PTX™ is AutoSonix’s signal convergence index a standardised 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 — 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 behaviour aligns with expected operating patterns at the point of intake.
Rather than relying on one data source, PTX™ combines two independent signals OBD data and AutoSonix acoustic AI and 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, system status
Structured mechanical sound — engine acoustics converted into repeatable data.
A consistent intake signal showing how the 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 standardised 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.
