Describe your symptoms
Noise, smell, warning light, or how the car behaves — plain language is enough.
- 2
Add codes or vehicle details
Paste an OBD-II code and your make, model, year and engine for more specific guidance.
- 3
Get guided next checks
A structured list of likely causes and the tests worth running before buying parts.
Built for mechanics, DIYers, and everyday drivers.
Whether you're a professional technician, a DIY enthusiast, or just trying to understand what your car is telling you, WrenchPulse guides you step by step in plain language.
Professional mechanics
A fast second opinion and an organized record per vehicle, so nothing gets lost between jobs.
DIY enthusiasts
Ranked likely causes and the checks worth doing first, before you order parts.
