. Also, with the whole actuator being replaced, there's always the possibility that it's defective. If the original is still available, you can try swapping that back in and just focusing on the bolt itself. Most of the time it's just the worn bolt that throws the code.

 

Thanks for the tip. I hadn't looked at the eyebolt that closely and assumed it was fine.

This RDX has a new issue - P2647 pointing to the VTEC spool valve oil switch - so I'll need to remove the intercooler next time I work on this car. Good opportunity to inspect the eyebolt.
