P0200 OBD-II: Injector Circuit/Open
P0200 Severity
Should you fix P0200 yourself?
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.
What causes OBD-II fault code P0200?
The engine control module (PCM) has special transistors called "drivers" to turn the Fuel Injectors on and off in the Fuel Injection System. If the PCM cannot control the fuel injector, it will set code P0200.
