P2135 Code

[Geo]

Bleh! Not sure if I need my TB replaced or what. going to get it further checked next week. Anyone else had this error code before?

Do you do any DIY? I haven't had this code myself, but it's a throttle position sensor-related code, so the automatic first thing to do is clean the throttle body. Lots of oil-based gunk accumulates in the TB over time and mucks up the works. The TPS should also be removed from the TB and cleaned separately. This is a very reasonable DIY job. It's somewhat slow and tedious because of the limited access, but nothing at all difficult or technical. If you don't DIY, take it to a good shop and request that the TB and TPS be cleaned with throttle body cleaner. Not sure what this would cost - hopefully no more than 1/2 hour labor (no parts). Then, if that doesn't get rid of the code, I would replace the TPS next (around $35).

Yea, I'm a DIY guy. The thing is, I had the throttle body cleaned about a year or so ago, should I just clean it anyway?

Yes, get in there yourself with rags and throttle body cleaner. And definitely remove the TPS, clean it, and check the wires and connector halves for corrosion/damage. You will need to use a very short, or angled screwdriver. If doing all of that doesn't kill the code, I would hang a new TPS on for $35 (or do it the right way and test the part first if you can find the specs). These throttle bodies aren't like the newer ones where none of the sensors can be replaced. Shouldn't be any reason to replace the TB on the '06, unless it somehow cracked.
