The automobile fault code P11C0 indicates a problem with the Nitrogen Oxides (NOx) Sensor 2. The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.

The cause of this fault code can be a faulty NOx Sensor 2, an open or shorted harness, or a poor electrical connection in the NOx Sensor 2 circuit. To fix this issue, you should visually inspect the wiring harness and connectors for any damage. Look for broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour.

It is important to address this problem promptly to ensure optimal engine performance and emissions control.

The factors influencing the cost of diagnosing and fixing the automobile fault code p11c0 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 p11c0 fault code.

The P11C0 fault code refers to a high voltage issue in the O2 reference voltage circuit of NOx Sensor 2. NOx sensors are part of the selective catalytic reduction system used to reduce NOx emissions in diesel engines.

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

These sensors measure the concentration of NOx in the exhaust gas. The NOx sensors are smart sensors that perform electrical monitoring internally and send the results to the Engine Control Module (ECM). They consist of a sensing cell, a pumping cell, and a heater.

The sensing cell maintains a constant reference voltage, and the pumping cell controls the pump current to maintain this voltage. The amount of current required is proportional to the concentration of NOx in the exhaust. In the case of the P11C0 fault code, there is a high voltage issue in the O2 reference voltage circuit of NOx Sensor 2. This means that the voltage in the circuit is higher than expected.

The ECM detects this fault and sets a Diagnostic Trouble Code (DTC).

The DTC will be set if the fault persists for more than 2 seconds. It is important to address this issue to ensure proper functioning of the NOx sensor and the selective catalytic reduction system.

What are the possible causes for the automobile fault code p11c0?

If you see the engine light or service engine soon warning light on, the fault code P11C0 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 Nitrogen Oxides 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 p11c0?

If you’re dealing with the fault code p11c0 and your engine light is on, it’s time to visually inspect the wiring harness and connectors. This could be caused by a faulty Nitrogen Oxides (NOx) Sensor 2, an open or shorted harness, or a poor electrical connection in the circuit. To fix it, check the possible causes mentioned earlier and give the wiring harness and connectors a thorough visual inspection. Look out for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p11c0?

When resolving the fault code p11c0, 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 connection. This will help you determine if the fault lies in a faulty sensor or a poor electrical connection.
