CEL P1135 (do I have to?)

On my way home from work the other day my check engine light came on. The next day I had it at the mechanic to see what that was all about. They came back with a code P1135: Manufacturer's Controller Air & Fuel Metering Air/fuel sensor heating circuit (reading off the estimate) for ~$300. My question is: what happens if I don't have this done (short-term and long-term)? I'm not too up on these things, so to me "sensor" just tells me that it's monitoring something and not actually DOING anything...therefore it's probably fine, although if the air/fuel ratio became an issue somehow, I'd be in trouble. Please enlighten me...it's a good amount of dough for me right now. Thanks!

It probably IS doing something but see below.

MAKE, MODEL, ENGINE OPTIONS OF VEHICLE PLEASE!! ALSO EMISSIONS LAWS -- DEPENDS WHERE YOU LIVE.

Specific advice might be available if these were provided. I might also be able to tell you if the estimate is reasonable. Without the vehicle information a reply cannot be very useful.

Oops, sorry...

2000 Toyota Camry LE 4 cyl. I live in Rhode Island. The estimate on the sheet says $280 but I could've sworn they said it would be $375. Maybe they do their estimates without labor included or maybe I misheard. Thanks for any information you can give me.

Are you subject to smog inspection there?

That is about what I would charge for replacement, clearing the code and a test drive.

This is one code that pretty much tells you what part to replace. I have never seen a heater circuit code that wasn't a bad O2/air fuel ratio sensor. Maybe on European cars that I don't work on its different but on Japanese if you get a heater code replace the O2 sensor and the problem will be fixed. An air/fuel ratio sensor is a new generation more sophisticated variant of an O2 sensor. With a burnt out heater it will not function well particularly during warmup and at low throttle openings. The computer will have difficulty keeping the fuel mixture optimized for economy and cleanest possible exhaust.
