P2048
Reductant Injection Valve Circuit Low Bank 1 Unit 1
DTC P2048, sometimes indicated as P204800 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing reductant injection valve circuit low bank 1 unit 1.
The reductant injection valve circuit low code is set when the reductant injection valve signal is less than the reductant injection valve threshold.
There are several possible causes for this code, including a defective reductant injection valve, a low reductant injection valve signal, a defective reductant injection pump, a low reductant injection pump signal, or a defective powertrain control module.
If you have access to a scan tool, checking the reductant injection pump signal and the reductant injection valve signal can help you determine the root cause of the code. If either of those signals are low, then the problem is most likely with the pump or valve. If neither of those signals are low, then the problem is likely with the powertrain control module.
If you don't have access to a scan tool, then you'll need to take the vehicle to a mechanic to have it diagnosed.
