Affordable solutions:

Use OBD-II scanners available for Rs. 2,500–5,000

Brands: ELM327, Autel, Launch basic models

Apps like Torque Pro Android o r OBD Auto Doctor

Visit local workshops with scanner tools cost: Rs. 300–800 per scan

These tools can read error codes like P0171 lean mixture o r P0121 TPS fault without visiting a dealership.
