ECU Error Clear - OBD2 Catalyst Tool

Automatic P0420/P0430 Code Fix. Smart Safety for recurring Check Engine Light.
AUTOMATIC CATALYTIC CONVERTER ERROR FIX

Tired of the constant Check Engine light caused by recurring P0420/P0430 codes? ECU Error Clear is the first application designed for fully automatic, hands-free clearing of catalytic converter efficiency codes.

Designed primarily for gasoline engines with catalytic converters, it provides a reliable and safe solution to the most common non-critical catalyst efficiency codes. It is specifically optimized for gasoline engines with LPG conversion and vehicles that experience frequent, non-critical catalyst errors.

EXCLUSIVE BENEFITS

  • No Ads, No Distractions: Designed to run silently in the background without draining your battery or data with annoying advertisements.
  • Set and Forget: Once configured, the app handles everything automatically.

SPECIFIC FEATURES

  • Automatic Clearing: Works fully in the background - no manual intervention needed.
  • Specific Codes: Targets P0420 and P0430 catalytic converter efficiency codes ONLY.
  • Intelligent Safety: Only clears P0420/P0430 when no other codes are present.
  • LPG Optimized: Advanced optimization logic included for gasoline engines with LPG conversions.

ADVANCED SAFETY SYSTEM

Unlike generic code readers, our intelligent safety system strictly follows a "no other errors, no action" principle:

  1. Scans for ALL diagnostic trouble codes (DTCs) before any action is taken.
  2. Automatically TERMINATES clearing if any codes other than P0420/P0430 are detected.
  3. Guarantees no clearing of critical safety codes (brakes, engine management, airbags, etc.).
  4. Operation is BLOCKED unless ONLY P0420/P0430 codes are present.

TECHNICAL SPECIFICATIONS

  • Compatibility: Designed for Gasoline Engines with catalytic converters (Optimization for LPG conversions included).
  • Adapter: Requires a high-quality ELM327 Bluetooth OBD2 adapter.
    • Recommended: Bluetooth 4.0 / BLE adapters for best connection stability and auto-sleep functionality.
    • Supported: Standard Bluetooth OBD2 adapters (ELM327 v1.5 with PIC18F25K80 chip is highly recommended for stability).
  • Codes: P0420, P0430 (catalyst efficiency only).
  • Operation: Full background automation.
  • Internet: Not required for diagnostics (License check only).
  • Android: 8.0+ (Oreo and newer).

SMART LOGGING SYSTEM

  • Complete history of all cleared P0420/P0430 codes with timestamps.
  • Configurable checking intervals (set your preferred frequency).
  • Detailed diagnostic session records.
  • View connection status and ECU responses in real-time.

HOW IT WORKS

  1. Connect your ELM327 Bluetooth OBD2 adapter once.
  2. Set your preferred checking interval (e.g., check every 5 minutes).
  3. App operates fully automated in the background.
    • If ONLY P0420/P0430 codes are present → Automatic clearing is performed.
    • If ANY other codes are present → Safety lock is immediately engaged, and NO action is taken.
  4. All actions are logged locally on the device.
IMPORTANT SAFETY NOTES:
  • This app is for NON-CRITICAL catalytic converter codes ONLY.
  • Will NOT clear any other error codes for safety reasons.
  • Does NOT fix mechanical issues or replace faulty components.
  • Always consult a professional mechanic for serious vehicle issues.
