#4366 of 5330 Toyota Highlander 2002 4 cylinder Oxygen Sensor location
Aug 11, 2008 (12:42 pm)
I need help to determine location of Oxygen Sensor 1 for Bank 2 (P0141) and Sensor 2 for Bank 2 (P0161). I saw the forum mentioned there are only two sensors but when I opened the hood there are for sensors (two for each sides, driver sides and passenger sides). I believe there are two heater sensors and two oxygen sensors. I requested the dealer to fax me the diagram, it shows three instead of four.
#4367 of 5330 Replaced my brake pads
Aug 18, 2008 (4:24 am)
I just replaced the brake pads on all four wheels of my 2001 V6 Ltd with just over 68K miles. None was down to the squealers, but the fronts were close, less than 3mm. The rears were only slightly less worn.
It couldn't be any easier to change the pads on this car. I had a little trouble with the dust boot on one piston not wanting to go back into the caliper with the piston, but other than that it was a cinch.
#4368 of 5330 Torn shock boots
Aug 18, 2008 (4:28 am)
While I was replacing my brake pads, I noticed the boots on both rear shocks/struts are torn and useless.
1) is this a big deal?
2) I suspect its a major operation to replace them, removing the springs and all. Does anyone have any experience with such things?
The other thing I noticed while replacing the brake pads is that Nitrile gloves from Home Depot are junk. They tear with the slightest provocation. Nitriles are supposed to be tougher than your basic latex gloves, but these aren't. Buy 'em somewhere else.

Forget those thin nitrile gloves, they are too flimsy. I use a good pair of CLOTH GLOVES with the Nitrile covering that covers the fingers and inside of the palm of the glove, these are tough and last a long time, available at any auto parts store. The brand I bought was "Workwear", but I am sure most any brand of the same type gloves would be good. I have used mine for a year on many tough jobs, including doing an engine rebuild, several brake jobs and general servicing, and I throw them in the washing machine to clean them. Great gloves, they have made doing my mechanical work much easier and cleaner.

Aug 20, 2008 (4:26 am)
I have the same problem and the same Toyota Highlander 2002.
Did you ever find out the problem and solution?
I have gotten several codes off the ecu scan and I am not sure what they will require to resolve the problem. The codes are:
P0440 EVAP Emisison Control Malfunction
P0441 EVAP Emission Control System Purge flow fault
P0446 EVAP Emission Control Vent Circuit Malfunction
#4371 of 5330 Re: ABS intermittant fault [quattrohead]
Aug 26, 2008 (5:22 pm)
I became bad enough that a trip to the dealer was in order. They diagnosed bad ABS sensor signal from the right rear. They wanted to replace the sensor at a cost of $525...checked online and found the price to be under $200. Ordered and replaced and still the same.
I do see that the teeth on the hub are not totally clean, so how does one get to them to clean properly ?
#4372 of 5330 2002 HL excessive oil consumption
Aug 26, 2008 (6:26 pm)
I have an 02 HL V6 AWD 90K miles. Always serviced at dealer with shorter than recommended intervals. Hopefully someone can help with this problem.
Last Spring CEL comes on. Check oil, level is low. Add oil. Continue checking oil and note continued consumption. Discussed with dealer and they top off oil and I bring back twice. After 500 miles oil is 1 quart low. Next time after 900 miles oil is almost 2 quarts low. Dealer agrees oil comsumption problem.
Also, have intermittent exhaust smoke on startup.
I'm aware of and have the paperwork for the oil sludge settlement of which my HL is covered. Make my case to the dealer that blue smoke and oil consumption is covered under this settlement. They remove valve cover ($125) and say no sludge problem therefore not covered under the settlement. Dealer says must be something else. SA tells me $5K to rebuild engine if that is the problem.
I call number on settlement paperwork (Toyota corporate), give them details. They have dealer SA call me back and say they need to again remove the valve cover to determine the problem (another $125). He says that they may have to do some type of pressure test, doesn't give cost. He also says that if problem is valve guide the cost is all mine. If the problem is bad rings, Toyota will share in the cost, whatever that means.
If anyone can provide any input/advice on this topic it would be greatly appreciated. I know very little about engines.
Also, I read on post on Edmunds that indicated that a clogged PCV valve could cause excessive oil consumption. That's apparently a $10 item. Can anyone verify if this could be the problem.
Does anyone know the cost to repair valve guides or the cost to repair bad rings?
thanks in advance for any solutions!!
#4373 of 5330 2007 HL Engine Noise at 20 and 40 mph
Sep 03, 2008 (5:10 pm)
I have read through most of the noise complaints on this 2007 HL with 16K miles and have not seen this one!
At about 20 mph and again at 40 mph a noise that I can only describe as a continual hardly audible 'whoop,whoop,whoop' begins and lasts until I pass through each range. Most noticeable when climbing a moderate to steep grade.
I thought about the tires (just replaced with Costco's BFG Touring) - but noticed that when I take my foot of the gas pedal, the noise stops. This has to be in the drive train somewhere.
Any ideas what it is - and how do I reference this problem to my dealer/service repair?
Sep 05, 2008 (3:46 pm)
I've got an 04 Highlander, 39K miles, 4 cyl, A/C blowing air that is barely cool. I did a pressure test, checked out fine, but the compressor is not cycling on. Any ideas?

Ecotrklvr, you still here?
I'm having the high idle problem on my V6.
How long did the positive results from your cleaning last? I noticed in another post you recommended replacement rather than cleaning.
Anyone else with ISCV experience, or other cures for high idle? I'm talking over 2000 rpm warm, occasionally drops lower. Pretty annoying.
