P2344 Severity
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
If the fuel injector does not allow sufficient fuel into the cylinder, it will cause the cylinder to run lean. This will create an engine knock. The injectors have a calibration number on the side of them that needs to be entered into the engine computer (PCM) anytime the injector is replaced. If the number is not entered into the PCM, code P2344 will be stored.
