Evidence: Described by posterThe person describes what happened in words, without screenshots or video.
Outcome
The poster reads codes with a scanner, then runs them through Google, ChatGPT and Grok, asking for the most likely causes based on online forums and reviews, and works through each likely fix with YouTube. They say the top-ranked fix has been right each time, and that they've fixed check-engine lights on three vehicles this way in two months: a Toyota 4.7 and Ford 6.0 and 7.3 engines.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to. Goal: Rank the most likely causes of my car's trouble codes, based on what owners report in forums and reviews. Fill in before running: - Make, model, year and engine: [VEHICLE] - The codes from my scanner: [CODES] - Symptoms: [SYMPTOMS] Safety first: anything touching brakes, steering, airbags, fuel lines or lifting the car is a job for a qualified mechanic unless I confirm I have the tools and experience. Say so clearly. Rules: - Rank causes by how often owners report them for this engine. - For each, give a rough cost and difficulty. - Suggest what to search on YouTube for each fix. - Say which cause to rule out first because it's cheap or quick. - Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify. - If two codes are probably related, say which one to fix first. Output: A ranked list of causes with cost, difficulty and a search phrase for a how-to video. You'll know it worked when: the code clears and stays off after the fix. Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

SlashGear describes YouTuber Watch Wes Work asking ChatGPT about three codes (P0171, P0420, P1101) on a 2015 Chevrolet Trax. ChatGPT suggested checking for exhaust leaks, then inspecting the mass airflow sensor and air intake, and gave theoretically accurate test methods, but its normal airflow reading was vague. The YouTuber found vacuum leaks in a PCV hose and the valve cover and, asked whether ChatGPT diagnosed the issue, said it's a matter of perspective, but ultimately it did not; SlashGear says it lacked hands-on context for this model.

A driver replacing a sensor to clear a check engine light says Grok led them astray for 40 minutes; they had to use Google to find where the sensor was. Once they found it the job was easy, and the light went off. The poster's conclusion: AI is not good at fixing cars.

After a check-engine light on his pickup, a driver read one evaporative-system code and the sensor readings, then asked Gemini and ChatGPT what they meant. Gemini suggested replacing the sensor; ChatGPT said to clear the codes and see if they came back. He cleared them, and after a long trip the code hadn't returned, avoiding a costly, labour-heavy part replacement for now.
