Application Description

Piston: Your Onboard Car Diagnostic Tool

Turn your smartphone into a powerful car diagnostic tool with Piston! Access real-time data and troubleshoot engine issues easily.

Is your Check Engine Light (MIL) on? Piston reads Diagnostic Trouble Codes (DTCs) and Freeze Frame data, providing crucial information to pinpoint and resolve the problem. You'll need a Bluetooth or WiFi ELM327 adapter to connect to your vehicle's OBD2 port; Piston provides clear connection instructions.

Key Piston Features:

Read and clear OBD2 standard DTCs.
Analyze Freeze Frame data (sensor readings at malfunction detection).
Monitor real-time sensor data.
Check emission control device status (Readiness Monitors).
Save DTC history locally or in the cloud (cloud requires login).
View sensor data charts.
Export sensor data to a file.
Retrieve your car's VIN.
Examine ECU details (OBD protocol, PID count).

Note: Premium features require a one-time in-app purchase; no subscriptions!

Compatibility:

Piston works with ELM327 adapters and supports OBD-II/EOBD standards. OBD2 is mandated in the USA for vehicles from 1996 onwards. EOBD requirements in the EU began in 2001 (petrol) and 2004 (diesel). Australia and New Zealand adopted OBD2 in 2006 (petrol) and 2007 (diesel).

Important: Piston only accesses data your vehicle provides via the OBD2 standard.
