I’m getting a code reading for P2135. It’s on a Chevy Silverado Z-71 with a 5.3L [engine](/topics-engine-chevy/). Ruff idle, high rpm, traction link shows off and stabilitrak shows off. Mechanic's Assistant: How many miles are on the Chevy? What size is the engine? 172203 miles and has a 5.3L Mechanic's Assistant: What is the model/year of your Chevy? It’s a 2012 Z-71 pickup Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far? I ain’t smart enough to fix it myself. I haven’t done anything to it. Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Just that I’m sitting on side the road outside Jackson Mississippi

Good morning Stacy. Nice to see you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Please give me one moment to type out some information for you. Sit tight one minute. I'll be right back!

OkCan I send you a picture of the code that it's showing on my OBD II
Automotive Expert
Thank you for holding Stacy, The code P2135 is a common code to set on your 2112 Z-71 with the 5.3 engine and in most cases its set due to a failing throttle body. Your 5.3 has an electronic throttle body and when it fails you will get the warning messages as well as the symptoms you are getting. The fix is in most cases is going to require having to replace the throttle body assembly.

About how much does that costCan I get by with just replacing the sensor switchFor a temporary fix
Automotive Expert
The labor to remove and replace the throttle body call for .5 of none hour and they will most likely want to diagnose it for about one other hour in labor so you're looking at 1.5 in labor and a new OEM throttle body list for $321.88. This price may vary a little as well depending on market pricing in your area. There is no sensor that you can replace the will resolve this for you. One thing you can try first it to have the throttle body bore cleaned, there is a slight chance cleaning it will help with this code.

Is there a mechanic that can do it on side of the road
Automotive Expert
There may be, you are going to need to do a search in your area for a Mobile mechanic and see If they can come out to you. If that is not an option in your area then unfortunately you are going to need to have the truck towed.

Let me see what I can find out
Automotive Expert
Okay, hopefully, there is a mobile mechanic available and can help you out with this, nothing worse them being stranded on the road.

Yeah especially when it's a little cold outside
Automotive Expert
For sure, stay safe.

Thanks
Automotive Expert
You're very welcome,Stacy! Glad I could be of some help today! I hope everything works out well for you! If there are any additional questions on this issue that should arise, please feel free to reply and ask! Have a great day!

Wanna tell Ron the technician that I chatted with on here, thanks man. I was able to find a throttle body and I changed it out myself on side the road.! Your help was extremely helpful. Thanks again
Automotive Expert
Great Stacey, glad to hear you got this resolved, and thank you very much as well. Have a safe trip.

Still not sure what you need?

Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
