#254 of 353 Vehicle Skid Control and Vacuum Switching Valve by bws950 Aug 14, 2007 (8:23 am)
My wife and I recently bought a 2001 Avalon with 100k on it, and then drove it about 1800 miles on our honeymoon. Halfway through the trip, the check engine light came on, along with the VSC and VSC Off lights. We drove the rest of the way home without incident (though the brakes feel a little jittery occasionally, but that may just be normal). We bought the car from my inlaws and it hasn't had this problem before. I took it to an independent mechanic, and it failed the emissions test. He told me there was a problem with the Vacuum Switching Valve (about $200 to replace - maybe he was just replacing the cap?) and that fixing this could solve both the check engine light and the VSC issues. I know nothing about cars, but that seems a bit strange to me. Are the two related? What should I do?

#255 of 353 Oxygen sensors by obafunque Sep 04, 2007 (4:31 pm)
During 2005 I had engine lights on due to oxygen sensors bank 1 and bank 2. I replaced both and after awhile lights went off. Now, after two years, same problem, same codes P1135 and P1155............ is that a normal situation or something else is going up with the car? I have 118,000 miles an trying to keep the car in optimal conditions. Any suggestions? Fixing the car at the dealer cost > $600.00......please let me know.

Replying to: bws950 (Aug 14, 2007 8:23 am) You may have already found the answer??? However, we too have a 2001 XLS with 86k and exactly the same thing happened. Car continues to work normally and if you disconnect the battery cable for a few moments and reconnect, the lights will go away for a few days. Anyway, took the car to Toyota dealership. Diagnosis: For engine light and VSC light on-- Codes: P0440, P0441, P0446        EVAP codes, needs V S V. Replaced rear VSV part no 90910-12264 Valve, switching $73.70 cdn.        Metric 6-bolt 6mm 0.76cents        Metric 6-nut 0.44cents        Hose clamp HS32 0.99cents LABOUR $43.77 Total cost: $119.66   Trust this helps. Pretty sure it would probably cost $50 D.I Y.
#257 of 353 98 Avalon Engine stutter. Check Engine light by gloucas Oct 02, 2007 (10:27 am)
My 1998 Toyoto Avalon XLS with 91,000 miles recently started stuttering when I accelerate suddenly or accelerate when going uphill. Today I noticed it began to lose power when I was going up a hill then the check engine light came on. I parked the car and let the engine cool down for about 90 minutes. When I restarted the check engine light came back on and the loss of power was very noticeable.   Any ideas what this may be? (The problem seemed to start just after my 90,000 mile service a few weeks ago).
#258 of 353 Ignition Problems by pattyroy1 Oct 02, 2007 (2:11 pm)
My '98 Avalon has been having ignition problems lately. Every time I start the car the engine check, oil check, and battery check lights come on. However, I just replaced the oil (100 miles ago) and added new water. Plus, the car will make no sound as if it were about to start, only the three lights will appear, nothing else. Does anyone have an idea what might be causing this? Thanks.
#259 of 353 Toyota Avalon by retrojordan23 Dec 03, 2007 (12:27 pm)
I own a 1998 Toyota Avalon XLS and my check engine light recently went on. When accelerating, the car studders and shakes and takes a very long time to get up to the desired speed. A few times, the speed actually started to go down when I accelerated. It does run fine once it is up to higher speeds but the problem continues to occur in first and second gear mostly. If anyone has had similar problems with their toyota avalon or knows what to do to fix it, please let me know immediately. Replies to this message: brumor (Mar 09, 2008 8:58 am)
#260 of 353 Re: Strange noise when starting engine (sounds like a relay) [sofl06avalon] by brandt48 Dec 26, 2007 (1:20 pm)
Replying to: sofl06avalon (Jul 09, 2006 6:02 am) Hi,   I recently purchased a 2005 Ltd. and I performed the test as you described. It appears you are exactly right and the the steering locked with the noise even after waiting as much as a minute or two before opening the door. Now that I'm convinced, where do I go from here to have it corrected and did you have your's repaired?

Replying to: oldyotadriver (Mar 08, 2007 11:35 pm) Regarding the rattles you have noticed...check to see if the passenger seatbelt is twisted. Another person identified that as a source of rattles and I found it to be the case with my '05 Avalon. Just untwist and it quiets right down.
#262 of 353 Timing Belt? Chain? 2003 Avalon by melott Jan 01, 2008 (1:59 pm)
Replying to: footie (Nov 04, 2002 6:34 pm) I have a 2003 Avalon. The maintainence charts say nothing about belt replacement. Are there recommended time intervals for belt replacement (assuming it has a belt)? Mine is low mileage.
