Car Computer Diagnostics at Telle Tire
Comprehensive Auto Diagnostic Services
Whether your check engine light is on or you want peace of mind before a long road trip, take it to Telle for diagnostics.
What is Car Computer Diagnostics?
Modern vehicles’ performance–from engine functions and transmission operations to exhaust systems and more–is continuously monitored by a series of microprocessors and sensors. These computerized systems communicate with the vehicle’s central module, storing “fault codes” whenever issues are detected, typically resulting in an illuminated check engine light. Through a car computer diagnostic test, experienced technicians retrieve these codes to identify and address issues efficiently.
Why You Need an Auto Diagnostic Check
Early Detection of Issues
Regular diagnostic testing is crucial for maintaining your vehicle’s health and longevity by detecting potential problems early. They also help ensure optimal performance, fuel efficiency, and overall safety, reducing the risk of an unexpected breakdown. A fault code may be thrown for various reasons, including:
- Faulty Oxygen Sensors
- Mass Airflow Sensor Problems
- Misfiring Cylinders
- Transmission Issues
- Catalytic Converter Failure
- Battery and Charging System Failures
- Fuel System Issues
- Exhaust System Problems
- Brake System Faults
- Cooling System Malfunctions
Taking your vehicle to the experienced technicians at Telle Tire can help get ahead of these issues to minimize impact and prevent more excessive wear.
Improved Vehicle Performance
An auto diagnostic check improves overall vehicle performance by ensuring all systems function correctly. Many common fault-code issues can lead to problems with fuel efficiency, emissions, engine performance, overheating, and more. Taking a proactive approach means you stay ahead of these potentially expensive repairs for a more efficient, smoother driving experience that extends the lifespan of your vehicle.

Computer Diagnostic FAQs
We know that auto repairs can raise a lot of questions. We’re here to help.
A standard car computer diagnostic usually takes around 30 minutes to an hour. However, if the issue is complex or intermittent, it may take longer to pinpoint the exact cause. At Telle Tire & Auto Centers, our technicians use advanced diagnostic tools to quickly and accurately identify problems—saving you time and helping prevent future issues.
Yes, you can use an OBD-II scanner to read basic trouble codes yourself—especially if your check engine light is on. However, these scanners often provide limited information and don’t always pinpoint the root of the problem. Our certified technicians at Telle Tire go beyond the codes to fully interpret what your vehicle’s systems are telling us and recommend the right fix.
Absolutely. Even if your check engine light isn’t on, your vehicle’s computer can store “pending” or historical codes that indicate potential issues. Plus, diagnostics can help uncover problems with other systems, like ABS or transmission performance. If something doesn’t feel right while driving, it’s a good idea to bring your car in for a professional evaluation.
A full car diagnostic includes scanning your vehicle’s onboard computer systems for trouble codes, checking real-time data from sensors, and reviewing system performance. At Telle Tire, we also perform a visual inspection under the hood and around key systems to make sure we’re getting a complete picture of your vehicle’s health.
Some of the most common check engine codes include:
- P0171/P0174: System too lean (air/fuel imbalance)
- P0300: Random/multiple cylinder misfire
- P0420: Catalyst system efficiency below threshold
- P0442: Small EVAP system leak (like a loose gas cap)
- P0128: Coolant temperature below thermostat regulating temp
These codes can point to anything from a minor sensor issue to a more serious engine problem. That’s why it’s best to have the issue professionally diagnosed and repaired.
