pass.side at exe manifold Bank 1 is where cylender 1 is. Bank 2 is on the other side of which is on the passenger side of the blazer. Oxygen sensor 1 is the first sensor closer to the front of the blazer. Sensor 2 would be past the catalytic converter on the same side.
The bank 1 sensor 2 on a 1996 Chevy Blazer is mounted in the exhaust. Sensor two is just behind the catalytic converter.
I have a code DTC P0154.Bank 2 Sensor 1 no activity.Which sensor is this on my 96 Blazer?
Assuming you mean bank 2 sensor 1, it would be the first O2 sensor located in the header pipe after the passenger side exhaust manifold.
O2 sensor circuit bank 1 sensor 2 no activity. Check the wiring and connections to bank 1 sensor 2 O2 sensor, if all looks good replace the sensor.
Trouble code P0135 means:O2 sensor heater circuit malfunction (Bank 1 Sensor 1)
The bank 1 oxygen sensor on a 2003 Ford Taurus is located on the motor. It is on the top, back part near the firewall.
Bank 1 would be the passenger (right) side of engine. Bank 1 Sensor 2 would be the O2 sensor after the catalytic converter on the passenger side.
driver side first o2 sensor
Bank one is the driver side on a 3.7L. There will be an upstream ( sensor 1 ) and a downstream ( sensor 2 ).
Upstream, driver side.
passenger side is bank 1 the closest to the engine is sensor 1 of the 2 on each side
