My girlfriend took her fit into the dealership because her check engine light was on. Code P0135 came up for the A/F Sensor Heater Circuit. They quoted her about $550 to replace it. Now I am stuck with an upset girlfriend because she recently bought this car. I have searched the forums and this seems like a common issue with these vehicles. She has a 07 with 80,000kms.
Has anyone had luck in cleaning these sensors? Or should I go buy one for $200 and pop it in myself?
I have never worked on a little import, but I imagine replacing an 02 sensor doesn't cost $200-$300 in labor.
Also, she is away so I haven't had a look as to where it is. Does anyone have an approximate location or better yet a picture?

 

Labor costs for an 02 sensor or AF sensor is always WAY overpriced. It'll take about 5 minutes and you will need a special tool (it's a deep socket with a cut down the side). The tool is cheap and available at any auto-parts store. I usually find good prices on these sensors at Sparkplugs.com. Be sure to get the right one.... i want to say there are two on the Fit.

 

or an open ended 7/8" wrench. i just had this same code a week ago. sensor from dealer cost $270 plus tax(that is list). i paid much less. changed it myself took about 30-45 min with the 2.5" exhaust and the turbo piping in the way. if it was stock would have been a lot faster. cleaning it wouldnt help. part would still fail if not be worse.
