No one likes to start up their vehicle only to be met with a “check engine” light, but unfortunately, it’s bound to happen to anyone sooner or later during their time as a vehicle owner. Generally, the check engine light is a good signal as to the development of a problem that’s still in its manageable stages—and as any driver knows, ignoring this warning generally leads to a much bigger problem down the line, sooner rather than later.
What exactly the issue is with your diesel vehicle might remain a mystery until you have it inspected by a professional, however. Take a look at some of the more common diesel engine repairs in Fredericktown, OH that you might find yourself faced with when you bring your auto in for service to remedy a check engine light:
- Your diesel’s internal computer might be reporting power issues, which are usually the result of a loose throttle linkage or a dirty fuel filter. Leaking gaskets might also signal low power issues. Either way, if your vehicle is reporting low power output, your check engine light is going to alert you to the problem. Bear in mind, however, that sometimes a power issue may cause your engine light to click on and off when you start your vehicle or drive it—this is generally the result of variable power readings.
- Glow plugs have their own light on your dash, making it easy to see when you’ve got a problem that specifically relates to these all-too-important components of your engine. Without properly functioning glow plugs, you’re going to have a hard time even starting your auto!
- An appropriate fuel-to-air ratio is important to keep a diesel vehicle’s engine in tip-top shape—if it leans to one side or another, more air or more fuel, the engine itself could suffer the consequences. Soot buildups can occur when there’s not enough air mixed in with the fuel, while fuel economy may suffer if there’s too much air. When your vehicle senses an imbalance that it’s not able to fix, you can be certain that your check engine light is going to click on.
- Does your diesel idle low, lack power when you hit the gas or have trouble getting up to speed? If so, you might be looking at a faulty fuel injector. Unfortunately, your check engine light might not always click on for this issue, however it’s one that you’re going to notice pretty immediately if it’s present.
- Air intake is a powerfully driving force of your diesel—so if your air intake is blocked, hindered or malfunctioning in any way, you’re going to see that check engine light flash on very quickly, alerting you to the need for diesel engine repairs in Fredericktown, OH.
These are just some of the more common problems that you’re likely to encounter as a diesel vehicle owner. Pay attention to your check engine light, your vehicle’s behavior and your regular service demands and you’ll be more equipped to catch and remedy these problems before they truly sideline your trusty auto.
