#48 of 78 Re: CHECK ENGINE LIGHT ON AT 62K ON A 2003 HIGHLANDER [akalady_2000] by jrfiero Aug 02, 2008 (5:08 pm)
Replying to: akalady_2000 (Aug 02, 2008 1:03 pm) Please see message 4360 and related posts in the HL Maintenance and Repair forum re O2 sensor replacement. $800 is way too high for the precat O2 sensors, I don't know about the postcat O2 sensor. Toyota calls the precat O2 sensors AFR sensors, same thing. If you've read through the posts on this forum, you'll know that driving for a year with a CEL without knowing the diagnostic code(s) is a bad idea. Re Toyotas or any other cars having occasional problems like the O2 sensor at 60K miles, get over it. Your HL is five years old, and if an $800 repair is all it's needed in five years, that's pretty amazing to those of us who remember when 60K was practically worn out.

I just spoke with a Toyota technican that confirms it sounds like the AFR sensor. I am getting the car serviced first thing Monday. I have had the examined throughout the year (I failed to mention that) and was told various things from gas cap related, to broken fuse.   This forum has been very helpful. Thanks.
#50 of 78 O2 sensor and feul sensor causing shaking?? by hilndr4me Aug 13, 2008 (1:56 pm)
I have an 02 highlander V6 and experienced severe shaking/hesitation on the highway at 100km/hr. Check engine light came on...went to garage and code came up bad O2 sensor. Ordered that part and in the meantime CEL started to blink periodically. Another computer scan now shows that the feul injection sensor? is bad too. Just wondering if these issues will cause the severe shaking of the truck. It's almost as if the engine is coughing and hesitating. If I excellerate it goes away or if I let off on the gas peddle it goes away. I'm really hoping the the two new sensors will fix this because they aren't cheap!   anybody else experience this??

Replying to: akalady_2000 (Aug 02, 2008 1:03 pm) This is probably too late but might be of help as a "cost" guide. I had my 02 sensor replaced not by a Toyota dealership as they add too much charges on it (check-damage fee, parts + $240/hr labor with 2 hrs. minimum). I took it instead to a trusted small time mechanic where I paid around $325 (had only 1 sensor replaced). As far as calling Toyota, I'm not sure it's worth my time and trouble. I was told they don't guarantee the lifespan of "parts" and that 60K is too old for them but hey, you can try. Replies to this message: hilndr4me (Aug 24, 2008 9:47 am)

Hi, We own 2 Toyotas and love them. After owning a VW and an American car, I was just thrilled to have a car make it past 100K without dying or major issues So far I haven't had and serious issues with my HL. It's had all the normal stuff done to it--belts/water pump changed, tires and regular oil changes and service checks, battery, etc. A few months ago though, the check engine light started going on, and then turning off buy itself. Then maybe 3 wks ago the CEL stayed on. Today, I turned it on, and about 2 minutes into driving it, the CEL started to flash, then it stopped flashing and just stayed on.   There haven't been any other noticeable performance issues with the car up until this point except for maybe one thing. Twice (maybe a few weeks ago) I went to start the car in the AM and it gave me a hard time starting (almost like sputtering) but it eventually started and then ran fine.   Since I've had the car for 140K, we've experienced the gas cap issue, the sensor going off for no apparent reason and even the Jiffy Lube issue (where it goes on after you have your car service from there), so I don't think it's that. I'm guessing by reading similar posts that it might be something more serious, like a catalytic converter. What do you think?   Is it time to trade it in/chuck it?

Replying to: toyotamommy (Nov 02, 2008 2:11 pm) We gave up. Maybe we're slow learners, but we traded it in on an '08 Highlander back in May. So far, so good CEL-wise. Replies to this message: toyotamommy (Nov 03, 2008 12:07 pm)

Replying to: toyotamommy (Nov 02, 2008 2:11 pm) Hi I have an 03 w/105k, this am it woudln't start, idling was impossible Had AAA come to tow it but the operator got it started and is running fine. My CEL is not on my question to you is when your HL was "sputtering" was the CEL on? Replies to this message: toyotamommy (Nov 03, 2008 12:01 pm)

Replying to: bikeman3 (Nov 03, 2008 11:31 am) Yes, it sputtered with the CEL on but only when I started it up, and then it was fine.   Took in today to the dealer. What a mess!   They say it has 3 exhaust leaks, 2 air-fuel sensors in the front are bad, one in the back is bad, and 3 O2 sensors and possibly a spark plug/coil need to be replaced. The whole thing would be over $2000. The car is worth around $3500 for trade in if you believe Kelly Blue Book, so I think we're shopping for a new car this weekend. I've had no major issues until now. Very disappointed that I couldn't get it to 200K, but I get 7 good years out of it, and it looks like hell anyway. I'm thinking of getting a new HL I love the car so much!

Replying to: kent17 (Nov 03, 2008 10:51 am) How do you like your 08? I'm thinking about shopping for that this weekend.
