What does it mean if your car has no code?
Perhaps the thought of a no-code driveability problem signals a difficult day ahead. But today you’re up for a good challenge and you can’t get to the gravy work until this job is done.
What happens when the catalytic converter is misfired?
This is primarily due to the misfire count not exceeding the limit. But there’s another way Ford protects the catalytic converter during misfire conditions. The misfire section of the OBD II document explains that if the PCM determines a cylinder is misfiring, the fuel injector can be turned off to protect the catalyst from damage.
What does the misfire section of the OBD II mean?
The misfire section of the OBD II document provides a key piece of information that will help reduce the amount of time it takes for Profile Correction Learn to complete.
When to turn off the fuel injector in OBD II?
The misfire section of the OBD II document explains that if the PCM determines a cylinder is misfiring, the fuel injector can be turned off to protect the catalyst from damage. Once the fuel injector is turned off, the cylinder is now basically an air pump, which reduces the potential for catalyst failure.
Why does my car have an error code for fuel injector?
The experts believe that this code primarily shows up because of the production of less power in the number two cylinder, stating the lack of fuel to the number two cylinder as the most likely cause. It is also possible for the vehicle to face this issue because of a variety of diesel injector problems.
What is the fuel system on demand code?
The vehicle’s PID data was watched very closely as it warmed up. After closed loop operation was obtained, it was noted that both upstream oxygen sensors went well below 0.5 volts and remained there. The fuel system status then went to open loop fault. A review of scan tool data shows a code P1131 and P1151 stored as “On Demand Codes.”
What is the diagnostic code for a fuel pump?
It is also possible for this problem to arise because of a dirty or clogged fuel filter or a defective fuel pump. P0253 is widely known as the diagnostic trouble code for “Injection Pump Fuel Metering Control A Low (Cam/Rotor/Injector.” This trouble code can be caused due to multiple reasons.
What does p0301 mean on a spark plug?
P0301 simply means that cylinder #1 is not firing properly. Spark plug, wire, coil pack, fuel injector, vacuum leak, mechanical problem, etc, all can cause this code. Forget about the fault codes and just go about diagnosing it as you would have before OBD2.
