Troubleshooting a P0017 code on a 2015 Ford Fiesta, suspecting VVT solenoids are bad but unable to confirm because bench test shows no movement, unsure if both solenoids failed simultaneously.

No way to reliably verify if VVT solenoids are faulty without specialized diagnostic tools or access to professional scan data; generic test methods (bench test with power) are inconclusive.

Workarounds Described

bench tests solenoid by applying power and watching for movement

Implied Software Gaps

A diagnostic tool that can test VVT solenoids in-vehicle with definitive pass/fail results

App Concept

SolenoidScan Pro

A portable diagnostic tool and app that tests VVT solenoids and other engine actuators directly on the vehicle without removal. It provides pass/fail results, waveform analysis, and comparison to known good values for common models. Eliminates guesswork and saves hours of disassembly.

Key Features

Plug-and-play test with vehicle-specific adapters
Real-time waveform display and analysis
Automated comparison to OEM specs for common vehicles
Step-by-step guided diagnostics with trouble code integration

Target Users: DIY vehicle owners and independent auto repair shops working on Ford, GM, Toyota, and other common brands with VVT systems.

Revenue Model: $199 one-time hardware purchase plus $9.99/mo cloud subscription for waveform library updates and advanced diagnostics.
