Lit up a P1150 today which looks like the front air fuel sensor. Which is a pisser since it was just replaced under warranty 10k miles ago (warranty is expired now). Assuming I should just clear the code and see if it pop right back up. If it does just replace with an OE sensor and call it good? There is no way to try to "clean" the sensors right?

Thanks!

 

It should come off easier.

Stick with OEM and DIY.

Cleared the code took it out and ran some errands, did not come back yet. I guess I'll sit tight and maybe run some fuel system cleaner through it.

 

Hi Carguy: My 01' RX300 gives me occasional " P1150" check engine light. I reset it and its good for weeks, then pops on again. I thought it was a gas cap problem. Where is this sensor ypou talk about. ?? edvanb@hargray.com

 

It's the air fuel sensor that is in the exhaust manifold up front by the radiator. Have you tried any fuel system cleaner yet? Mine has not come back yet and I did not do anything other than reset the light.

I had the same code about 4 months ago....i reset and so far so good

 

I had the same problem so i changed the gas cap. Carl

 

Once you changed the gas cap has the CEL ever come back?
