What does P2A03 mean?
O2 Sensor Circuit Range/Performance
OBD-II Code P2A03 is defined as a O2 Sensor Circuit Range/Performance. 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. This information is critical to the PCM’s ability to maintain efficient fuel economy.
What should I do if my Nissan has a p2a03 code?
If the P2A03 code is set after a sensor is replaced, check for exhaust leaks and perform the mixture ratio self-learning procedure. What does this mean? The cost of diagnosing the P2A03 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city.
What does a p2a03 code on an O2 sensor mean?
If the upstream O2 sensor circuit fails to cycle as expected, over a set period of time and under certain programmed circumstances, a P2A03 code will be stored and a malfunction indicator lamp may be illuminated. Since a P2A03 code means that the upstream O2 sensor has failed to input an acceptable signal to the PCM, it should be considered severe.
When to use DVOM test on p2a03 sensor?
A P2A03 will be stored if there is little or no fluctuation. Connect the DVOM test leads to the sensor ground and signal wires in order to monitor live data from the O2 sensor. You may also be use the DVOM to check resistance of the O2 sensor in question, as well as voltage and ground signals.
