Advanced Vehicle Diagnostics in Pataskala, OH

Precision Tools, Trusted Answers

At Tanzillo Automotive, we understand how frustrating it is when your vehicle isn’t running right, especially when you don’t know why. That’s where our advanced diagnostic service comes in. Using industry-leading tools and years of experience, we get to the root of the problem fast and fix it correctly the first time.

Whether it’s a check engine light, odd noises, or your vehicle just feels “off,” you can trust our team to diagnose the issue with accuracy and honesty.

Why Accurate Diagnostics Matter

If a shop misdiagnoses your issue, the result is usually wasted time, wasted money, and a vehicle that still isn’t fixed. We believe the job isn’t just to fix the symptom, it’s to find and correct the actual cause.

That’s what our advanced diagnostics process is built for.

Whether it’s electrical faults, engine misfires, transmission shifting problems, or intermittent issues that only show up under certain conditions, our tools and expertise allow us to get it right the first time.

How We Diagnose the Toughest Vehicle Issues

Modern vehicles are complex. One small issue in the wrong place can trigger multiple symptoms and even multiple warning lights. That’s why we don’t rely on guesswork.

Our technicians use top-of-the-line Autel scanners, oscilloscopes, and manufacturer-level data to perform in-depth system scans and pinpoint exactly what’s going wrong. Our team brings years of advanced training to every diagnosis, including college education, trade school expertise, and manufacturer-specific training courses. With two Ford ASSET graduates and multiple Ford Senior Master Technicians on staff, we combine cutting-edge diagnostic tools with real-world experience to solve even the most complex issues.

We perform diagnostic services on all makes and models, including:

Domestic vehicles

When to Schedule a Diagnostic Service

If your vehicle is showing any of these signs, it’s best to schedule a professional diagnostic inspection. Catching issues early can prevent bigger, more expensive repairs down the road.

Check Engine or Warning Lights

When the check engine light or other dashboard indicators (like ABS, airbag, or traction control) come on, it’s your vehicle’s way of signaling a problem, even if it seems to drive normally. These lights can represent anything from a minor sensor issue to a serious engine or emissions problem, and a scan with our advanced tools will reveal exactly what’s going on.

Sluggish Acceleration or Rough Idle

If your vehicle feels slow to respond when you hit the gas or the engine vibrates or lurches at idle, you may have an issue with the ignition system, clogged fuel injectors, or dirty sensors. These symptoms often start small but can lead to reduced performance and fuel efficiency if not addressed.

Engine Misfires or Hesitation

Sudden jerks, engine “hiccups,” or a noticeable loss of power while driving often indicate misfires in the combustion process. These can be caused by worn spark plugs, failing coils, or timing issues, all of which our diagnostic tools can pinpoint accurately.

Hard Starting or Random Stalling

If your engine takes longer than usual to crank or shuts off while driving or at stoplights, it could be a sign of a failing starter, a weak fuel pump, or a faulty sensor. These issues can be intermittent and frustrating, which is why proper diagnostics are so important.

Transmission Shifting Issues

If your vehicle hesitates before shifting, shifts too hard, or feels like it’s slipping between gears, the issue could lie in the transmission, fluid condition, or the control module. Diagnosing these problems early can help you avoid more extensive (and expensive) transmission repairs.

Unusual Noises or Smells

If you hear clunking, whining, grinding, or hissing sounds or notice burning smells or strong fuel odors, your vehicle is likely experiencing a mechanical or electrical issue. These warning signs often indicate failing components or fluid leaks, and should be checked out immediately.

Frequently Asked Questions

What does a vehicle diagnostic test include?

A diagnostic test involves scanning the vehicle’s onboard computer for error codes, evaluating sensor data, and testing electrical and mechanical components to identify the root cause of performance issues or warning lights. Advanced diagnostics may also include using tools like oscilloscopes and manufacturer-specific software for deeper analysis.

How long does a diagnostic service take?

Most diagnostic tests take between 1 to 2 hours. The duration depends on the complexity of the problem; intermittent issues or electrical faults can take longer to accurately identify. It could take many hours to identify some issues.

Do some vehicles need special diagnostic equipment?

Absolutely. Diesel trucks, late-model vehicles, and those with advanced electrical systems often need more than a basic code scan. At Tanzillo Automotive, we use factory-level tools and in-depth testing methods to pinpoint the problem, saving you time, money, and unnecessary repairs.

What are common signs that a diagnostic test is needed?

Common signs include the check engine light coming on, unusual noises, poor fuel economy, rough idling, hard starting, or shifting issues. Diagnostics should be scheduled as soon as symptoms appear to avoid further damage or costly repairs.
