What does code P015A mean?
What does OBD-II fault code P015A mean? OBD-II Code Decreased engine performance is defined as a O2 Sensor Delayed Response – Rich to Lean. The purpose of the oxygen sensor is to measure the oxygen content in the exhaust gases after they leave the combustion process of the engine.
How do you fix a delayed O2 sensor?
How To Correct P013E O2 Sensor Delayed Response – Rich to Lean (Bank 1 Sensor 2)
- Replacing of faulty Heated Oxygen Sensor.
- Repairing the broken, damaged and burnt circuit wiring of the sensor.
- Effectively checking the troubleshooting ECM/PCM and replacing the components if needed.
How do you fix p015b?
Usually just replacing the O2 sensor will take care of this issue; if it doesn’t, further testing will be necessary. Again, if you’re not familiar with auto repair, it is best to bring your vehicle to an auto repair shop.
What causes slow response from O2 sensor?
The slow response of an O2 sensor may be due to a sensor that is just getting old and over time may get contaminated with time with carbon and other contaminants that deteriorate the sensor over time.

What causes P0106 code?
Diagnostic trouble code (DTC) P0106 stands for “Manifold Absolute Pressure/BARO Sensor Range/Performance.” This code triggers when the powertrain control module (PCM) receives erratic MAP/BARO sensor readings.
What is code P0139?
Diagnostic trouble code (DTC) P0139 stands for “O2 Sensor Circuit Slow Response (Bank 1, sensor 2).” It indicates that the powertrain control module (PCM) has detected a potential issue with the signal from the rear oxygen sensor on bank 1.
What is P0521 engine code?
Engine code P0521 is defined as the “Engine Oil Pressure Sensor/Switch Range/Performance” error code. This diagnostic code is a generic OBD-II powertrain code triggered when there’s a problem with the engine oil pressure or oil pressure gauge readings.
