How it works

Enter an OBD code (for example P0420) and the car make. See the available definition, its limits and what to check next. Manufacturer-specific codes can mean something different from generic ones.

  1. Enter the fault code.
  2. Choose the car make.
  3. Read the definition and recommended checks.

Frequently asked questions

What does the first letter mean?

P is powertrain, B body, C chassis and U the network between modules.

Can I repair the car from the code alone?

No. The code shows where the computer saw a problem, not which part failed. Follow the checks before replacing parts.
