Car Acting Up? Here’s What We Find Most Often

If you’ve noticed any of the following issues, our team at Cain and Sons’ Automotive is ready to run a thorough car diagnostic test to find out what’s going on:

Check Engine or Service Engine Soon Light

We scan and investigate why your light is on, whether it’s emissions, sensors, or a misfire, so we fix the issue, not just clear the code.

Electrical Failures

From dead batteries and sensor faults to short circuits, we test and trace your vehicle’s electrical system to restore full function.

Stalling, Misfiring, or Poor Fuel Economy

We diagnose ignition, fuel, or airflow issues causing hesitation, rough running, or increased fuel use.

Transmission, Fuel System, or Emissions Codes

We interpret fault codes from major systems and test components to confirm what needs attention.

ABS, Traction Control, or TPMS Warnings

We test wheel speed sensors, tire pressure systems, and brake electronics to keep your safety systems working right.

Drivability Problems

If your car shakes, idles roughly, or lacks power, we analyze live engine data to pinpoint the cause.

ADAS Issues After Repairs

Using the Autel ADAS IA900, we recalibrate features like lane assist and adaptive cruise after suspension or windshield work.

HVAC Problems

Whether it’s a weak blower, uneven heating, or warm A/C, we diagnose controls, motors, and refrigerant levels.

Pre-Inspection or Emissions Check Readiness

We clear unresolved codes and ensure your systems are ready to pass Pennsylvania state inspection or emissions testing.

We also help you prepare for state inspections and emissions testing by identifying and clearing up any underlying issues.

Smart Solutions Start with the Right Diagnosis

Check Engine Light Diagnostics

Our technicians use advanced scanners to perform an engine light scan, pulling fault codes and interpreting them accurately. We don’t stop there; we also perform live data analysis and hands-on testing to confirm the issue before recommending a fix.

Electrical Diagnostics

Whether it’s a power loss, intermittent warning light, or non-working accessories, we perform detailed electrical diagnostics using load testing, circuit tracing, and sensor monitoring to locate the exact issue.

ADAS Calibration & System Reset

Modern vehicles require advanced recalibration after certain repairs. Using the Autel IA900, we perform ADAS system resets and alignment to restore safety features like lane-keep assist, adaptive cruise control, and forward collision warnings.

Computerized Car Diagnostics

We perform diagnostic checks using factory-level software and scan tools, accessing data from your engine, transmission, brakes, and more to identify hidden problems early.
