P1049 Fault Code: Understanding The Description And Troubleshooting Steps
The P1049 fault code refers to a problem with the Reductant Injector’s high control circuit in the selective catalytic reduction system. This component is responsible for dosing the reductant fluid to the exhaust gas and participating in reduction reactions.
The Engine Control Module (ECM) calculates the injection time based on NOx sensor measurements.
When the Reductant Control Module detects a short to voltage in the high control circuit, it triggers the P1049 code. This means there is a high voltage issue in the circuit that controls the reductant injector.
FAQ
If you see the engine light on or the service engine soon warning light, the fault code P1049 could be the culprit. This code is often caused by a faulty reductant injector, an open or shorted reductant injector harness, a poor electrical connection in the reductant injector circuit, or a faulty engine control module (ECM). To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken pins. It’s important to address these possible causes to resolve the fault code.
To fix the P1049 fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify if the reductant injector harness is open or shorted, or if there is a poor electrical connection in the circuit. Also, check for a faulty reductant injector or engine control module.
When resolving the P1049 fault code, start by checking for damaged components or corroded connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. These issues can cause a poor electrical connection or an open/short circuit, leading to the faulty reductant injector or a malfunctioning engine control module. By addressing these possible causes, you can effectively fix the issue and turn off the engine light or service engine soon warning light.
Wrap Up
If you’re seeing the Engine Light ON or the Service Engine Soon Warning Light, the issue could be a faulty Reductant Injector or a problem with the wiring harness or connectors. To fix it, visually inspect the wiring and connectors for any damage, and check for broken or corroded pins.
