What does the engine code P0200 mean?
Definition: Injector circuit malfunction
The P0200 engine code indicates that there’s a problem with your injector circuit. The electrical loop determines and controls how much fuel should be pumped into the engine at any given time.
How much will it cost to fix?
It’ll cost about one hour of labor to diagnose the exact problem with your injector circuit. The exact price can vary depending on which mechanic you use. Repair costs vary based on the vehicle make and model, but will usually fall between $75 to $150.
What can cause the P0200 engine code?
The P0200 code suggests that there’s a malfunction within the injector circuit. That usually happens when the injector circuit is open or shorted.
A car’s injector circuit is a relatively complicated system that links the engine to your vehicle’s control module. Basically, it figures out how much fuel should be sent to the engine, and then regulates the process in real-time. Malfunctions usually happen when the harness—a tiny wiring system—either breaks or short-circuits.
But it’s not the only reason for a malfunction. It can also occur when your vehicle has a:
- Fuel injector circuit poor electrical connection
- Faultyfuel injector
- Faulty Engine Control Module (ECM)
Common symptoms of the P0200 engine code
Outside of a telltale
check engine warning light
, there aren’t too many obvious symptoms of a P0200 problem. However, some general issues might point towards a P0200 issue, such as: In some cars, the engine won’t start if there’s a problem with the wiring. Although it may point to a bigger issue, your ignition not working could also be a sign of a P0200 code.
How serious is the P0200 engine code?
The good news is that the P0200 engine code isn’t terribly dangerous. Car technology is pretty advanced these days, so minor faults can often be masked and won’t necessarily put your life at risk when you get behind the wheel.
However, it’s not a good idea to be driving a car with an injector circuit malfunction. You might find that your car stalls or
engine misfires
, which can put you in some uncomfortable situations. It’s also possible that a faulty injector circuit could lead to more serious problems and put unnecessary stress on your car’s control module. Can I fix the P0200 engine code myself?
An injector circuit is difficult to fix and tends to be a job for a professional. You can help expedite the process by inspecting your injector circuit. If there are any bent wires or eroded connector pins, you might be able to better explain the problem to a mechanic.
Still, even if you feel comfortable identifying a P0200 code, it’s important that you don’t try to fix it yourself. If you’re not a properly trained mechanic, you run the risk of doing some serious damage to your engine—and racking up even higher bills. Though it may be a pain to pay up for some repairs, it’s better to spend $100 for some wiring changes than thousands for a broken engine.
