The P0149 diagnostic trouble code (DTC<\/a>)<\/strong> indicates that the Engine Control Unit (ECU)<\/strong> has detected a fuel timing<\/a> error<\/strong>.<\/p>\n

This code is most commonly associated with diesel engines<\/strong>, where precise control of fuel injection timing<\/a> is critical for efficient combustion and emissions<\/a> control.<\/p>\n

If the ECU detects that the fuel injection timing<\/a> is outside the expected range<\/a><\/strong>, it stores the P0149 code<\/strong> and turns on the Check Engine<\/a> Light<\/strong>.<\/p>\n

How Fuel Injection Timing Works<\/h2>\n

Modern diesel engines rely on precise injection timing<\/a> to control combustion.<\/p>\n

The system uses several components:<\/p>\n
