Engine Management

The engine management system supplies a mixture of air and gasoline to the engine. A properly functioning engine management system reduces harmful fuel vapors and exhaust pollutants from the vehicle engine. The fuel and engine management system consists of eleven components, many of which require regular maintenance.


  • Mechanical Fuel Pump

    Function - transfers fuel from the gas tank to the carburetor.

    Signs of Wear - poor engine performance, trouble starting car, power loss while driving, problems accelerating.


  • Carburetor

    Function - delivers fuel into the engine's cylinders.

    Signs of Wear - engine wont start, rough-running engine, car is stalling, poor gas mileage.


  • Fuel Sender Unit

    Function - monitors fuel levels on transmits the information to the fuel gauge.

    Signs of Wear - inaccurate car fuel gauge reading.


  • Fuel Injector

    Function - sprays fuel into the engine's intake manifold or cylinders.

    Signs of Wear - poor engine performance, problems accelerating, dirty emissions air.


  • Mass Air Flow Sensor

    Function - measures the amount of air entering the engine to determine the most efficient air/fuel mixture for achieving clean burns.

    Signs of Wear - engine is stalling, poor engine performance, check engine light is on.

  • Throttle Position Sensor

    Function - electronically informs the PCM of the throttle's angle. The PCM uses this input to regulate the fuel and ignition system.

    Signs of Wear - check engine light is on, poor engine performance.

  • Idle Air Control/Linear Flow Valve

    Function - controls the amount of air that bypasses the throttle plate in order to regulate idel engine speed.

    Signs of Wear - high rpm at idle, engine stalling.

  • Fuel Pressure Regulator

    Function - controls the fuel pressure going to the fuel injectors.

    Signs of Wear - engine is knocking, engine lacks power, engine is smoking, increased exhaust emissions, poor gas mileage.

  • Modular Fuel Pump

    Function - located inside the fuel tank, the fuel pump delivers fuel from the tank to the fuel injectors or carburetor while the sender monitors fuel levels and transmits the information to the fuel gauge.

    Signs of Wear - engine wont start, problems accelerating, irregular power loss, inaccurate car fuel gauge reading.

  • Strainer

    Function - prevents larger contaminants inside the fuel tank from entering the fuel line.

    Signs of Wear - problems accelerating, low power.

  • In-Line Fuel Pump

    Function - located in the fuel line, an in-line fuel pump transfers fuel from from the fuel tank to the fuel injectors or carburetor.

    Signs of Wear - hard to start engine, slow acceleration, irregular power loss, engine is loud.


Service and Maintenance

Preventive maintenance can save you money at the gas pump. For instance, an engine requiring a tune-up could be wasting 15% or more of its fuel. To avoid such insufficiencies, bring in your vehicle if:

Your check engine light is on
Your engine stalls, hesitates, or idles improperly.
Your exhaust expels excessive smoke
You hear abnormal engine noise
You notice fuel odor

Unecessary fuel costs are the result of a poorly maintained fuel and engine management system. With a little preventive maintenance you can extend your vehicle life, increase vehicle saftey, and lower your fuel costs. Bring your vehicle into Wheatland Auto for a free inspection.
