P229E: Fuel Pressure Regulator 2 Control Circuit/Open
The P229E code refers to a NOx sensor circuit bank. The reductant system uses two NOx sensors to monitor the amount of NOx in the engine’s exhaust gas. The first sensor is located at the outlet of the turbocharger and monitors the engine out NOx level.
The second NOx sensor is located between the SCR and the DPF and monitors NOx levels downstream of the SCR. The ECM varies the amount of DEF or reductant added by varying the reductant injector duty cycle in response to changes in engine exhaust out NOx levels.
The smart NOx sensors consist of two components, the NOx module and the NOx sensor element that are serviced as a unit. The ECM sets a DTC when a serial data message is received from the NOx sensor module.
FAQ
If your engine light is on and you’re seeing the P229E fault code, it could be due to a faulty Nitrogen Oxide (NOx) Sensor Bank 2, an open or shorted NOx Sensor Bank 2 harness, or a poor electrical connection in the NOx Sensor Bank 2 circuit. To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector pins.
If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Nitrogen Oxide (NOx) Sensor Bank 2, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Make sure to check the “Possible Causes” listed above before proceeding with the inspection.
Ignoring the P229E fault code, caused by a faulty Nitrogen Oxide (NOx) Sensor Bank 2, an open or shorted harness, or poor electrical connection, can lead to serious consequences. The engine light will remain on, indicating a problem, and the vehicle may fail an emissions test. Additionally, the engine may experience reduced performance and fuel efficiency, and in some cases, the vehicle may even enter into a limp mode, limiting its speed and power. It is crucial to inspect and fix the issue promptly to avoid further damage and costly repairs.
