2001 Toyota Sienna Problems

One or more oxygen sensors may fail resulting in illumination of the Check Engine Light.

The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.

The mass air flow sensor on higher mileage cars occasionally needs to be cleaned or replaced if sluggish acceleration is experienced or the Check Engine Light is illuminated with a mass air flow meter sensor fault code stored.

2001 Toyota Sienna Recalls

Toyota is recalling 1998–2010 Sienna models manufactured or registered in twenty-two Eastern and Midwestern states because of problems with the spare tire carrier and assembly cable due to road salt corrosion. This may cause the spare tire assembly cable to break and the spare tire to separate from the vehicle, increasing the risk of a crash. Toyota will notify owners via letter with instructions on how to remedy the problem. For a list of the affected states, call Toyota at 1-800-331-4331.

2001 Toyota Sienna Reviews

Most reliable vehicle that we have ever owned. Runs smooth and quiet. Very versatile carrying people and things. Have 84,000 miles at almost 8 years and replaced a single light bulb other than tires, brakes and a battery.

Best car I've ever owned. Just went over 200,000 miles last week. No problems other than standard maintenance. ...although I think the air compressor is starting to go out.

Just hit a deer 2 week...
