Engine Diagnostic Service

engine diagnosticEvery vehicle sold in the United States after 1996 is equipped with a computer that monitors and controls the various aspects of your vehicle including operating its engine. This computer is known as the On-Board Diagnostics-II or OBD-II. Mechanics use this computer to provide engine diagnostic for issues with your vehicle including determining why your check engine light came on. We do this by plugging in an OBD scanner into your car’s computer that reads it for errors. Once the OBD-II scanner completes engine diagnostic and generates a code indicating a malfunction, our mechanics can begin to make repairs.

If your check engine light is on, schedule an engine diagnostic and OBD2 scan in Springfield and West Springfield, MA with Spartan Auto Care by calling (413) 781-2480.

How Does an OBD-II & OBD-II Scanner Work?

Your vehicle’s on-board computer stores a fault code every time that it determines that something is not working properly. These fault codes can often trigger your check engine light and require engine diagnostic. Using an OBD-II scanner allows our mechanics to retrieve these fault codes to determine the exact nature of your vehicle’s issue. There are thousands of fault codes that can be triggered by your OBD-II. Once our ASE certified mechanics recover the fault code or DTC from the engine diagnostic, we match it to the corresponding issue and begin your repairs.

Reasons for Engine Diagnostic

Your OBD-II can require engine diagnostic for a substantial variety of reasons ranging from a loose gas cap to mistimed piston firing. This is because roughly 80% of all of the functions of car engines are controlled by an OBD-II.

Top 5 Engine DIagnostic Causes

  • Oxygen Sensor Failure: Oxygen sensors measure the amount of unburned oxygen in your vehicle’s exhaust. A worn sensor collects and provides inaccurate data, decreasing gas mileage.
  • Loose Gas Cap: When gas vapors escape, your vehicle’s fuel system becomes inefficient and triggers the check engine light.
  • Catalytic Converter: This device converts carbon monoxide into less harmful emissions. Normally, a failed catalytic converter is the result of another issue that has gone unresolved such as a broken oxygen sensor.
  • Mass Air Flow (MAF) Sensor: MAF sensors instruct your engine to increase or decrease the amount of gas depending on how much air is traveling through your engine. Typically, MAF sensor failure is the result of incorrect air filter installation.
  • Spark Plugs: Spark plugs inevitably wear out. Vehicles made prior to 1996 will need to have their spark plugs replaced every 25,000-30,000 miles. Vehicles made after 1996 will need their spark plugs changed roughly every 100,000 miles.
