Bank1 sensor 1 upstream 02 sensor

The bank that contains cylinder number one is bank 1. On your car bank one contains cylinders 1-3-5 and bank 2 contains cylinders 2-4-6. The 02 sensor before the CAT. is the Upstream sensor or Sensor 1. The sensor after the CAT. is the Downstream sensor or Sensor 2. Any questions please write back.

Hi Jesus, Im AL the owner of Big As Auto Repair.

If you have a 4 cylinder engine then you will only have two 02 sensors 1/1 is upstream and 1/2 is downstream. Upstream is the one closet to the engine and downstream is the one farther away from the engine.

If you have a six OR eight cylinder engine you will have four 02 Sensors. 1/1 means Bank One Sensor One. 1/1 and Bank one means right bank and right bank means the side with the number 1 spark plug. SO, 1/1 means, "Right Bank" Upstream 02 sensor. 1/2 means, "Right Bank" Downstream 02 sensor.

2/1 means, "Left Bank" Upstream 02 sensor and 2/2 means, "Left Bank" Downstream 02 sensor. Hope this helps and please visit my auto-repair-website at: http://www.bigasautorepair.com/

your truck should have four o2 sensors bank 1 sensor 1 is o2 sensor on cylinder 1 side before cat and bank1 sensor2 two is 02 sensor after cat banks 2 sensor1 is on other side berfore cat and bank2 sensor2 is after cat hope that helps when they read code it should tell you bank1 sensor1 or2 good luck

P0132 is O2 sensor High circuit sensor voltage sensor 1 bank1, What this mean is either you 02 sensor on bank1 (or where cylinder 1 is located) is disconnected internally or extenally you will need to inspect the harness for any disconnection if connection is good then you will need a new 02 sensor

On all cars, the bank 1 is where the first piston is...Your firing order on that car which is the first piston...Buy a chilton or a repair manual for your car and it will tell you which firing order your motor has....Its usually on the right hand side...Passenger side...Rule of thumb if you look at the spark plugs the one closest too you is usually the first piston....Bank 1 is located on the same side as the first piston...I hope this helps...

YOU HAVE 2 O2 SENSOR YOU HAVE UPSTREAM 02 AT EXHAUST MANIFOLD AND DOWN STREAM 02 SENSOR LOCATED IN THE EXHAUST PIPE AFTER THE CATALYTIC CONVERTER.

Hi,
Upstream Oxygen sensor low voltage output bank1. Usually a bad o2 sensor. Bank 1 is cylinders 1-3-5 and upstream sensor usually on exhaust manifold. Replacement is recommended to clear the fault....Mike

It means you need to replace the upstream o2 sensor. The heater is bad in the sensor.

1/1 is upstream sensor on the number 1 cylinder side, 1/2 is the downstream of the number 1 cylinder side, 2/1 is the upstream of the number 2 cylinder side, 2/2 is the downstream of the number 2 cylinder side. Hope this helps.
