#3540 of 3629 Service engine P1135
Apr 27, 2010 (2:24 pm)
I am surprised this topic is not on this board. Unless I missed it, this problem seems to be a common problem with these cars and other Toyotas. I have received a 'check engine light' on my dash. I took the 2002 Avalon XLS to Auto Zone and was told the code is P1135. The printout also staes Air/Fuel sensor heater circuit response (bank 1/sensor 1). Other possible causes are #1 'open or short circuit condition' and possiblity #2 'poor electrical connection'.
My guess is that I need to replace the O2 sensor on the exhaust manifold next to the firewall. I will also check to see if the wire connector has come loose. I took it to my mechanic, and he reset the code. He did not have time to repair or research the problem, but he said it is possible the fuel intake experienced a slight trash issue. Anyway, he cleared the code, and by the time I got a block away, the light came back on.
I am curious if anyone else has had this issue. I would love to just be able to repair the problem, but I am a little leery about replacing the one O2 sensor and the problem is elsewhere.

Hopefully you are in luck. I have over $550 invested to fix it and they didn't, including toyota and outside garage. At lunch , I lucked out and business owner had had the problem with his truck. His service garage mechanic told him to reset the computer. Wow! I have done that too many times on this thing on the modem, so I shut off the power by disconnecting the battery terminals for a long delay. reconnect had effect of resetting the car computer. problem solved. He said you might have to do it again.I believe him as this has happened on this computer before! You get to reset the clock area but what a pleasure! Cost, zero! Good luck. Incidentally, garages both said no problems as indicated on dash warning lights.

I just purchased a 1998 Avalon XLS. It had only 87,900 miles. I took it to Meineke for pre-purchase inspection (PPI). The car is SOLID!!! It drives like magic. I noticed though that when braking from high speed (60mph and above) the steering kinda wiggle. What do you guys think the issue is?
I will greatly appreciate comments.

Most likely warped front brake rotors and worn front brake pads... common on this first series Avalon. Front rotors were a weak point in an otherwise great car, had a '99 XL that went 90k and was near perfect... Enjoy the car..

I agree. We installed ceramic brake pads on our 03 and love the sporty feel. Love em.
#3545 of 3629 How urgent is it to change the camshaft drivebelt?
May 20, 2010 (3:44 am)
Our 2003 XLS has passed 90K. The maintenance schedule calls for the drive belt to be replaced, which is labor-intensive and therefore expensive. It is also recommended that the water pump be changed, since the same disassembly is necessary anyway.
Have owners experienced problems from not changing the belt, or at least delaying it for 25K miles?

I presume you are referring to the Timing Belt change here.
I experienced the same dilemma when my 2000 XLS reached 90K and I referred it to my trusted mechanic to help me arrive at a decision . However, it was his opinion that the car could easily go another 10 or 20 K miles based on his experience of working with similar cars where the timing belt was almost new even when it was replaced at 120K miles.
My car has crossed 107K now without replacement and touchwood there are no issues till now.
He also informed me that the Avalons have a non-interference engines - what that means is that the timing belts cause very little damage even if they break in operation.
Hope this helps

IMO if you are planning on keeping the car for a good bit longer (either miles or time) just go ahead and do it. If you do it now and drive the even for a another 100K you won't have to do it again. Its just piece of mind. OTOH if you are planning on dumping it in a year, then you will probably be safe and let the next owner worry about it.

Key words: non-interference engines
Don't gamble with an interference engine.
We are also pushing 90k on our 03, but we travel to Arizona. Would hate to snap it enroute. On the other hand, ours is in a nice garage most of the time and not out in a hot parking lot or -20 below. Pampered little thing in that regard, but I have heard a rumor that it may run at 90-100 mph on some open stretches in the SW. I may try to sneak one more trip in.
The other question is, how long do we keep it. With the suspension upgrade, we love the way this car drives, yet the value will now drop off a cliff, so to keep it means to run it til it drops. Here again. those trips must be considered. On the positive side though, I have the potential to drop 5-6k in value. Guess what the hit would be with a new/newer car. Not to mention the higher license, insurance depreciation etc. I keep trying out new models of various brands but fortunately, we still prefer to drive the Avalon - mostly due to the suspension upgrade, KYB GR2 struts and Energy sway bar bushings. Lucky duckies. Makes the choice much easier.
The new BMW 5 series in on the radar after it depreciates a few years. Would like to drive the new LaCrosse, but will depreciation still be an issue? The new Av is too much of a barge for me. Now if they would come out with an Avalon Sport by getting rid of those seldom used (Never for us) adjustable rear seats, and cut out that much space, then put our suspension under it with more aggressive body kit, they would be back in the game for us and have another new product with almost no development cost. Ya hearing me Toyota? What do the rest of you think? Of course, those most interested are probably not in this forum. Another reason to do it - another pool of prospective buyers that would not normally buy a Toyota.
OK, that's enough food for thought to chew on.
But wait - there's more. Look what I just found on a new owner review of the 2011 AV.
Love the car but would like to see a sport package as an available option for the Limited. Sportier suspension, better bolstered front seats & more road feel in the steering would be nice."
Could use a little of the Buick Lacrosse 'ambient' lighting to add a little 'pizazz' to a bland interior lighting scheme"

They tried a "Touring" edition for a few years after the intro of the 05. Obviously sales were weak because they dropped it. I test drove it, it was just a little firmer than an XLS/Limited. Think the difference between a regular Camry and an SE.
