Engine Diagnostics

 

 

In order to meet Federal Exhaust Emission and Fuel Economy regulations, today's vehicles are equipped with highly sophisticated electronic engine control systems. These systems do not require periodic adjustments. The only services required on a scheduled basis are spark plug and filter replacement. Tune-ups, as we knew them, are no longer necessary.

Engine Control Computer

The computer receives information from a network of sensors and switches that convert engine operating conditions into electrical signals. Based on the information and instructions stored in the computer program, commands are then sent to three primary systems:

  • Ignition SystemYeck's auto repair in Bellevue Nebraska can service all of your automotive engine needs

  • Fuel System

  • Emission Control System

The sensors that monitor one or more of these systems include:

  • 1. Mass Airflow Sensor

  • 2. Throttle Position Sensor

  • 3. Manifold Absolute Pressure Sensor

  • 4. Coolant Temperature Sensor

  • 5. Exhaust Oxygen Sensor

  • 6. Crankshaft Position Sensor

  • 7. Camshaft Position Sensor

 

Check Engine Light

When your check engine light comes on, you may be torn between utter panic and just wanting to ignore it and hope it goes away. That’s perfectly understandable. That same check engine light could come on for anything from a serious engine or transmission problem all the way down to a loose gas cap.


There’s a very common misconception that the trouble codes stored in your engine computer when your check engine light comes on will specifically identify a problem. It’s really more like pointing to the symptoms of a problem.
Call Yeck’s Tire & Auto Repair at 402.293.1200 for help with your check engine light.


 Think of taking your temperature. Say it’s 101. Your heat sensor – the thermometer – tells you that your temperature is out of the normal range. But it doesn’t tell you why you have a fever. Is it the flu or a sinus infection? You need more information; more tests.


For any given trouble code, there could be a number of causes. So your trained technician takes the trouble code as a starting point and begins a diagnostic process to determine the cause of the problem. And some problems take longer to solve than others.


When your engine management system logs a problem and illuminates the check engine light, your Bellevue service technician at Yeck’s Tire & Auto Repair will plug in a scanner, download the trouble codes and go to work tracing the cause of the problem.


That’s just the first step. That’s when your technician’s training, equipment, databases and skill get put to work diagnosing the problem and fixing it.


If your check engine light is flashing it means that the problem could lead to serious damage. You should get to your local Bellevue NE service center as soon as possible to get the problem solved. If it’s on but not flashing, you have some time to get in at your convenience.


 


 

MAF Sensor


Air and fuel are mixed together to be burned in your engine. You request how much of each you need by how hard you press on the accelerator, by going up or down a hill or by how much you are carrying in your vehicle as your drive around Bellevue. Based on how much air you need – and how much is available – your engine management computer sends the needed amount of fuel to your engine. But what if the computer is getting the wrong information about how much air is coming into your engine? Well, it would send get the wrong amount of fuel and your engine wouldn't perform the way you need it to.

The Mass Air Flow (MAF) sensor measures the volume, temperature and density of the air coming into your engine. With that information, the computer calculates how much oxygen is available to burn and adjusts the amount of fuel it sends. A dirty or damaged MAF sensor will provide inaccurate air flow readings, which can lead to drivability problems, damage your catalytic converter, set off the Check Engine light and may even prevent the engine from running.

The good news is that Bellevue drivers can prevent most MAF sensor contamination. As air comes into your engine, it first passes through the engine air filter. Dust, road grime, pollen and other contaminants are captured in the filter. When the engine air filter becomes very dirty and clogged, some of the contaminants pass through the filter and hit the MAF sensor. That is how the sensor can become so dirty or damaged that it cannot accurately measure the air flow. So replacing your engine air filter as recommended will extend the life of your MAF sensor and help keep your engine running smoothly.

Now if your MAF sensor is contaminated, it may be possible to clean it with an air induction cleaning service at Yeck's Tire & Auto in Bellevue. This service also cleans your throttle body and other fuel system components. In those circumstances where the MAF sensor has been damaged, it will need to be replaced.

Approximately 12,000 gallons of air pass through your engine air filter for every gallon of fuel you burn (45,000 liters of air for every 4 liters of fuel). That's a lot of air to clean – and your air filter must be up to the job. Replacing this relatively inexpensive part will not only prevent dirt from getting into your engine, it will help keep your MAF sensor functioning properly. Your technician can easily inspect your engine air filter to see if it should be replaced. A caution: low-line air filters may actually contribute to MAF sensor failure as filter material can come loose and contaminate the sensitive sensor elements. A good quality engine air filter is your engine's first line of defense.

When your Yeck's Tire & Auto Service Advisor recommends you replace your engine air filter, you now know how much is riding on that simple part.
