  • 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.
  • The estimated repair time for this fix is 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p119e 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 p119e fault code.

The P119E fault code indicates a low 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 or performance issue in the NOx sensor circuitry for more than 2 seconds, it sets the P119E fault code.

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

What are the possible causes for the automobile fault code p119e?

If you see the engine light or service engine soon warning light on, the fault code P119E 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 pins in the connectors. Don’t forget to check the possible causes listed above for a more comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the p119e fault code?

If you’re dealing with the p119e fault code 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 it, 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 simple step could be the key to resolving the issue and getting your engine running smoothly again.

What should I look for when checking for damaged components and connector’s pins to resolve the p119e fault code?

When resolving the p119e fault code, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. By doing this, you can identify any issues with the Nitrogen Oxides (NOx) Sensor 2 or its circuit connections, which may be causing the Engine Light to turn on.

p119e error fault code explained

If you’re seeing 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, checking for any damage or corrosion. Look out for broken or bent pins on the connectors.
