How do I fix error P0131?

What repairs can fix the P0131 code?

1. Confirm P0131 is present with a scan tool.
2. Perform a visual inspection of the bank 1 sensor 1 wiring replacing or repairing any wiring that is found to be faulty.
3. Check voltage and resistance of bank 1 sensor 1.
4. If necessary replace the oxygen sensor bank 1 sensor 1 with a new sensor.

What causes P0131?

Code P0131 is a result of the oxygen A/F sensor incorrectly detecting the air to fuel ratio of the exhaust. This ratio is sent to the ECM which uses this data, along with comparisons to the outside air, to regulate the air to fuel ratio needed by the engine.

How many O2 sensors does a 99 Honda Civic have?

A 99+ civic is obd2b meaning it has two O2 sensors (both 2a and 2b have two).

How do I know if my O2 sensor is bad Honda Civic?

The most common signs of bad O2 sensor in Honda Civic are slow acceleration, loss of power, irregular idling, engine hesitation or jerking when accelerating, high fuel consumption, higher tailpipe emissions, foul odor from exhaust, check engine light illuminates, and sometimes stalling.

What causes low voltage O2 sensor?

The voltage output from the O2 sensor may be due to exhaust leaks causing the O2 sensors to give low output voltages. The ECM cannot correctly control the fuel-to-air ratio of the engine fuel mixture if any O2 sensor is malfunctioning.

How do you fix a low voltage O2 sensor?

Repair any exhaust leaks before the sensor to prevent excess oxygen getting into the exhaust stream causing the low voltage readings. Check the O2 sensor for oil or coolant contaminants that could foul the sensor. Repair any harness that is damaged properly to prevent erratic readings from the sensors.

Where are the o2 sensors located on a Honda Civic?

Identification. If you open the hood of your Honda Civic, most likely you will locate the oxygen sensor (O2) mounted in the exhaust manifold, above the exhaust pipe flange. On some models the exact location might vary, but you can always find the sensor by following the exhaust manifold and pipe.
