[SOLVED] P11C6 Code: Fix Nox Sensor 1 Heater Ground Circuit High!

The automobile fault code P11C6 indicates a problem with the Nitrogen Oxides (NOx) Sensor.

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, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit.

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Look out 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 P11C6 fault code refers to a problem with the NOx Sensor 1 Heater Ground Circuit.

The NOx sensors are part of the selective catalytic reduction system, which helps reduce 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 measure the concentration of NOx in the exhaust gas and send the results to the Engine Control Module (ECM).

In the case of the P11C6 fault code, there is a high circuit resistance in the NOx Sensor 1 Heater Ground Circuit.

This fault code is set when the ECM detects a fault in the NOx sensor circuitry or a performance fault in the NOx sensor for more than 2 seconds. If you encounter this fault code, it is recommended to have the NOx sensor and its circuitry inspected and repaired by a qualified technician.

What are the possible causes for the automobile fault code p11c6?

If you see the engine light or service engine soon warning light on, the fault code P11C6 could be the culprit. This code is often caused by a faulty Nitrogen Oxides (NOx) sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor 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 mentioned above for a comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the p11c6 fault code?

If you’re dealing with the p11c6 fault code and your engine light is on, it’s time to take action. The cause could be a faulty Nitrogen Oxides (NOx) Sensor or issues with the sensor’s wiring harness and connectors. To fix this, visually inspect the wiring harness and connectors for any damage or poor electrical connections. Look out for broken, bent, pushed out, or corroded pins on the connectors. Don’t delay, check these possible causes and get your vehicle back on track.

What should I look for when checking for damaged components and connector’s pins to resolve the p11c6 fault code?

When resolving the p11c6 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 harness and circuit connections, which may be causing the fault code.
