Ok, so im new here. Just looking for tips and help. I have a 2006 Lexus IS250, automatic, 164k. The "Check VSC" light is on, along with the engine light. The codes I get on my reader are :
P0172 p0175 p0101
C1201 c1223 c1241

Any insight to what might be going on with my car would be super appreciated!! Thanks in advance. 😎✌

Hi and welcome aboard. Perhaps this is just me but I would appreciate OP looking this stuff up so I don't have too. Perhaps I dislike doing more work than necessary, IDK...

However, doing this action may just help you see when codes are related to work done and maintenance that should be done. Some are brand specific so go with Toyota Lexus OBD codes.

I say this as I'm out of time to do it for you...

You can google the codes...list them and start debugging.

First set of codes. You're running rich both banks. MAF related. Start by cleaning MAF sensor. Followed by an ECU reset.

Second set of codes. Most codes are related to maybe a brake light switch.

All this can be found on Google. Search Lexus ISx50 ... followed by symptoms, or codes read.

Did you reset by scan tool, or battery, fuse's?

I'd do the fuses method. You need to reset long term fuel trims.
