Bank 1 Sensor 2: The sensor has been one of the important components in vehicles that react in the face of physical stimuli. The sensor will check and measure each physical stimulus as an input parameter; then it will send electrical signals that can be measured as an output.
In machines with injection systems, the functions of the central computer are performed by a device called an ECU. This is responsible for receiving sensor signals.
The sensor is also an important component of the vehicle pollution control system.
With the help of this device, the composition and fuel and air will be optimized and will be very effective in the operation of the car engine.
The sensor will reduce emissions and make the engine more efficient.
Bank 1 sensor 2 location (Where is bank 1 sensor 1 located)
The car’s oxygen sensor is located in the front or upper hand of the catalyst, which is according to the engine’s first cylinder.
Bank 1 is the representative of cylinder 1 of the engine, while sensor 1 will act as the upper hand sign. Car O2 sensor (Bank 1, sensor 2) rear or lower hand catalyst converter is located in the bank, which is according to the first engine cylinder.
Bank 1 is a representative of cylinder 1 engine and the sensor is only as a downstream designation.
Bank 1 sensor 2 upstream or downstream ?
Upstream and downstream orientation are used to name vehicle oxygen sensors. In most cases, the exhaust of the vehicle has 2 independent oxygen sensors, one of which is placed before the input of the exhaust catalyst (upper hand), and the other is placed behind the catalyst (lower hand).
More simply, the up and down sensor will be used to describe the position of the vehicle’s oxygen sensor to the exhaust catalyst, according to the direction of the exhaust smoke particles.
To better understand the car’s exhaust, compare it to a flowing water atmosphere. The car catalyst converter after the “high” oxygen sensor fits a certain motor Bank Number and before the “low” bank sensor in the same part.
Bank 1 sensor 2 Symptoms
In most cases no more than 2 oxygen sensors are available in any bank. All engines require only one oxygen sensor at the end of each catalyst.
As a result, “V” configuration engines are generally used from 4 separate Oxygen Sensors to indicate the performance of the PCM/ECM. Engines with 4 cylinders are almost always alone, using 2 separate oxygen sensors.
Pick-up engines have only one engine Bank, and as a result, they use a catalyst. That means that only one upper-hand oxygen sensor and one lower-hand O2 sensor are enough for them.
P0137 bank 1 sensor 2
The P0137 has been a fault code in the oxygen sensor indicating that, oxygen No. 2 located along bank 1, produces less voltage than expected.
This code corresponds to oxygen sensor No. 1. In general, this voltage should be below 450 MV for 20 seconds or a little more.
This indicates that the O2 #2 sensor of the engine cannot give good feedback to the engine ECM. Due to the fact that the No. 2 oxygen sensor is located at the bottom of the vehicle catalyst converter, the car engine cannot determine the values of the lower exhaust hand.
As a result, the engine management software cannot succeed in obtaining a good and accurate picture of the combustion efficiency in the damaged Bank.
Common Signs code P0137:
- Check the engine light.
- Excessive smell of exhaust
- Possible leakage in the exhaust
- Irregular or violent unemployed
- There was no power to accelerate.
P0326 knock sensor 1 bank 1
The p0326 error means that “the signal of the sensor has seen a blow outside the range“. The engine ECM will easily detect sensor failure due to short or open connection after checking the analog input signal from the sensor within the necessary range.
When the difference between the signal of the impact sensor and the noise level is less than necessary, the error p0326 is seen.
Of course, if the signal value is greater than the permitted value, this error code will be displayed again.
The error p0326 in ECM memory can be shown for one of the following reasons:
- Bad and wrong call.
- Short connection in the car explosion or tear chain gauge
- Shock sensor failure
O2 Bank 1 Sensor 2
The oxygen sensor is placed near the catalyst after the catalyst, also known as The O2 Bank 2 sensor or Sensor 2 sensor. It is also responsible for monitoring the function of the catalyst and controlling the oxygen left in the gases that come out of it.
If the O2 sensor for bank 1, sensor 2 has a problem, the P0138 error is displayed in the ECU.
This sensor is tasked with analyzing the vapors that come out of the catalyst converter. You need to be careful not to get too much voltage into your oxygen sensor.
In this case, more fuel will go into the engine than air.
P0150 Bank 2 Sensor 1 Location
When you see the P0150 error code, you should notice that the oxygen sensor is malfunctioning.
When the Oxygen Sensor has a problem, the Voltage that goes to the electronic control unit in the parameter section remains constant on 449 or 459 MV. This number will be constant without changing the device.
If your device is in good health, the voltage sent by the oxygen sensor to the electronic control unit will be about 50 to 900 MV (constantly changing).
