Toyota - Sienna :: 2002 - Wobbles When Engine Is Under Load
Jun 3, 2011
2002 Toyota Sienna wobbles when engine under load and is more noticeable at certain speeds (like around 40 mph). The wobble is lateral in the body of the car and the steering wheel IS NOT vibrating.AutoMD web site suggests it may be the motor mounts. I did their diagnostic suggestion of putting the car in gear with the emergency brake on and foot on brake .. and revving the engine and letting up. I didn't notice a "knock" when the torque was released on the engine.My local mechanic is stymied ... says he checked the motor mounts, and front end mechanics and they are OK ...

Ok, here is what happens to my car:
The engine wobbles when idling or at very low speed - some times the engine shuts down in stop and go traffic (very dangerous). Doesn't pick up speed when i try to accelerate from a stop position - the engine revs up and then the car lurches forward (suddenly) as the transmission seems to engage. The same happen when i slow down to almost very low speed and then tries to speed up. I also hear a kind of thud (transmission most probably).
The CEL is ON and some time blinks.
My OBD is showing the following codes: P0171 P0172 P1150 P0300 P0302 P0304 and P0306

My Toyota Sienna 2002 van has been stalling when I stop off and on for about 2 weeks. Most times it starts up again and continues to run. I can go days and it doesn't happen then yesterday it happened 7 times in the course of 10 minutes. I've had it connected to a computer diagnostic system three times, couldn't find any error messages.

When it rains, it pours. My 2002 Sienna had a burned out headlight bulb the other day.
So, why am I even mentioning it? Buy a new 9003 bulb, open the hood, unplug the socket; pull off the rubber cover, twist the clip and take out the bad buld, and reverse it to put in the new one.
No one in town had a 9003. They did have 9004, but some on-line research said some bulbs have very precise placement for the filaments. While I am not sure 9004 is different wiring from 9003, why bother?
So, I dug in the box of used parts, found an old bulb I swapped out probably over 100,000 miles ago, grabbed some pipe cleaners and rubbing alcohol, and cleaned that old bulb and put it in. Works fine.

Coming home from a road trip we stopped for gas not 5 minutes later the check engine light started flashing. The car was fine as long as you were puching on the gas but as soon as you slowed to a stop it would either die or shudder until I gave it some more gas. Being stupid I figured that I could probably get it home since It was only 25 miles of freeway driving and I wouldn't have to stop until I got near my home. I took it to a mechanic the next day and they said that it was my timing belt.
The next day I get a call from them telling me my timing belt is fine but they discovered that a valve adjuster shim is missing on cylinder 6 and the adjuster cup is jammed down as well as a crack in the locating pin hole so that the pin is moving causing the cam to shift in relation to the cam gear. They suggested I rebuild or replace the cylinder heads and may need to replace the engine. What this could be?

Tonight our 2002 Toyota Sienna (automatic transmission) was in drive, but stopped (foot on brake) during a traffic jam. Traffic picked up and the driver moved his foot from brake to gas. The car went into reverse at a high speed. The brake did not work. The driver quickly changed gears to park.
1. What is (are) the problems resulting in this situation?
2. Has additional damage been done by switching into park?
3. Is it safe to drive to the repair shop?

I have a 2002 Toyota sienna XLE, 95k miles. A few weeks ago I replaced the battery with a DieHard. Immediately after this, the right sliding door stopped working. A few days later the left side stopped working. Neither sliding door works in the manual mode, child proof feature is disabled. Fuses are good. Both doors click when any associated switch is activated but don't open. It was suggested by an owner of an older Sienna that the auto door computer needed resetting. Worth a try. His procedure involved disconnecting the negative side of the battery, waiting 3-5 minutes, reconnecting battery, use the key fob remote to open a door and then close it using the fob. Wait 10 seconds open and close same as before, doing this a total of 3 times. It didn't work, door clicks won't open. Tried again same results. This makes sense and my thinking goes that perhaps the sequence is different for a newer model.

we have a 2002 Toyota Sienna Van; recently, there has been a smell like turpentine coming from the front passenger seat. We have tried spraying large amounts of the freeze on it to no avail.

I have had that car, the best one I have ever owned, since shortly after Nine-One-One, a date some of you may remember.
I never open any door but the driver's door with the key. Several months ago, for some reason it occurred to me to try and see if they worked.
Nope, both the rear hatch and passenger's door lock would not open with the key. I assumed that the mechanism corroded up over lack of use over the years.
I thought, Well, crud. But, since I haven't used those door locks in over 12 years, I can probably get by.
I thought I had lost the spare car key when I was in Texas in December. To my surprise, I saw it on the key rack in the kitchen here in rural Mexico. I took it out to the car to check it out, and it opens all the doors.
I compared the keys, and one of the 'vanes' on the key I use all the time is a very tiny bit smaller than on the spare key. My guess is either that key never opened those two doors and I never noticed it. Or, it has worn over 12 years.
So, I guess when I get back to the States, I will have a copy made of the spare key. I am also going to post this on Sienna Chat for obvious reasons.

Having been on a long road trip, I noticed that every time I switch off the engine, there is a grinding noise coming from the engine. Took the van in to Toyota for a regular service, they could not find anything wrong. I then took it to an alignment place having replaced all four tires. They heard the noise straight away and think it is a worn bearing in the cooling fan in the alternator. 2007 Toyota Sienna LE FWD... The car only has 22,956 miles on it.

My check engine light won't stay off. My mechanic keeps replacing things. He says its got to be the exhaust system. I was wondering if its something electrical or within the car's computer system. First time he replaced one of the catalytic converters. The light went off then reappeared several days later. He replaced the oxygen sensor. Light off again then back on 2 days later. Then he replaced the other catalytic converter. (I was told there are 3 of them). Once again the engine light went off but reappeared 2 days later.

200 Toy Sienna-- Had a oil leak, got it fixed. Drove 15-20 miles and Engine dies on me. Tried to restart, ignition is fine, engine does not catch on. Got it towed to shed, left overnight. Mechanic explains that car has to relearn throttle - memory got reset etc. Car drives fine now. Mechanic says, it did not start the first few times, then all he did was turn on the key and step on the Gas!! Is that right? Or did he forget to to do something? Who's memory is not working?

I have a 2000 Sienna van. My husband took it a shop for an oil change and now, the next day, there's an oil smell in the engine and it seems to be running hot. Here's the catch: it has a different engine from when I took it in last year to the same shop and they did an oil change and then the engine started smelling of oil, it ran hot, and after a few months the engine died (they told me checking the oil smell could wait and we were broke). I had to have the engine replaced. I would never have taken the van back to that shop! But now it's been there and I'm panicked! What should I do?

I own a 1999 Toyota sienna that has 112,000 miles. For the past few months there has been a whirring noise that seems to be coming from the center engine compartment. It started quietly and now has increased in volume. It reminds me of a speedometer cable that is beginning to fail. I have taken it to my trusted mechanic for a diagnosis and he thought it was metal on metal noise from the transmission. I have owned cars for 40 plus years and have'nt heard of this type of tranny noise. What could be causing this? It makes this noise under power and when I release the accelerator the noise almost disappears. Also there is a clunking noise coming from the passenger front wheel after releasing the brake pedal when I come to a stop. I have replaced the strut,ball joint,and lower control arm bushing trying to remedy this. I cannot find anything else that is loose.

I have a wobble in steering at 55 mph and have gone thru 2 sets of tires. After 1st set i changed front struts, no luck . When i rotate tires from rear to front it goes away for 6 months and tires start to wear wavy and wobble starts.

I have a 2000 Toyota Sienna that has had a check engine light for a while. The light would come at times, and go away at others, with prolonged intervals (days, weeks, months) with or without the light.
Suddenly it started losing power, especially on hills (even a small hill). The codes I read are (I include code interpretations from internet search):
P0300: Random or multiple misfire.
P0301: Cylinder 1 misfire.
P0304: Cylinder 4 misfire.
P1130: Air fuel sensor
P1150: I have not found a problem definition for this code.
Might these codes be indicative of a particular problem, or is each problem more likely a problem with its own cause?

The car is a manual transmission 2005 Toyota Corolla with around 90,000 miles. I'm not the only owner. The car was bought used. It appears that the car was in a front end accident that doesn't appear in a carfax report. This can be identified by the poor clearcoat paint job on the hood flaking off and the absence of the air conditioner, as well as some rather pathetic body, work with noticeable bends and a few missing screws. Most of which I consider cosmetic and irrelivant to the car's operations.
The tires are bald and the car has had an alignment about 2 years ago after I replaced the struts. I wasn't notified of any bad ball joints, but that doesn't mean thats out of the question. The car has a bit of a shake at high speeds. Sometimes the shaking is violent enough to reduce speed. I noticed that more often the shake is really bad above 60 and quite scary above 70. This isn't always the case. Sometimes the shake isn't as noticable by comparison.
At low speeds the car seems to have a wobble or repeatative hop. The steering wheel has a rythmic pattern moving back and forth a few degrees. Enough to make holding a full cup or soda not a safe choice unless the desire is to wear the drink. The wobble appears to be a little worse when the car is cold. Winter mornings seem to bring out the worst in the wobble.
I would like to do as much work on my own as possible to save $, but I realize I may need professional service equipment to diagnose some of this. Can car tires be diagnosed for having bulges with some sort of test aside from visual inspection alone? Is there a tool that can be used to verify the metal of the wheel is true and not the source of the wobble? Do wobbles and shakes derive from bad tie rods and/or ball joints? What is the most common problem that produces symptoms similar to mine?
I enjoy the car's money saving potential, but it lacks an air conditioner which is vital for defrost operations and keeping the insane summer heat tolerable. If the repairs will cost me more than the car is worth I may choose to invest that money into a 2005 model as a replacement since I've grown tired of the lack of radio and no air conditioner. I'm trying to keep 5ish years behind the curve as not to waste money on the politics of new car value depreciation.

I have a 2000 Toyota Corolla LE that ran very well until about a month ago. It has about 146,000 miles on it. A month ago it started hesitating from a standstill and the engine ran extremely roughly when trying to move the car. But when I put it in low gear it did much better, although not great! When in Drive it barely moved the car at all and would frequently stop running completely.
When I took it to an auto parts store they hooked it up to their computer and it read out that I needed either spark pugs, spark plug wires, or a new coil. I have replaced the plugs, but that made little difference. I then took it to another auto repair place that told me that it was either a problems with valves, or a 'problems in the lower engine'. I don't know what that latter problems means but either way it sounds like it will be very expensive to fix.

I have a 2004 Toyota Matrix, 5 spd manual with 175,000 miles. It's been a great car, but about 4 months ago I noticed more noise than usual from the engine compartment. It sounds like someone dropped a noisy diesel engine in there! The noise is most noticeable on the highway when the engine is under greater load (e.g. up hill). The dealer told me it's the belt tensioner. I had that replaced, but the noise is still there, and it's getting worse. I recently had the car completely serviced, full tune up, transmission fluid changed, etc.

Those are the codes I'm getting. P0340, P1166 and P1167
Here's the story. Engine running flat under load. Easy acceleration is ok, but merging onto the turnpike causes a noticeable loss of power. Replaced the cam sensor, cleared the codes, ran ok for a day. Same codes came back, same flat performance.
Returned the cam sensor with another new one to make sure it wasn't a dud out of the box. Advance Auto Parts is awesome - replaced it no questions asked.
Installed the new cam sensor, cleared the codes. Ran great for a day, then the same symptoms came back, with the same codes. I'm thinking it might be the ECU? If it is, how expensive are they? And do they have to be programmed by the dealer?
This is a 2002 Santa Fe 2.7l automatic with around 147k miles on it.

In my 2003 Toyota Sienna, the ABS system comes on at low speeds. Since I will be trading in shortly, don't want to pay for costly sensor repair. Looked at fuse box to remove ABS fuse, and found 3 fuses that are labeled as ABS. Which should I remove?
