Bank 2 (sensor 1) will be upstream meaning the sensor closest to the engine on that bank... sensor 2 will always be behind / after the catalytic converter.

I have none after cat I took interior/consol out cant find any wire hook-up [all I have now is 2 one on each manifold ]


Here is where bank 2 sensor 1 is located. Sensor 1 is located upstream top of the exhaust manifold sensor 2 is after the pre-cat the photos not exactly your vehicle but very similar. NO, wires inside the car. The harnesses and connectors are under the hood.

1 more question oil indicator light is on even with wire unhooked/unhooked ecm plug under console stayed on/only goes out when dash plug unhooked [I tried 3 diff clusters]


wat color is wire at plug behind cluster so I can run new wire


didn't unhook ecm unhooked connector plug beside ecm


Most likely it is your SENDING UNIT. If your light comes on due to low pressure, it is usually way too late. They come on at around 5 psi, and at that low pressure your engine would be knocking. If you can, check the pressure with a manual gauge. If its good, go ahead and change out the sending unit. Regards


replaced unit no difference- 25lbs idle 40 lbs 2000 rpms- like I said with wire UNHOOKED lite is still on -single wire unit so to me that means wire is grounded some where [02 eclipse]
