The automobile fault code P11D5 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.

P11D5 Fault Code: Understanding The Description And Troubleshooting Steps
The P11D5 fault code indicates that the NOx Sensor 2 has exceeded the minimum learning limit. This sensor is part of the selective catalytic reduction system, which is used to reduce NOx emissions in diesel engines. There are two NOx sensors, one upstream and one downstream of the selective catalytic reduction system.
They are connected to the control module via CAN and exchange information through it. The NOx sensor is a smart sensor that performs electrical monitoring inside the sensor and sends the results to the Engine Control Module (ECM). It contains a sensing cell, a pumping cell, and a heater. The sensing cell measures the concentration of NOx in the exhaust gas, while the pumping cell controls the pump current to maintain a constant voltage in the sensing cell. When the ECM detects a circuit or performance fault in the NOx sensor for more than 2 seconds, it sets the P11D5 fault code.
This means that the NOx Sensor 2 has exceeded the minimum learning limit, indicating a problem with its circuitry or performance. It is important to address this issue to ensure proper functioning of the selective catalytic reduction system and reduce NOx emissions.
FAQ
If you see the engine light or service engine soon warning light on, the fault code P11D5 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 further troubleshooting.
If you’re dealing with the p11d5 fault code and your engine light is on, it’s time to take action.
