2003 Toyota Avalon Problems

Exhaust & Emissions -- Verified

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.

Electrical & Lights -- Verified

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.

Exhaust & Emissions -- Verified

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.

Drive Train -- Verified

At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

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.
