Hi All,

have a 99 RX300 and the CE light came on. Went to AutoZone and got a P1131 code. They could not tell me what it meant. I searched here and cannot find it. Does anyone know what it means?

Thanks,
ed

 

P1130
Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1)
P1133
Air/Fuel Ratio Sensor Circuit Response Malfunction (Bank 1 Sensor 1)
This is from a Google Search. Looks like a A/F sensor. Denso 234-9009

 

It's interesting that you couldn't even find a P1131 code, I couldn't either. Not even on the Lexus specific codes. Something strange there.....

 

Thanks for the reply.

What makes you think P1130 is the same as 1131?

exactly...I disconnected the battery and the light is off. If it comes back on i will check it again.

Thanks for looking.
