U029D: The Low Fuel Pressure System
The U029D code is related to the reductant system in an automobile. The system uses two NOx sensors to monitor the amount of NOx in the engine’s exhaust gas.
The second NOx sensor is located between the SCR and the DPF.
The ECM sets a DTC when a serial data message is received from the NOx sensor module.
The U029D code indicates a lost communication with NOX Sensor Module 1.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the u029d fault code. This code is caused by a faulty Nitrogen Oxide (NOx) Sensor Module 1, an open or shorted Nitrogen Oxide Sensor Module 1 harness, or a poor electrical connection in the Nitrogen Oxide Sensor Module 1 circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Nitrogen Oxide (NOx) Sensor Module 1. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Nitrogen Oxide Sensor Module 1 harness is open or shorted, or if there is a poor electrical connection in the circuit.
Ignoring the u029d fault code can lead to serious consequences such as reduced fuel efficiency, increased emissions, and potential damage to the engine. The faulty Nitrogen Oxide (NOx) Sensor Module 1 can cause the engine light to turn on, indicating a problem that needs to be addressed. It is important to visually inspect the wiring harness and connectors, and check for damaged components to prevent further damage to the engine.
Wrap Up
If your engine light is on, it could be due to a faulty Nitrogen Oxide (NOx) Sensor Module 1, an open or shorted harness, or poor electrical connection.
To fix it, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
