What is the error code for cylinder 4 injector?
When the injector is switched off, the PCM expects to see a voltage close to battery voltage or “high”. If it doesn’t see what it expects to see, it detects a low or high voltage drop or resistance at injector 4, which activates the Error Code P0204.
What are the common causes of code p0304?
What are the common causes of code P0304 ? When you encounter a single cylinder misfire, the causes of systemic misfires such as: fuel pumps, timing problems, EGR valve leaks, or crankshaft position sensors are less likely. Individual spark plugs, fuel injectors and valves should be carefully examined for the cylinder.
What does a low voltage fuel injector code mean?
In a nutshell, this particular code indicates that the PCM is experiencing a low voltage situation involving the fuel injector for the number 1 cylinder in the firing order. Put simply, the fuel injector is malfunctioning and it could be due to a wide range of reasons.
What does trouble code p0204 mean on cylinder 4?
This code means the PCM (powertrain control module, also known as ECM or engine control module in other makes) detects a problem in the injector or its wiring, or in the injector circuit for cylinder 4. This code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II, or vehicles made in 1996 to present.
What does a faulty fuel injector code mean?
Some of them include: faulty fuel injector, loose or corroded fuel injector connector, dirty fuel injector supplying the number one cylinder, plugged fuel injector, and open or short in the fuel injector harness etc. You must be curious to understand what this particular code indicates.

What causes a fuel injector to stick on a car?
Problems. Rust can cause it to stick. If it can’t open, it can’t deliver fuel. Open Fuel Injector – A faulty spring or rust build up can cause a valve to stick in the open position. This will cause the injector to leak fuel. Leaky Fuel Injector – If a fuel injector overheats and fails, it will cause a leak.
