2000 Toyota Sienna Problems

Check Engine Light Due to Failed Oxygen Sensor

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

Low Engine RPM or Stalling on Cold Start

The 1998-2003 Toyota Sienna 3.0L V6 may start and stall, or start and run at very low engine speeds when the engine is cold. 

The issue is a failed or dirty idle air control valve. This valve is mounted under the throttle body, and modulates airflow to the engine under certain conditions. When the valve becomes dirty, or when the valve fails, proper airflow to the engine is not achieved. This results in start and stall, and low RPM.  

To correct the issues, the idle air control valve will need to be tested, and cleaned or replaced. 

To help decrease the frequency of this issue, change the air filter no less than once per year. 

Rough Idle and Backfiring Engine with Check Engine Light

The 3.0L V6 engine used in the 1998-2003 Toyota Sienna has a known issue with the valves that if left unchecked, will cause burned valves and engine performance issues. 

The engine ‘breathes’ through valves that are pushed open by the camshaft, and closed by springs. When valves are closed, they seal against a valve seat. In this vehicle, the valve seat is too soft, so after the valve contacts it thousands of times, it becomes crushed. Once it is crushed, the valve can no longer make a proper seal, and the valves erode due to extreme temperature (burnt valve).

Symptoms related to this issue:

To repair the burnt valves, the cylinder head must be removed and rebuilt, which is a costly internal engine repair, however, this issue can be prevented through inspection and adjustment of valve clearances every 40,000 miles.

Had my Toyota since oct 99' first off the line. I changed brakes the first time at 125K Miles. I sent a letter to Toyota TWICE in concern about the brakes lasting so long, just lucky. I've change the timing belt twice, struts, rear shocks, various sensors and lights. Even though the bumpers suck. Nothing unusual at 244K owner miles from oct 99' to aug 2013' this is the best vehicle I've owned a...

Said it was the cleanest they had ever seen for the year. Okay, they don't deal with clean cars then. The first test drive the tire inflation light stayed on constant. The passenger seat belt light on/off/on. Higher speeds created a vibration ...

My first was a 90'. then a 93 twice and then a 97 and had a come back two or three times, another 93 and well all I can tell you is I really enjoyed them and only one or two of them had trans problems. My last was a 97 grand and could not get the trans r...
