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 is the engine code for a ho2s heater?
Replace and re-check. Engine codes P0135 (HO2S Performance Bank 1 Sensor 1) and P0030 (HO2S Heater circuit Bank 1 Sensor 1). I replaced the upstream oxygen sensor (bank 1 sensor 1) with an NGK 21546 however the MIL is still on.
Where are Bank 1 and 2 O2 sensors located?
Summary. If your DTC code says: Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after the catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
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.
What does sensor 1 mean on ho2s heater?
HO2S Heater Control Circuit Bank 1 Sensor 1 is the generic definition for the P0030; however your vehicle’s manufacturer may have a different definition and information for the P0030 code. What does this mean? Cost of diagnosing the P0030 code Labor: 1.0 The cost of diagnosing the P0030 code is 1.0 hour of labor.
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 is the PCM code for ho2s heater?
The code P0032 is set by the PCM when it detects that the heater control circuit exceeded its high voltage limit. This error code is similar to codes P0031 (HO2S Heater Control Circuit Low), P0051 (HO2S Heater Control Circuit Low), and P0052 (HO2S Heater Control Circuit High).
