passenger side, the sensor closest to the engine
This is incorrect. Bank 2 is on the -drivers- side of this vehicle. On this 4 liter SOHC motor Bank 1 is on the same side where the #1 cylinder is located,which is on the -passenger- side. I found this out the hard way . After reading this posting, I replaced the O2 sensor on the passenger side of my 98 Explorer. It didn't change anything. After reading a posting elsewhere and many hours of diagnostics, I switched the O2 sensor to the drivers side,and reset the computer. Check engine light has been off ever since.
Bank 1 is the passenger side of the engine Sensor 2 is after the exhaust gas has passed through the catalytic converter ( downstream )
