What is a P2048 code?
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.
What is a reductant pump?
The Reductant Pump transfers the DEF (Diesel Exhaust Fluid) from the tank to the DEF Injector. If the Reductant Pump fails to perform as requested by the engine computer (PCM), code P208A will be stored.
Where is reductant pump located?
The electrically operated DEF (emissions reductant) pump, which is located within the DEF reservoir, is designed to deliver pressurized reductant to the reductant injector located upstream of the Selective Catalytic Reduction Catalyst.
Where is the reductant level sensor?
Reductant level sensor 3 is located at less than half range of the DEF tank level. The scan tool will display Active when the level sensors are in contact with reductant and Inactive when not in contact with reductant. An integrated temperature sensor monitors reductant temperature.
What does the error code p0128 mean?
Code P0128 indicates that the engine coolant hasn’t gotten hot enough in the appropriate timeframe. The Engine Control Module (ECM) is responsible for monitoring the ambient temperature and determining if it is in line with manufacturer specifications.
What does the trouble code p0125 mean on a car?
For most vehicles, trouble code P0125 is related to this issue as well. Your thermostat is an essential component for regulating coolant temperature and checking for more serious issues with your engine. However, a damaged thermostat won’t typically cause any performance issues. So, what does the code P0128 mean?
How do you diagnose a GM p0128 coolant malfunction?
With a GM P0128 code, the first step is to get it properly diagnosed to figure out what is causing the malfunction in the coolant temperature circuit. Using the live data function of the FIXD sensor and app allows you to read and analyze engine temperatures to properly diagnose a P0128 code.
What are the diagnostic requirements for the p2050 code?
You will need access to a diagnostic scanner, a digital volt/ohmmeter (DVOM), and a source of vehicle specific diagnostic information to diagnose a code P2050.
