Also, verify whether or not the heating control system is intact. If it is intact, the oxygen sensor must be replaced. Replace the oxygen sensor in case of infinite resistance.HO2S2 (B1) (O2 sensor circuit high voltage bank 1 sensor 2) A: An excessively high voltage from the sensor is sent to ECM: B: The minimum voltage from the sensor is not reached to the specified voltage.What the P0050 code means. This code is found when the Engine Control Module (ECM) has detected an issue with the heater control circuit for the bank 2, sensor 1 oxygen sensor. The heater circuit is used by the ECM to heat the oxygen sensor to proper operating temperature for an accurate reading. This code may be seen with P0051 and P0052.What the P0042 code means. The heated oxygen sensor’s heater circuit is controlled by the car's engine control unit (ECU). P0042 tells us there is an issue between the ECU and the oxygen sensor bank 3 sensor 1. This heating element is required for proper sensor readings.Hi, need to replace 2 O2 sensors on bank 1, can't figure out if they're the ones before or after the catalytic converter. The Infiniti part numbers are HO2S1 - B1 front O2 sensor, and HO2S2 - B1 rear … read moreDiagnostic trouble code P0139 indicates that the powertrain control module (PCM) has detected a potential issue with the signal from the rear oxygen sensor on bank 1. The rear sensor is located behind the catalytic converter, and bank 1 refers to the side of the engine that houses the #1 cylinder. In GM automotive terminology, "cross-counts ...P0038: HO2S Heater Control Circuit High Bank 1 Sensor 2. Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).P0030 Trouble code definition. P0030 is the code for HO2S Heater Control Circuit (Bank 1 Sensor 1) What the P0030 code means. P0030 indicates for the engine to operate properly, the engine exhaust should have a specific air-fuel ratio of 14.7 to 1 as determined by the heated oxygen sensors (HO2S) which detect the oxygen content of the exhaust.To diagnose the P0054 Ford code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.Diagnostic trouble code (DTC) P0052 code stands for “HO2S Heater Circuit High Voltage (Bank 2, Sensor 1).”. This code is set when the powertrain control module (PCM) detects that there is a mismatch between the desired and actual state of the control circuit of the heated oxygen sensor (HO2S) 1 on bank 2. This code may also be taken to mean ...Bank 1, Sensor 2 is the downstream oxygen sensor in the exhaust behind the catalytic converter. The engine bank that contains cylinder 1 is called Bank 1. V6 and V8 engines have two banks and two catalytic converters, one for each. In such cases, the bank that contains cylinder number one is called “Bank 1.”.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.
