Automotive RepairDiagnostics & Troubleshooting4HighOwner$ implied
A car owner cannot resolve a persistent P2097 diagnostic trouble code (post-catalyst fuel trim too rich) despite replacing multiple expensive parts, and fuel trims read lean contradicting the rich code.
Standard OBD2 codes and DIY part replacement do not help when the code contradicts sensor readings and the root cause (e.g., fuel injector, ECU issue, or vacuum leak) is not obvious. No accessible guided diagnostic tool that interprets conflicting data.

Workarounds Described
- scans codes with OBD2 scanner
- replaces parts guessing which is faulty (catalytic converter, O2 sensors, etc.)
- checks fuel trims manually by driving different conditions
Implied Software Gaps
- A diagnostic app that interprets OBD2 codes in context of live sensor data and suggests probable root causes
App Concept
CodeClarity Diagnostic
A mobile app that interprets OBD2 trouble codes alongside live sensor data (fuel trims, oxygen sensor voltages) to pinpoint the root cause. Unlike generic code readers, it correlates codes with trim values and suggests likely fixes for that specific vehicle model, reducing guesswork and wasted parts.
Key Features
- Vehicle-specific diagnostic logic that explains conflicting codes and sensor readings
- Guided step-by-step troubleshooting based on live data
- Database of known fixes for common trouble codes per make/model/year
- Interactive report to share with mechanics
Target Users: DIY car owners and shade-tree mechanics who want to fix persistent check engine lights without expensive trial-and-error part swaps.
Revenue Model: $4.99 per diagnostic report or $9.99/month subscription for unlimited scans
