Check Engine Plan
Turn the check-engine code you already have into severity, a plain-English cause, and a fix-or-mechanic plan. Enter the code plus your vehicle's year, make, model, and mileage; get back one report that tells you how serious it is, what's likely wrong, whether it's a DIY job — with parts, tools, steps, and difficulty — or one for the shop, with a script to use and a fair quote range.
One report, $7.99. A single one-time payment via Stripe Checkout. No subscription, no account, no hardware to buy.
Severity first. How urgent the code is — keep driving, fix it soon, or stop now — before anything else.
DIY or mechanic, called plainly. A clear verdict for your vehicle and mileage: a DIY fix plan with parts, tools, steps, and difficulty, or a mechanic script with a fair quote range so you walk in informed.
A private link you can keep. We email your report link after payment; share it only with people you trust, such as your mechanic.
Full refund, 7 days. Not useful? Email us within 7 days of purchase for a full refund, no questions asked.
Reports are generated with the help of a large language model and are informational, not professional mechanical advice. Quote ranges are estimates, not guarantees — always confirm the diagnosis with a qualified mechanic before authorizing repairs.
