Is the new sensor a GM part? I replaced mine once with a different brand from an auto parts store and it wouldn't work on my car. I don't know if it was just a bad sensor but the problem went away when I put in a sensor from the dealer. I've heard these cars are particular about their sensors but I don't know if its true.

You need to call Solo and ask them what the fix is. Someone here had the same issue a long time ago and it had to do with the position of the sensor been to far away and a software fix was the solution if my memory serves me right.

I would think they would tell me they cant help since their extender didnt work and I had to use a 90 degree extender from Amazon.

I wonder how the previous person fixed the problem.

I would suspect that your extender is isolating your O2 sensor too much. There's a happy medium in there. Did you try it without the extender?

Here's what I used. It had inserts which allow you to fine tune the signal response.

Also I tried it with the small extender that solo gives but immediately got the p0240 code. Put in the 90 degree extender and haven't Gor the p0240. UT just got the p2271 now.

Sounds about right. I got the P0240 code with no extender and have been good with the one above and no inserts. You need something a little less aggressive than the 90 degree. If you cut the sensor off too much from the exhaust then the computer doesn't see any response from the O2 sensor and throws a code.

That's what's wierd too...I did check the computer in real-time and it is getting a signal from that sensor. I would think I would get the delayed code instead of the p2271 which is saying that the car is running really rich....

With the extender you got....Did you use the fitting with the smaller opening, or did you use it with the big opening? Reason I ask....If it doesn't have an extension on it....That extender looks exactly like the one that Solo provides with their kit and threw the p0240 code on me....

The only other thing I can think of is that when the extender was added the shop had to put a new sensor on and maybe the wires are grounding occassionally somewhere.....

I wanted to update this....Called solo and they said they had never gotten a code p2271 with an angled extender.

Basically I followed the same process they would...They said if their straight extender didn't work they would put the angled extender in as well.

One thing they recommended that I didn't do was to clear the code three times. They said in a lot of cases when the ecu senses something even slightly off it will throw a code so they've learned to clear the codes a bunch of times and in a lot of cases the ecu will learn that the conditions are actually fine and the code will go away then..

I cleared the code once so I'll keep driving it and clear it a few more times to see if it goes away.
