1999 Lexus GS300 Oxygen Sensor

Asked by MQUINIC Oct 25, 2010 at 09:49 PM about the 1999 Lexus GS 300 RWD

Question type: Maintenance & Repair

Would any of you happen to know which oxygen sensor is the "Bank 1" oxygen sensor and the exact location of it? I'm pretty sure that it is one of the sensors located within the engine bay, before the catalytic converter, but do realize that my car has 4 different oxygen sensors. Thanks

it is located on the tailpipe just before it connects to the exhaust manafold,if you getting a bank 1 reading,you should have all of them replaced.
