Check Engine Light/o2 Sensor
Hi everyone,
I'm a new sc430 owner and I love my car to death. My car is pretty much mint except the check engine light is on. (bought it like this).
Anyway, I brought my car to my buddys garage so that he could plug in the OBD 2 unit in to see what was wrong. The code P0155 came up "O2 sensor heater circuit bank 2, sensor 1"
Ive already bought the sensor, but I have no idea where the sensor should go. All this "upstream"/ "downstream" stuff is really confusing. I just want to know exactly where the sensor is so I can replace the bad one.
If anyone has like pics or anything, or experience on this, any info would greatly be appreciated!
Thanks,
Mike

There are 4 O2 sensors : 2 sensor1s before CAT and 2 sensor2s after CAT , band 1 on driverside and band 2 on passengerside . Your band 2 sensor 1 locates on passenser side and before Catalytic converter . That's all i learned from Master Pearlpower
