This error code indicates that the aftertreatment outlet NOx sensor is unable to accurately measure the nitrogen oxides (NOx) levels in the exhaust after it has passed through the emission control system. This issue can compromise the vehicle’s ability to meet emissions standards and may affect overall engine performance and efficiency.

This code is set when the aftertreatment outlet NOx sensor reports inaccurate measurements of NOx levels in the exhaust gases after they have passed through the emission control systems. This sensor is critical for verifying the effectiveness of the engine’s aftertreatment strategies.

This error indicates a communication issue between the ECU and the aftertreatment outlet NOx sensor, leading to an inability to receive data. This problem could be due to faults within the CAN Bus system, such as broken wires, poor connections, or faulty CAN Bus hardware.

This diagnostic trouble code is activated when the aftertreatment inlet NOx sensor reports a problem with its ability to measure nitrogen oxides in the exhaust gases accurately. This sensor is crucial for assessing the effectiveness of the engine’s emission control system before the gases pass through any aftertreatment systems.

This diagnostic trouble code is triggered when the temperature sensor in the Diesel Exhaust Fluid (DEF) tank detects an issue with accurately measuring the fluid’s temperature. This problem can affect the DEF dosing system, which is critical for maintaining the correct emissions control through selective catalytic reduction.

This diagnostic code signals that the resistance in the circuit to the second injection valve is below the normal range, indicating a short to ground. Such a condition can lead to excessive current flow through the circuit, potentially damaging the injection valve or related electronic components.
