P2664 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.
Newer vehicles use variable valve technology to allow for greater airflow through the engine at higher RPMs. This allows for better performance over a wider range. Some manufacturers are moving to a variable valve lift system that allows the valve to open wider. Internal to the variable lift rocker arm assembly are position sensors so the engine computer (PCM) can monitor what the assembly is doing. If the solenoid inside the assembly fails, code P2664 is set.
