What is P2047 : Engine Error code Causes Explained
This post explains the P2047 engine error code, its causes, and how to fix it. This code usually signals a diesel exhaust fluid (DEF) system fault, and fixing it helps maintain emissions performance.
How to Identify a DTCs Number
The DTC (Diagnostic Trouble Code) P2047 is related to the engine’s exhaust system, specifically the Diesel Particulate Filter (DPF) temperature sensor.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
A DTC number is usually found with an OBD-II scanner or other diagnostic equipment. The scanner displays error codes from the vehicle’s computer system when linked to the OBD-II connection. Each DTC number represents a specific issue, and P2047 covers the exhaust temperature sensor issue.
Causes of P2047 Error Code:
- Faulty Reductant Injector:
The injector may be clogged, damaged, or malfunctioning. - Open or Shorted Wiring:
Corrosion, broken wires, or loose connections in the DEF injector circuit. - Failed Reductant Control Module:
The module that controls the DEF system may be defective. - Defective NOx Sensor:
A faulty NOx sensor can send incorrect signals, triggering the code. - Blown Fuse or Relay:
Electrical supply Issues attecting the injector circuit.
Risk Level of P2047 Error Code:
The risk level of P2047 is Medium, When a “Medium Risk Level” is assigned, it usually means that the issue could lead to moderate performance degradation but is not an immediate danger to engine operation.
Common Car Brands Affected by P2047 Code:
The P2450 engine error code is commonly found in the following list.
- Ford
- RAM
- Smart
- Chevrolet
- Dodge
- Mercedes
- BMW
