The automobile fault code P11C8 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 cause of this fault code could 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, 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 issue is estimated to be around 1.0 hour.

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

The factors influencing the cost of diagnosing and fixing the automobile fault code p11c8 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 P11C8 fault code refers to a problem with the NOx Sensor 2 Heater Ground Circuit. This sensor is part of the selective catalytic reduction system, which helps reduce NOx emissions in diesel engines. There are two NOx sensors in this system, one upstream and one downstream of the selective catalytic reduction.

They are connected to the control module via CAN and exchange information through it. The NOx sensor contains a sensing cell, a pumping cell, and a heater.

The sensor measures the concentration of NOx in the exhaust gas by maintaining a constant voltage across the sensing cell.

The amount of current required to maintain this voltage is proportional to the NOx concentration.

In the case of the P11C8 fault code, the ECM has detected a high circuit ground condition in the NOx Sensor 2 Heater. This means that there is an issue with the electrical connection or the sensor’s heating element. When this fault code is triggered, the ECM sets a Diagnostic Trouble Code (DTC) to indicate the problem.

It is important to address this issue promptly to ensure proper functioning of the selective catalytic reduction system and reduce NOx emissions.

What are the possible causes for the automobile fault code p11c8 and how can I visually inspect them?

If you’re seeing the engine light or service engine soon warning light and the fault code is p11c8, there are a few possible causes to consider. One is a faulty Nitrogen Oxides (NOx) Sensor 2. Another possibility is that the Nitrogen Oxides Sensor 2 harness is open or shorted, or there may be a poor electrical connection in the circuit. To visually inspect these potential issues, check the related wiring harness and connectors. Look for any damaged components and examine the connector’s pins for any signs of being broken, bent, pushed out, or corroded.

How can I determine if the Nitrogen Oxides Sensor 2 harness is open or shorted and what should I do if it is?

If you notice that your engine light is on or you receive a service engine soon warning, it could be due to a faulty Nitrogen Oxides (NOx) Sensor 2. To determine if the Nitrogen Oxides Sensor 2 harness is open or shorted, visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. If you find any issues, it’s important to address them promptly to ensure proper functioning of the sensor.

What steps should I take to check for damaged components and inspect the wiring harness and connectors for the Nitrogen Oxides Sensor 2 circuit?

To check for damaged components and inspect the wiring harness and connectors for the Nitrogen Oxides Sensor 2 circuit, follow these steps: 1. Visually inspect the related wiring harness and connectors. 2. Check for damaged components. 3. Look for broken, bent, pushed out, or corroded connector’s pins. These steps will help you identify any issues and ensure proper functioning of the sensor.
