If your spark plugs or spark plug wires are bad or old, you will experience a noticeable poor performance and decreased power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more costly repairs.

  • One of the most common and frequent cause is that your Toyota Yaris gas cap is loose, broken or missing. The gas cap for your Toyota Yaris serves numerous purposes. It prevents hazardous gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a broken fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more costly. Luckily, to replace a gas cap isn't costly. If your check engine light turns on quickly after you put gas in your Toyota Yaris, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your Toyota Yaris has a vacuum leak. Every Toyota Yaris has a vacuum system that performs a wide variety of functions.
