1999 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.

Sludge can build up in the engine because Toyota did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.

1999 Toyota Sienna Questions

Engine doesn't sound any different, nothing different about my van, just the light came on.
Oil was very very low, added oil, cleaned air filter, but light is still on? Can I reset the light by pulling the fuse out and putting it back in?

The EVAP code 440 was returned. Did a smoke test and found a plastic valve on top of the gas tank is leaking. Very hard to get to and because of the age and rust this is going to be a bigger job than it should. Cannister and other valves OK. Anyone else encounter this?

1999 Toyota Sienna Reviews

Had to have A/c system recharged at 70,000 miles, had problems with A/C again at 129,000. Still having problems at 188,000. Also have a slight oil leak now. Other than that its been a great running car. Would buy another one. Probably after 200,000 miles.

We bought ours new in '99, and it handled beautifully then. Now, not too bad. brakes are good, heating and AC good. No problems at all with exhaust and emissions. 2 coils went bad, caused hesitation on cold days, and it took a very long time (over a year) to diagnose by 2 different mechanics. The drivers side window motor needed replaced: about $300. The tailgate door opener/handle cost 30...
