PTX™ is AutoSonix’s signal convergence index, a standardized intake baseline that tells you whether independent mechanical signals agree or conflict, instantly, for every vehicle.
PTX™
100-85
"Everything makes sense for this vehicle"
✓All signals align. No elevated risk.
PTX™
84-60
“Normal wear. Nothing unusual.”
✓Most signals align. Minor deviations.
PTX™
59-40
“Something is a little off. Take a closer look.”
⚠Some signals conflicting or incomplete
PTX™
39-0
"Multiple things don't line up"
✗Mechanical evaluation strongly advised
PTX™ stands for Powertrain Signal Index. It is a single, objective score that reflects how closely observed powertrain behavior aligns with expected operating patterns at the point of intake.
Rather than relying on one data source, PTX™ combines independent signals. OBD data, contextual information and AutoSonix acoustic capture. PTX™ measures whether they align or conflict. The result is a band, not a verdict. A starting point, not a final answer.
This gives every team member, regardless of technical background, a consistent, repeatable baseline to support faster, smarter decisions.
No single signal determines PTX™ . OBD has existed for decades. AutoSonix's acoustic signal is new. Together they create something neither can produce alone.
On-board diagnostics. Fault codes, sensor data, and system status.
Structured mechanical acoustics converted into repeatable data.
A consistent intake signal showing how multiple inputs relate.
PTX™ integrates into your existing intake workflow without disrupting it. From auction lanes to dealership trade-ins to warranty underwriting. One consistent signal layer. Everywhere.
PTX™ provides a standardized mechanical signal that integrates into your existing workflow from intake to disposition. Whether you’re managing auctions, servicing fleets, evaluating trade-ins, or underwriting warranties.
PTX™ is integrated across AutoSonix's platform solutions delivering the same signal layer to every type of automotive business.
