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.
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 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.
September 16, 2020 P0120 Code: Throttle/Pedal Position Sensor “A” CircuitA TP sensor measures your throttle blade opening. The number of TP sensors may vary depending on your vehicle’s make and model. For example, older vehicles that have mechanical throttle linkage are equipped with only one TP sensor. On the other hand, vehicles with electronic throttle control (ETC) are equipped September 16, 2020 P0715 Code: Input/Turbine Speed Sensor “A” CircuitError code P0715 is a generic trouble code, so it is supported in various makes and models. However, keep in mind that the repair and diagnostic procedures for each may vary depending on the specific vehicle you own.
September 16, 2020 U0073 Code: Control Module Communication Bus “A” OffNote: The definition of code U0073 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
