bongt Posted March 17, 2009 Share Posted March 17, 2009 Hi, I have a 2002 RX300 (66k miles) and got a code P1155. Just to verify - to correct the problem is to replace the sensor (part# 89467-48011) between the radiator & engine. Is this correct? any comments is greatly appreciated. Thanks.

There are two A/F sensors on that RX, one where you said and one on the on the exhaust at the firewall. I just worked on mine today and that is what I found. Hope it helps.
