Description of DTC code P2414

The Oxygen sensor (O2) is an electronic device whose purpose is to measure the concentration of oxygen in the exhaust gases of internal combustion engines. After calculating the oxygen in the exhaust, this information is used to make the necessary adjustments to the air/fuel mixture, to obtain optimum performance of the catalytic converter (TWC), and to determine if it is working properly.

The ECM (Engine Control Module) constantly monitors the performance of the O2 Sensor. If the O2 sensor signal is found to be outside the manufacturer's specifications, the DTC P2414 OBD2 is set. This code refers to Oxygen Sensor number 1 on bank 1.

Symptoms of fault code P2414

  • Check Engine light comes on.
  • The fuel is leaking.
  • Black smoke comes out of the exhaust.

Causes of OBD2 P2414

The reasons for setting the P2414 OBDII diagnostic code are as follows:

  • Oxygen Sensor 1 circuit wires may have been damaged.
  • Possibly the O2 Sensor connector is corroded.
  • The Oxygen Sensor may be defective.
  • Perhaps there are engine vacuum leaks.
  • Fuel pressure may be outside the allowable parameters.

Possible solutions of the DTC code P2414

To troubleshoot the P2414 OBD2 fault code you must do the following:

  • Check the electrical components related to the O2 Sensor.
  • In this review, you should check that the wires do not have burn spots or wear. Due to the unfavorable location, with high temperatures and dirt, the O2 sensor tends to fail due to the poor condition of the wiring in the sensor itself.
  • To perform a visual check of each of the wires and connections leading to the oxygen sensor, and check for corrosion, short circuits, or any other damage Pay special attention to the connectors, as these usually have corrosion. Repair and replace it as necessary.
  • Make sure the electrical connections meet the minimum requirements for proper operation.
  • An important step to having a quick solution to the failure is to have the service manual of your particular model. There you will find specifications that only the manufacturer can provide.
  • Check fuel injectors and replace them if necessary.
  • Check engine coolant temperature sensor for proper operation. Purchase a new sensor if necessary.
  • Replace the Oxygen Sensor.
