What does Bank 1 mean on a ho2s heater?

What does Bank 1 mean on a ho2s heater?

Bank 1 refers to the side of the engine that has the #1 cylinder. Bank 2 is the opposite side of the engine. If you’ve got a four-cylinder, there will only be one bank. The related code for the other bank is P0161 HO2S Heater Performance Bank 2 Sensor 2. This indicates the PCM has detected a problem with the bank 2 downstream oxygen sensor heater.

When to replace Bank 1 HO2 sensor 1?

If HO2 Sensor itself appears to have been damaged, replace it. If a visual inspection reveals no obvious problems, viewing the faulty heater circuit on a scan tool may reveal if the fault is currently occurring. If the scan tool datastream shows that the Bank 1,1 heater element is pulling 0 amps then suspect an open in the circuit.

What does Bank 1 mean on an oxygen sensor?

This indicates the PCM has detected a problem with heater circuit of the downstream oxygen sensor. Bank 1 refers to the side of the engine that has the #1 cylinder. Bank 2 is the opposite side of the engine. If you’ve got a four-cylinder, there will only be one bank.

What does the p0032 code in ho2s mean?

P0032 is triggered when the PCM detects a problem in the operation of the heater element of an oxygen sensor located in Bank 1, the side of the engine with cylinder #1. What Does the P0032 Code Mean?

What does Bank 1, sensor 2 on ho2s do?

The job of the HO2S is to read the oxygen content of the exhaust system and send that information to the PCM. The Bank 1, Sensor 2 refers to Bank 1’s second sensor on the back. The PCM will then use the information to monitor the catalytic converter’s efficiency.

Why is my ho2s sensor not sending the correct data?

The most common cause of this error code is that, the HO2S bank 1, sensor 2 (located at the back of the catalytic converter of the engine) is unable to send the correct data to the PCM, which may suggest damage or a defect with the sensor. The sensor may have a bad internal heater element.

Where is the bank 2 oxygen sensor located?

Bank 2 is the side of the engine that does not contain the #1 cylinder. The oxygen sensor 2 located on this bank is also known as the downstream oxygen sensor because it is located after the catalytic converter.

What is the error code for ho2s heater?

Error Code P0037 is defined as (HO2S) Heated Oxygen Sensor Heater Control Circuit Low, Bank 1 Sensor 2. This refers to a problem with the heater element circuit of the HO2S.
