Deciphering the OBD code on my 2008 53L Chevy Silverado. 2006-2012 1998-2000 Toyota RAV4.
1 x O2 Oxygen Sensor.
Upstream 02 sensor location. 1 Typical O2 Sensor located in the exhaust manifold Fig. 2 Left and right banks of a V-type engine Fig. 3 Exhaust collector where more than 1 pipe joins together.
Here is the location of the upstream O2 sensor or Bank1 Sensor1 on a Nissan Quest. Location of downstream B1S2 B2S2 oxygen sensors on Nissan 350Z The downstream oxygen Bank 1 Sensor 2 sensor has to be accessed from underneath the engine. You will need to remove the bottom splash shield.
Disconnect the oxygen sensor electrical connectors. The upstream oxygen sensor is located before the catalytic converter. This measures the level of pollutants coming directly from the engine.
It also senses any raw unburned fuel coming from the combustion chambers. There is only 4 sensors on a 2000 dodge intrepid and the bank 2 sensor 2 is the sensor located on the right passenger side and the one located after the catalytic converter the one close to the firewall.

Im not very happy with my city mileage but great hwy. This bad boy is located before the catalytic converter and is known as O2S11 which means. Oxygen Sensor Bank 1 Sensor 1.
What does the O2 sensor do. Well in a nutshell the job of the upstream oxygen sensor is to report back to the PCM Powertrain Control Module fuel injection Computer whether its injecting too much fuel or not enough. OXYGEN SENSOR 1 2 LOCATION REPLACEMENT MAZDA 3 6 SPEED CX7 CX-7 UPSTREAM OXYGEN SENSOR DOWNSTREAM OXYGEN SENSORIn this video we will show you where the ups.
A rich fuel mixing with little oxygen in the exhaust leads to a typical voltage of 08 to 09 through the sensors platinum electrodes. A lean fuel mixture with more oxygen in the exhausts causes the voltage to drop 01 to 03 volts. WHICH OXYGEN SENSOR IS UPSTREAM AND WHICH IS DOWNSTREAMIn this video we will explain which oxygen sensor is upstream and which oxygen sensor is downstream.
Deciphering the OBD code on my 2008 53L Chevy Silverado. Bank 1 sensor 2 went out on me. Ill show you which sensor is which.
The sensor is mounted in the exhaust manifold to monitor the amount of oxygen in the exhaust. Faulty oxygen sensors cannot send the correct air-fuel ratio data to the engine control module leading to inaccurate guesses about the amount of fuel your engine needs. An upstream sensor is before the catalytic cat converter and a downstream sensor is after the catalytic converter.
Upstream oxygen sensor is also known as sensor 1 or pre-cat or upper oxygen sensor. Downstream oxygen sensor is also known as sensor 2 or post-cat or lower oxygen sensor. Downstream O2 Oxygen Sensor.
2006-2012 1998-2000 Toyota RAV4. 2006-2011 Toyota Land Cruiser. 1 x O2 Oxygen Sensor.
2007-2012 Toyota FJ Cruiser. O2 Oxygen Sensor Downstream Upstream For 2001-2004 Jeep Grand Cherokee 47L. Before you start replacing the oxygen sensor we need to identify which oxygen sensor needs to be replaced.
On 20T and 24 L four-cylinder Kia engines there are two oxygen sensors. One is upstream of the catalytic converter and one is downstream. In the following tutorial we will show you how to replace the upstream sensor Bank 1 Sensor 1.
The way you determine whether or not an O2 sensor is upstream or downstream is all done visually. Your oxygen sensor position can be determined relative to your catalytic convertor. As the name suggests upstream sensors will be located upstream or ahead of in front of above closer to the engine than your catalytic convertors.
Where is the car oxygen sensor located. Newer vehicles will have more than one sensorone upstream and one downstream of the catalytic converter. The upstream sensor will be on the exhaust pipe closer to the engine while the downstream sensor is situated closer to the muffler.
The idea is to fine-tune the input the engine computer receives by getting two readings. Sensor 2 is the downstream oxygen sensor. It is always going to be located after the catalytic converter.
Its job is to monitor the oxygen content exiting the catalytic converter in order to determine if it is operating efficiently. In some cases there will be a Sensor 3. Sensor 3 is found on some Ultra Low Emissions Vehicles and will be located after the post-catalytic converter.
