Cel P1155


Recommended Posts

2000 RX-300 with approx. 65K on the clock........

I have a CEL that is showing P1155 This, according to a chart I found, is bank 1 sensor 1....... I am ASSUMING (and we all know what happens when you do THAT!) That this is an O2 sensor. Can someone verify that 1)this is actually the problem, 2) which sensor this is actually referring to and it's location, and 3)if there is a Toyota part that will cross-over and cost less?

If there is not a Toyota part, should I get a dealer O2 sensor? or will a Bosch part work just as well. I have found prices ranging from 65 bucks (no connector, you splice in your old one) to 200 bucks for a Bosch, to 335 bucks for some other brand (OEM I think)
