What Does the P2041 Code Mean?

The reductant system uses a selective reduction catalyst to improve exhaust emissions and fuel efficiency by injecting a reductant into the exhaust system. The reductant also referred to as diesel exhaust fluid is a 32.5% solution of urea in deionized water. The reductant system reduces Nitrogen Oxides (NOx) present in the exhaust stream to nitrogen and water.
The Reductant Injection Air Pressure Sensor sends voltage reading information to the Powertrain Control Module (PCM). The PCM interprets these readings as pressure or exhaust gas temperature. The code is set when the voltage sent from the sensor to the PCM is out of factory specifications.
