The Top Eight Check Engine Light Issues

According to CarMD’s 2013 Vehicle Health Index, auto repair costs are up 10 percent this year. Putting off car repairs is a bad idea because unresolved issues often lead to more expensive repairs. If the check engine light comes on in your car, take your car to a qualified mechanic immediately. Here are eight of the most common reasons for the check engine light to activate.

1. Malfunction of the oxygen sensor

Oxygen sensors keep the engine running at peak efficiency and manage emissions. O2 sensors monitor gases leaving the engine. Engines need the correct fuel and air ratios to operate most efficiently. Breakdowns can reduce fuel consumption by up to 40 percent. It also negatively affects engine performance.

2. Problems with the ignition coil

The ignition coils draw electricity from the battery and light the spark plugs. Without the coils and spark plugs working properly, the electrical current that runs your car’s engine is cut off. All parts in a car’s electrical system take a lot of wear and tear from the current passing through them.

3. Spark plugs and spark plug wires

Along with ignition coils, spark plugs and wires are critical components of a vehicle’s electrical system. Symptoms of plug and wire problems include rough engine idling, engine misfires or pings, erratic engine power including power losses and power surges. When engines fail, fuel consumption drops. Ignoring spark plug and wire problems can permanently damage a car’s catalytic converter, leading to very expensive repairs.

4. Malfunction of the mass air flow sensor

The mass air flow sensor or MAF measures the air coming into the engine and calculates how much fuel should be added to the mixture. This data goes to the engine control unit (ECU). Without the correct information from the MAF, the ECU cannot properly balance or deliver the right amount of fuel to your engine. The result is very poor engine performance and a 10 to 25 percent reduction in fuel efficiency. Replace this critical component immediately if it begins to fail.

5. Defective vacuum hose or fume emission control system

A car’s evaporative emission control (EVAP) system prevents the release of gasoline vapors from the fuel system and gas tank into the air. Leaky vacuum hoses and vents, faulty valves and faulty gas caps all contribute to EVAP system problems.

6. Exhaust gas recirculation valve and openings are dirty

The Exhaust Gas Recirculation (EGR) system controls your car’s emissions and helps cars run more efficiently. Rough idling, engine hesitation, and misfires can indicate an EGR problem. Deteriorated performance and fuel economy are often the result of EGR problems. Often the components of the EGR system are dirty or clogged.

7. Catalyst failures

Catalytic converters are often the most expensive mechanical repairs on vehicles. As part of the exhaust system, it converts dangerous chemicals in car exhaust into less harmful compounds that it releases into the air. The catalytic converter should last the entire life of the car. Most problems with catalytic converters come from underlying problems such as those caused by bad spark plugs or ignition coil problems.

8. Empty battery and problems with the charging system

Most cars have computer systems that monitor the voltage in the electrical and battery systems. Computers activate the check engine light when something goes wrong with the car’s charging system. High temperatures in the engine compartment contribute to the rapid aging of the battery.
