berry70 Posted June 5, 2007 Share Posted June 5, 2007 Hi, This is my first post on this site and i'm sure this is the right place for all my 2002 RX 300 questions. My check engine light came on yesterday along with VSC. Disconnected my battery and the EFI fuse and plugged it back in.Didn't work . Took it to autozone to read my codes. Came out with P1135 - Fuel Air Metering(that's all it said). Donno what this is and how to fix this. Any help will be really appreciated. Thanks in advance.

drinkdrive Posted June 13, 2007 Share Posted June 13, 2007 1135 is Bank 1 Sensor 1 A/F Heater circuit malfunction, its pretty common, just replace the B1S1 (manifold closest to firewall) and clear the codes. Quote Link to comment Share on other sites More sharing options...

Posted July 31, 2007 Share Posted July 31, 2007 1135 is Bank 1 Sensor 1 A/F Heater circuit malfunction, its pretty common, just replace the B1S1 (manifold closest to firewall) and clear the codes. Please excuse my ignorance, I'm a Home Theater guy and not a real car guy, but what exactly "is" a B1S1??? You say to replace it, but what is it??? Oxygen Sensor??? Thanks for any help Feel free to do this to me for such a stupid question :chairshot: Dave Quote Link to comment Share on other sites More sharing options...
