P0274 code definition

P0274 is a trouble code that denotes an above average draw of current from the number five cylinder’s fuel injector.

What the P0274 code means

If you see this code, it means your vehicle’s engine cylinder number five is operating below a satisfactory level or, in some cases, not at all, because of a problem related to the circuit itself. The problem can go on to affect the oxygen sensor, spark plug, catalytic converter and other important components.

What causes the P0274 code?

There can be a number of reasons you’re seeing a P0274. It could even be a symptom of a much greater problem. However, the most common causes for this code are:

What are the symptoms of the P0274 code?

The symptoms you experience will depend on a number of factors. However, there are a handful that are common enough that you should know to look out for them. Reduced suffering fuel economy is definitely one. A lack of power when you accelerate is another. When you’re idling, if the engine is running rough, this would be another symptom.

How does a mechanic diagnose the P0274 code?

Most mechanics will begin by checking the fuel injector as corrosion is often causing the problem. A loose fuel injector may be the issue to address too because it causes excessive resistance which increases the voltage needed to operate. They’ll check the fuel injector’s electrical connector for pins that are bent or pushed out. Repairing this problem may be all it takes to make the code disappear without further work being necessary. Sometimes, the mechanic will find that all that is necessary is simply cleaning the injector. However, sometimes, it will just need to be replaced. After doing everything to revive the injector, the mechanic will use their scanner to erase the code and then restart the engine. If 0274 returns, then it’s time to replace the injector.

Common mistakes when diagnosing the P0274 code

As we just covered, sometimes the solution is as easy as simply cleaning the fuel injector. Some mechanics will skip this step, causing unnecessary replacements. Another common mistake occurs after repairs are done. The damage that caused the P0274 code may have been the fuel you were using. E10 anhydrous ethanol content in fuel causes water vapor that reduces the lubrication fuel injectors need to run properly. Therefore, after repairs, don’t make the mistake of going back to this fuel type or you’ll need another trip to the mechanic in no time.

Note: this problem is especially pronounced in smaller vehicles. The smaller engines are affected to a much larger degree by the water vapor.

How serious is the P0274 code?

In extreme cases, your car may backfire or you’ll otherwise experience engine problems. Also, when your fuel economy begins lacking, you’ll have to spend more money at the pump. Although your safety won’t necessarily be at risk, these are two good reasons to get your vehicle inspected by a professional right away.

What repairs can fix the P0274 code?

Fortunately, cleaning the fuel injector may be all the repairs you need. Otherwise:

Additional comments for consideration regarding the P0274 code

If left alone, this problem can quickly evolve into something worse by the way it affects other elements like the oxygen sensor or spark plug.

Chevrolet Equinox - Check Engine Light is on - Chicago, Illinois
Chuy came to service and look over a vehicle I purchased 12 days ago. He was extremely professional and told me off the top that I paid way to much money on a truck that is basically a lemon. He told me to take it back and get my money and the God I was able to do just that without issue. The truck has way to many issues going on and should not be sold to anyone for driving. The wait for my mechanic Chuy was well worth it and I will continue to use this company for my vehicles.
