✓ Manufacturer-specific information for P1 codes

📱 100% OFFLINE — SIN REGISTRATION
DtcGran works completely offline. The database is included in the app—no account, registration, or subscription required. Check codes anywhere, even without mobile coverage in the workshop or on the road.

🔍 TWO SEARCH MODES

By exact code: type P0171, C0035, B0001, U0100, DF011...
By text: search for "catalytic converter," "ABS," "injector," "turbo," "EGR"...

🏭 MANUFACTURER SELECTOR FOR P1 CODES
P1 codes are manufacturer-specific—the same number can mean different things in a VW than in a Ford or Renault. DtcGran automatically detects P1 codes with multiple interpretations and displays a manufacturer selector so you can choose yours and get the exact information.

📋 COPY TO CLIPBOARD
Copy the complete code information with one tap — description, system, severity, causes, and solution — to share with your mechanic or save for later.

🔌 WHAT IS OBD2?

OBD2 (On-Board Diagnostics) is the standard self-diagnostic system found in all vehicles manufactured in the USA since 1996 and in Europe since 2001. When the Check Engine light illuminates, the ECU stores a DTC code that identifies the problem. DtcGran helps you understand that code without needing a workshop.

⚠️ IMPORTANT NOTICE
DtcGran is a reference and informational tool. P1 codes are manufacturer-specific and may vary depending on the model and year. This information does not replace professional diagnostics. Always consult a qualified technician.
