Upstream Vs Downstream Oxygen Sensor
Upstream Vs Downstream Oxygen Sensor. Front can be o2 or afr sensor, both of which are o2 sensors, narrow and wideband respectively. The bank that contains cylinder one is bank one.
On this video i will explain the difference between the upstream and downstream oxygen sensors on your car, specially when you order it from the part store t. The number and location of the oxygen sensors are specific to every vehicle’s year, make and model. Locate your vehicle's firing order diagram.
Upstream Oxygen Sensors Are Located In Between The Engine And The Catalytic Converter.
Don't know if the part numbers are the same for an 05 but wouldn't be shocked if they are the same. The sensors have four different individual part numbers. Downstream oxygen sensors are located in the catalytic converter or farther away from the engine than the catalytic converter.
Since The Downstream Sensor Comes After The Catalytic Converter, It Sees Cleaned Exhaust;
The bank that does not contain cylinder one. Sensor 1 is the sensor closest to the engine. The downstream oxygen sensor is located directly after the catalytic converter.
Sensor 1 Is The Upstream Oxygen Sensor.
They both function the same but are different enough that they cannot be swapped. Rear sensor is only to monitor cat efficiency. The bank that contains cylinder one is bank one.

If you're having fuel issues in closed loop it is likely your front o2 sensor. The major difference between upstream and downstream oxygen sensors is that the former (upstream) is installed before the catalytic converter, while the latter (downstream) is installed behind/after the cat, just before the muffler or resomer. P0135 o2 sensor heater circuit malfunction (bank 1 sensor 1).
The Upstream Oxygen Sensor Is Located Before The Catalytic Converter.
Also, should i assume the o2 sensor needs. If the data between the two sensors becomes more similar, the vehicle's computer may trigger a. Is it the upstream one at the manifold or the downstream catalytic converter?
