More Information

  • Will This Guide Help Me Clear Fault Codes?

    Being shown a fault code such as p0171 or p1351 is one thing, but knowing what it refers to and how expensive the fix may be is something else altogether.

    Haynes DIY helps you diagnose and clear these codes. After purchase, you can use the Fault Code Search to lookup and translate issues. For example, a P0171 error means 'System too lean' - affected components will also be shown, along with instructions and wiring diagrams on how to establish the likely cause of your problem.

    Please note: We recommend buying a fault code reader (also known as an OBDII) to use with your Haynes DIY Online Manual. They are readily available online and from automotive stores, and start from around $150.

  • Is This Different From a Printed Haynes Manual?

    Haynes DIY isn’t a printed Haynes manual, but it has plenty of other benefits!
