2003 Toyota Avalon Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2003 Toyota Avalon

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

 

On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

Intermittent failure of a purge control valve in the evaporative emission system can cause the Check Engine Light to illuminate. A failed valve should be replaced to correct this problem.

The airbag control module can fail prematurely due to electrical noise beyond the tolerance it was designed for. As a result the front airbags, side airbags, and/or seatbelt pretensioners could deploy inadvertently while the vehicle is being operated, increasing the risk of personal injury and/or a crash. Dealers will replace the airbag control module and front and/or side impact sensors as required to correct this concern.

Toyota is recalling 2000–2004 Avalon models due to improper casting of the steering lock bar, which may cause the bar to crack or even break. If the bar breaks, the steering wheel will lock, causing the driver to lose control of the vehicle, increasing the risk of a crash. Dealers will replace the steering lock device free of charge.
