Code P3150 Description

The solenoid-controlled injection valve discharges a high-pressure spray into the combustion chamber. The solenoid-controlled injection valve is a retracting-plunger valve characterized by a high level of flexibility in its spray-propagation pattern (angle and shape). The discharge orifices form the high-precision injection pattern. This provides even and consistent propagation. The retracting-plunger solenoid-controlled injection valve continues to maintain stable propagation properties, even at the temperatures and pressure levels encountered within the combustion chamber. Fuel is injected into the combustion chambers under high pressure (between 50 and 200 bar) during the intake and compression strokes. During the warm-up phase yet another, a minute quantity of fuel is injected to assist the catalytic converter to reach its effective operating temperature more quickly (catalytic converter heating). During cold starting, the fuel is sprayed during the compression stroke in multiple pulses. This strategy provides reliable cold-starts along with substantive improvements in the areas of pollutant emissions and fuel consumption.
The Digital Motor Electronics (DME) diagnosis monitors the activation of the high voltage side of the fuel injector. The Diagnostic Trouble Code (DTC) is detected when there is a short circuit to B+.
