To fix the automobile fault code p119d, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p119d, 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 diagnosis and fixing cost of the automobile fault code p119d are the estimated repair time and the hourly rate charged by auto repair shops. The estimated repair time for this fault code is 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p119d fault code.

The P119D fault code refers to a problem with the NOx Sensor 2 Signal Circuit in the selective catalytic reduction system of a diesel engine. This system is responsible for reducing nitrogen oxide emissions. There are two NOx sensors in this system, one placed upstream and one placed downstream of the selective catalytic reduction device.

These sensors measure the concentration of NOx in the exhaust gases. The NOx sensors are smart sensors that perform electrical monitoring inside the sensor itself.

They send the results to the Engine Control Module (ECM) via a CAN connection. The NOx sensor contains a sensing cell, a pumping cell, and a heater.

The sensing cell measures the concentration of NOx in the exhaust gases, while the pumping cell controls the pump current to maintain a constant voltage in the sensing cell. If the ECM detects a fault in the NOx sensor circuitry or a performance fault in the NOx sensor for more than 2 seconds, it will set the P119D fault code.

This code indicates a problem with the NOx Sensor 2 Signal Circuit. It is important to address this fault code promptly to ensure proper functioning of the selective catalytic reduction system and to reduce nitrogen oxide emissions.

What are the possible causes for the automobile fault code p119d?

If you see the engine light or service engine soon warning light on, the fault code P119D 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 p119d?

If you’re dealing with the fault code p119d and your engine light is on, it’s time to take action. The cause could be a faulty Nitrogen Oxides (NOx) Sensor 2 or issues with the wiring harness and connectors. To fix this, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This step is crucial in identifying any issues and getting your engine back on track.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p119d?

When troubleshooting the fault code p119d, which is indicated by the Engine Light or Service Engine Soon Warning Light being ON, it is important to check for damaged components and connector’s pins. This fault code is commonly caused by a faulty Nitrogen Oxides (NOx) Sensor 2, an open or shorted harness, or a poor electrical connection in the Nitrogen Oxides Sensor 2 circuit. To resolve this issue, visually inspect the wiring harness and connectors, paying close attention to any signs of damage such as broken, bent, pushed out, or corroded pins.
