Why Choose Us for Engine Diagnostics in East Tyler
Advanced Diagnostics
We use professional-grade diagnostic scanners and equipment to accurately identify engine problems, not guesswork.
Fast Diagnosis
Our experienced technicians quickly pinpoint issues, saving you time and preventing unnecessary part replacement.
Clear Explanations
We explain what we find in plain language and provide honest recommendations for repairs—no technical jargon.
Modern engines are complex computer-controlled systems with dozens of sensors, actuators, and control modules working together. When something goes wrong, symptoms can be confusing—check engine lights, poor performance, strange noises, or reduced fuel economy. Accurate diagnosis is essential to fix the real problem efficiently and cost-effectively, rather than replacing parts based on guesswork.
At Josh Hawkins Automotive, we invest in professional diagnostic equipment and ongoing training to properly diagnose engine problems on all makes and models. Located near Whitehouse, we serve East Tyler with expert engine diagnostics that identify root causes quickly. Whether your check engine light is on, your engine is running rough, or you're experiencing performance problems, we'll determine exactly what's wrong and provide clear repair recommendations.
Common Engine Diagnostics Issues We Fix
Check Engine Light
The check engine light indicates your engine computer detected a problem. It could be something minor like a loose gas cap or serious like catalytic converter failure. We scan for trouble codes, interpret the data, perform tests to confirm the diagnosis, and explain exactly what's wrong and what repairs are needed.
Rough Idling or Misfires
Rough idling, shaking, or misfires indicate combustion problems. Causes include worn spark plugs, bad ignition coils, clogged fuel injectors, vacuum leaks, or compression loss. We diagnose the specific cylinder and component causing misfires using diagnostic data and specialized tests, then repair or replace the faulty parts.
Poor Fuel Economy
Sudden decreases in gas mileage indicate engine inefficiency. Common causes include faulty oxygen sensors, mass airflow sensor problems, thermostat failures, or fuel delivery issues. We analyze fuel trim data, test sensors, and diagnose the root cause to restore optimal fuel economy and save you money at the pump.
Loss of Power
Sluggish acceleration or lack of power can result from numerous issues including restricted exhaust (clogged catalytic converter), fuel delivery problems, ignition system weakness, or turbocharger failures. We perform power balance tests, check fuel pressure, test ignition output, and inspect exhaust restriction to identify the cause.
Overheating
Engine overheating can cause catastrophic damage if not addressed immediately. We diagnose cooling system problems using pressure tests, scan data for temperature sensor accuracy, check thermostat operation, inspect water pump function, and identify leaks or airflow restrictions. Quick diagnosis prevents expensive engine damage.
Strange Engine Noises
Knocking, ticking, rattling, or grinding noises indicate mechanical problems. We identify noise sources through systematic testing—checking valve train components, bearing wear, timing chain condition, and accessory drive systems. Accurate diagnosis determines whether repairs are minor adjustments or major overhauls.
Our Diagnostic Approach
Computer Diagnostics
We connect professional scan tools to your vehicle's onboard computer to retrieve diagnostic trouble codes (DTCs), monitor live sensor data, check fuel trim, review freeze frame data, and test component operation. This gives us a detailed picture of what your engine computer is detecting and how systems are performing.
Physical Testing
We perform hands-on tests to confirm diagnoses including compression testing, leak-down testing, fuel pressure measurement, ignition system testing, vacuum testing, and visual inspection of components. These tests verify electronic diagnoses and identify mechanical problems that sensors might not detect.
Test Drive Evaluation
Many engine problems only appear under specific conditions—acceleration, cruising, hot or cold engine. We test drive your vehicle while monitoring diagnostic data in real-time to observe problems as they occur. This helps diagnose intermittent issues that might not appear during static testing.
Component Testing
When diagnostic codes point to specific components, we test those parts to verify they're actually faulty before recommending replacement. This includes testing sensors, actuators, switches, and modules using multimeters, oscilloscopes, and specialized testers. We only replace parts we've confirmed are defective.

FAQs About Engine Diagnostics in East Tyler
How much does engine diagnostics cost?
Basic diagnostic services typically cost $75-$150, depending on complexity. This fee covers computer scanning, initial testing, and diagnosis of the problem. If you proceed with repairs at our shop, we often apply the diagnostic fee toward the repair cost. Complex diagnoses requiring extensive testing may cost more, but we'll provide an estimate upfront.
Can't I just buy a code reader and diagnose it myself?
Inexpensive code readers only retrieve basic trouble codes—they don't interpret what those codes mean or identify root causes. Professional diagnostics involves analyzing live data, performing specialized tests, and using experience to determine the actual problem. A code saying "oxygen sensor low" might mean a bad sensor, or it might mean an exhaust leak, fuel delivery problem, or catalytic converter issue.
How long does engine diagnostics take?
Basic diagnostics typically take 30 minutes to 1 hour. Complex problems requiring extensive testing, test drives under specific conditions, or diagnosis of intermittent issues may take 2-3 hours. We'll give you a time estimate based on your symptoms. Accurate diagnosis takes time but prevents expensive misdiagnosis and unnecessary part replacement.
Will diagnostic services fix my problem?
Diagnostics identifies the problem—repairs fix it. Once we diagnose the issue, we'll provide a clear repair estimate. Some problems are simple fixes completed during diagnosis (like tightening a loose gas cap), but most require parts and labor. Understanding what's wrong before starting repairs prevents wasted money on unnecessary parts.
Can you diagnose problems without a check engine light?
Absolutely. Many engine problems don't trigger check engine lights—noises, vibrations, performance issues, or fluid leaks. We use computer diagnostics when applicable, but also rely on systematic testing, visual inspection, and diagnostic experience to identify problems that don't set codes. Our comprehensive approach diagnoses issues regardless of whether warning lights are illuminated.
