1998 Toyota Avalon Problems

Ignition Coil May Fail After 100,000 Miles

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.

Automatic Transmission May Not Shift Correctly at High Mileages

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.

Replace EVAP Canister to Correct EVAP System Problems

The Evaporative system may have problems with the vapor canister releasing charcoal pellets that plug the vent valve. Typically a Code P0441, P0442 and P0446 will be set. The key code is the P0446 which is a vent valve electrical failure. The proper repair is to replace the entire canister with all the valves as a unit. This is located on top of the fuel tank and is expensive. Our Technicians tell us that for awhile Toyota was covering these problems, but this may have changed. It would not hurt to call the dealer if this problem occurs to see if Toyota is still helping with these repairs.

1998 Toyota Avalon Reviews

My car is making a knocking noise increasing in loudness. If it is not the motor, what else could it be? My car has slightly over 230,000 miles.
This car now has 104k miles and it runs beautifully. All I had to do is replace the rotors, brakes, tires, which are all due to the high mileage. The mechanic tells me it will run for some time.
