Obd2 Code P0131

1 or improper air fuel ratio. What the P0131 code means P0131 is telling us there is a fault in the oxygen sensor, located in the bank 1 sensor 1 location of the vehicle. This is also called air/fuel sensor, or heated O2 sensor. This means that the ECU has detected either improper voltage from the oxygen sensor or improper air-fuel ratio. Bank 1 is referring to the left side of the engine, when sitting in the drivers seat. Sensor 1 is referring to the sensor located before the catalytic converter in the exhaust system. What causes the P0131 code? P0131 can be caused by a variety of issues: Failed Oxygen sensor Damage or unplugged wiring Open or short Improperly reading coolant temp sensor Failed heater circuit for oxygen sensor Most commonly the sensor has simply failed due to age and wear What are the symptoms of the P0131 code? When a fault is detected in the oxygen

OK, in plain English, a P0131 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 1) diagnostic trouble code (DTC) is telling you: That the upstream oxygen sensor (located before the catalytic converter) is reporting a low voltage to the PCM (Powertrain Control Module). This continuous voltage will be a value under .5 Volts (500 millivolts). To be a bit more specific, this ‘stuck’ voltage will be a value between .1 Volt to .5 Volts (100 to 500 millivolts). Normally, any continuous voltage, from the upstream O2 sensor, below .5 Volts indicates a Lean condition... but not always, since the O2 sensor can fail and produce the same result (although a Lean condition does not really exists) A Lean condition simply refers to the fact that the engine's air/fuel mixture is too oxygen heavy (in other words, not enough fuel is present for proper/ideal combustion). Remember, in a normally operating engine, the front (upstream) O2 sensor will produce a voltage that will constantly change between .1 Volt to .9 Volts DC. When a P0131 pops up, the PCM is seeing a voltage that stays continually fixed somewhere below .5 Volts. This could be caused by a: BAD oxygen sensor. The oxygen sensor fails internally in such a way that it stays stuck producing a continuous low voltage. This low voltage will be something below .5 Volts (500 millivolts). A lean condition due to a: Failing fuel pump. Dirty fuel filter. Clogged fuel injectors. Vacuum leak from bad intake manifold gaskets (these are made of plastic) or a vacuum hose(s). In the next section I'll show you how to diagnose this trouble code and find out if the upstream (bank 1 sensor 1) oxygen sensor is the one behind it.
