P0036 Code: P0036 HO2S Heater Control Circuit (Bank 1 Sensor 2)
September 17, 2020
P0036 Code: P0036 HO2S Heater Control Circuit (Bank 1 Sensor 2)The downstream (post-converter) HO2S primarily gets used for post catalyst monitoring. It does this by checking the oxygen content of the exhaust gas after exiting the catalytic converter. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream.
P0431 Code: Warm Up Catalytic Converter, Bank 2—Efficiency Below Threshold
September 16, 2020
P0431 Code: Warm Up Catalytic Converter, Bank 2—Efficiency Below ThresholdCatalytic converter efficiency is monitored using upstream and downstream oxygen sensors. Most of these sensors contain zirconium dioxide-sensing elements enclosed by vented steel housings. These are connected to the lead wires in the oxygen sensor wiring harnesses via platinum electrodes. The PCM will store code P0431 if it reads that
P2198 Code: O2 Sensor Signal Biased/Stuck Rich (Bank 2 Sensor 1)
September 16, 2020
P2198 Code: O2 Sensor Signal Biased/Stuck Rich (Bank 2 Sensor 1)Identifying the underlying cause of the P2198 code can be difficult, especially if you’re not confident with your automotive knowledge. In most cases, it would be best to bring your vehicle to an auto repair shop and seek the help of a professional for an accurate diagnosis.
P0157 Code: Oxygen Sensor Circuit Low Voltage (Bank 2, Sensor 2)
September 16, 2020
P0157 Code: Oxygen Sensor Circuit Low Voltage (Bank 2, Sensor 2)The P0157 code is typically triggered when the powertrain control module (PCM) has detected that the oxygen sensor voltage stayed below the expected value for more than preset time. The voltage and timeline may differ between various makes and models.
September 16, 2020
P0422: Catalyst 2 Efficiency Below Threshold (Bank 1)The powertrain control module (PCM) tracks the switching frequency of the heated oxygen sensors 1 and 2 (front and rear sensors). A functional three way catalyst converter typically indicates a low switching frequency of heated oxygen sensor 2. The frequency increases as the converter deteriorates.
