Not all car problems require you to run to the nearest repair shop to get them fixed. Most times, taking some simple steps to car problems diagnosis is all it takes for you to identify the issue at hand and take a jab at fixing it yourself. Read on to learn more.
Your Car Won’t Start
If you turn the key in the ignition and the engine doesn't start but you hear a single click or rapid clicking, your battery may be weak or dead, or your battery terminals may be corroded. Here are two simple ways to get it moving again.
- Warm the battery: The chemical reaction that produces the energy in car batteries is slowed down in the wintertime. The output of the battery can be increased if the battery can be warmed up. Simply turning the key to start several times, providing a 5-minute break in between, will warm up the battery.
- Use the shoe trick: If the previous attempt to start it fails,
Take off your shoe, then tap the heel on each battery terminal.
Afterward, try starting the car. If it starts, clean the battery terminals right after you get home.
Fix Slow Acceleration
The Mass Airflow Sensor (MAF) is used by your car's computer to gauge the volume, mass, and temperature of air entering your engine. After that, it determines how much fuel should be added. The computer receives distorted readings and calculates the amount of fuel to add incorrectly if the sensing components inside the MAF are dirty, which leads to performance issues.
Purchase a can of MAF Sensor Cleaner from any auto parts store to clean your MAF sensor. By loosening the worm drive clamps using a screwdriver or socket, the sensor can be taken out of the air duct. Then, point the spray cleaner directly at the MAF housing's sensing components. If you touch the sensing components with your fingers, a rag, or a brush, they will break. So, you need to soak them instead. Reinstall the MAF after allowing the solvent to dry.
If a dirty sensor was the root of your acceleration issue, cleaning it should restore your performance. If not, have a professional examine it.
Diagnosing a “Check Engine” Light
Your car's computer has detected an issue with the engine or transmission and stored a trouble code in its memory. When you see the relevant signs. "Check Engine", "Service Engine Soon", or "Reduced Power" lights or warning messages on the dash indicate this error. The culprit in most cases is a faulty sensor, which you can probably replace yourself. First, though, it'll be useful to seek information that is relevant to your specific car model. A Ford car manual, for instance, will likely provide you with all you need to fix the problem you’re having with your F-250.
Repair a Dim Headlight
The majority of DIYers believe that a bad connection on the power side of the circuit is what causes a dim headlight.
Although it's possible, corrosion on the ground connection is typically to blame for the headlight's dimness. You must first inspect the electrical connector for corrosion before cleaning the ground connection to solve this issue.
Use an electrical contact cleaner and a small wire brush to clean up any corrosion you find. If the connector has melted instead, head to an auto parts store to buy a new pigtail headlight connector.
If your headlights are bright upon reconnecting the part, it's done. If not, you’ll need a professional diagnosis.
Diagnosing a car problem yourself and following a car manual to fix it can save you thousands of dollars in professional repairs that are sometimes unnecessary. Be sure to refer to this guide the next time you face one of these common car issues!
