[SOLVED] P119F Code: Fix High Voltage Nox Sensor 2 Signal Circuit

The automobile fault code P119F indicates a problem with the Nitrogen Oxides (NOx) Sensor 2. This can be identified by the Engine Light or Service Engine Soon Warning Light being illuminated. The possible causes include a faulty sensor, an open or shorted harness, or a poor electrical connection in the sensor circuit.

To fix this issue, it is recommended to visually inspect the wiring harness and connectors for any damage.

Additionally, check for broken, bent, pushed out, or corroded pins in the connectors. The repair time for this fault code is estimated to be around 1.0 hour.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p119f fault code.

  • The symptoms of the automobile fault code p119f include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p119f can be caused by a faulty NOx Sensor 2, an open or shorted harness, or a poor electrical connection in the circuit.

  • The fault code P119F can be caused by the following: 1.
  • Faulty Nitrogen Oxides (NOx) Sensor 2.
  • 2.
  • Open or shorted harness of Nitrogen Oxides Sensor 2.
  • 3.
  • Poor electrical connection in the circuit of Nitrogen Oxides Sensor 2.

To fix the automobile fault code p119f, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p119f, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p119f are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P119F fault code indicates a high voltage signal in the NOx Sensor 2 circuit. NOx sensors are part of the selective catalytic reduction system, which reduces NOx emissions in diesel engines.

There are two NOx sensors, one upstream and one downstream of the selective catalytic reduction system.

These sensors are connected to the control module via CAN and exchange information through it. The NOx sensors have a sensing cell, a pumping cell, and a heater. The sensors maintain a constant reference voltage across the sensing cell and control the pump current through the pumping cell.

The amount of current required is proportional to the concentration of NOx in the exhaust. If the ECM detects a fault in the NOx sensor circuitry or a performance fault for more than 2 seconds, it sets the P119F fault code.

This fault code indicates a high voltage signal in the NOx Sensor 2 circuit.

What are the possible causes for the automobile fault code p119f?

If you see the engine light or service engine soon warning light on, the fault code P119F could be the culprit. This code is often caused by a faulty Nitrogen Oxides (NOx) Sensor 2, an open or shorted harness, or a poor electrical connection in the NOx Sensor 2 circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes listed above for a comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the fault code p119f?

To fix fault code p119f, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. This can help identify any issues with the Nitrogen Oxides Sensor 2 harness, such as an open or shorted circuit or poor electrical connection. By checking these possible causes, you can take the necessary steps to resolve the problem and get your engine running smoothly again.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p119f?

When resolving the fault code p119f, start by checking for damaged components and connector’s pins. Visually inspect the related wiring harness and connectors, looking for any signs of damage such as broken, bent, pushed out, or corroded pins. This can help identify if the issue lies with a faulty Nitrogen Oxides (NOx) Sensor 2, an open or shorted harness, or a poor electrical connection in the Nitrogen Oxides Sensor 2 circuit. Take note of any findings to determine the appropriate fix.

p119f error fault code explained

If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to a faulty Nitrogen Oxides (NOx) Sensor 2. To fix this, visually inspect the wiring harness and connectors for any damage.

Also, check for broken, bent, pushed out, or corroded connector pins.
