What does the code p2049 mean on a diesel engine?
This code indicates there is a problem with the electrical circuit that controls the reductant injector. What causes the P2049 code? The reductant, or Diesel Exhaust Fluid (DEF), is sprayed into the exhaust stream by the reductant injector system to aid in the reduction of NOx (Oxides of Nitrogen).
What does the p2047 code on a check engine light mean?
The reductant injector is used to reduce emissions gases exiting the exhaust by injecting either air or chemicals depending on the usage and vehicle. When the ECU detects the fault in the reductant injector circuit, it will set the P2047 code and the Check Engine Light will be displayed on the dashboard.
What is the diagnostic DTC for p2047?

What are all the codes on a Mercedes Benz?
Use an advanced OBD-II code reader to read and erase Engine CEL, Transmission, ETS, ABS, Airbag and other systems. There are also codes for other control units such as transmission, ABS, SRS, ESP, 4ETS, airbag, A/C. Mercedes-Benz can have up to 47 control units. You can NOT diagnose them with a simple OBD-2 scanner.
What does the p2048 code on an exhaust mean?
P2048 code definition The P2048 code is a generic powertrain code related to the exhaust system. In this case, it means that the reductant injector circuit located on bank 1 unit 1 of the exhaust has a low circuit. Codes related to the P2048 include:
What does stored code p2048 in PCM mean?
A stored code P2048 means that the powertrain control module (PCM) has detected insufficient voltage in the control circuit for the reductant injection valve for engine bank two and selective catalyst reduction (SCR) system one. Bank 1 refers to the bank of the engine that contains the number one cylinder.
What causes a p2048 reductant injection valve shorted circuit?
Causes for this code may include: Bad reductant injection valve Open or shorted circuits in the reductant injection valve control Insufficient DEF in the reservoir Bad SCR controller/PCM or programming error What are some P2048 troubleshooting steps?
