#1941 of 2179 Sequoia Camshaft sensor replacement
Jul 16, 2009 (5:43 am)
At 209,000 miles I can honestly say I have yet to replce any engine components - either due to wear or failure on my 2001 Sequoia. The vehicle and powertrain continues to amaze me. I have replaced 4WD seals and the Diff once under warranty, and had the intake manifold leak air which necessitated rrplacement at 99,000 just inside warranty $(1300). But other than brakes and O2 sensors (Check engine light) and the PRNDL light on dash - not even a light bulb replacement! I tried aftermarket Sylvania headlights to improve my night vision but they failed after 1 yr and Sylvania even agreed that was 'Normal for "High performance" bulbs"\' - but sent me a replacement coupon - So when they failed again in another year I put the original Toyota bulbs back in and they're still going strong. So much for Sylvania manufacturing and hype - or maybe Toyota QC.

Wondering have you also not changed the timing belt?

Expected wear and tear.

Thanks, canddmeyer. I asked the question because after owning 7 Toyotas over the last 38 years (Tercel, 3 Camrys, Highlander, Corolla and Sequoia) this was my first camshaft sensor issue with any vehicle.

I know this reply is a year and a half late, but I found it when I went looking, so I'll reply just in case anyone else finds this. I have a 2001 Sequoia LTD, and we had it in to the dealer for a check engine light on. The dealer ran the codes, and told us we had two bad catalytic converters and a bad rear oxygen sensor. Their estimate: $4000 for the repair.
Now this sounded a bit fishy to me. I've heard of catalytic converters going bad, but not on a vehicle only 8 years old.And for sure not two at the same time. Way too much of a coincidence!!
So I went to a mechanic friend of mine and asked him the question. And he said there was a good chance that just replacing the bad oxygen sensor would correct all of the codes. So I bought a new sensor at AutoZone ($129), rented a car code reader. The code reader "confirmed" what the shop had said - both catalytic converters and one oxygen sensor had trouble codes. I swapped out the sensor (15 minute job), and cleared the computer (pulled the negative battery cable off for 5 minutes). Sure enough, when I redid the code read, it came up clean - no problems.
So for $129 and 15 minutes, I saved $4000. Not bad. But I think that buys me the right to complain a little. This is speculation on my part, but it seems like the only sensor points that could show a problem in either catalytic converter are the two rear oxygen sensors. And if one of them is showing a trouble code, couldn't that be the cause of the catalytic converters showing trouble codes?? It's kinda like saying, "That sensor is broken, but it is still working fine." I would think the dealer would at least say, "You have a bad oxygen sensor and POSSIBLY two bad catalytic converters. But we need to change the oxygen sensor before we can be sure." Come on - two catalytic converters coincidentally failing at exactly the same time?? The dealer is supposed to be smarter than I. How come this sounded suspicious to me, but not to them? So I'm not saying the dealer was crooked (after all, the codes for two bad catalytic converters and a bad sensor did show up on the computer). I'm just saying that it is not a bad thing to get a second opinion for any larger repair, even if it is a dealer telling you that you need it....
#1947 of 2179 Extended Warranty - Too Many exclusions, not a good ROI
Jul 28, 2009 (3:14 pm)
Just venting here. I purchased my 2004 Toyota Sequoia with an extended 7 year 100k platinum warranty. Never needed until recently when 1) the Drive light on the dash board went out, not a huge deal but when the car is in Drive, the instrument panel is blank. Anyway it was not covered because it was considered a light bulb, even though it is not really accessible for the normal driver, so that sucked!!. 2) The check engine light came on the other day , took it down to the dealer to fix the problem, thought to myself, good think I bought that extended warranty since it didn't apply to the drive light at least I get some ROI here. They came back and stated it was a P0441, P0446 EVAP system leak detected and stated, I left the gas cap loose (which I didn't and would be the first time in 5 yeer expressing my displeasure with the service director, he said he'd split the cosars). Plus tank was haft empty... does it take 4 days for a light to turn on? Thank you very much, now bend over and take this.....$131 diagnostic fee, What a rip. I told them about the great platinum plan i bought and how they said it would cover everything, but then he states that they have nothing to do with the extended warranty stuff, Getting upset, I told him I bought the extended warranty from Toyota, the same name embroidered on his shirt and on his paychecks so please do tell me they have nothing to do with the extended warranty (sigh)..Anyways he offered to split the diagnostic fee, so I paid $65.50 which was a little less painful. Wondering if I should bring it back if the check engine light comes back on, just for them to tell me i left the gas cap loose and charge me $131 again. Funny if they had found a problem, there wouldn't have been a charge, but because they didn't they had to charge me. Save your money and don't go with the extended warranty. The 2 times I tried to use it I got denied. My two cents.

I empathize with your experience. I also believe that your extended warranty is good at ANY repair shop not just Toyota - so cultivate a relationship with a trustworth place that has good equipment and can work on Toyotas. That said, replacing the PRNDL (park,reverse, neutral....) lite as its called, was quoted to me on my 2001 Seq at 190k miles for $125. I balked, having just had 2 Toyotas in for timing belt replacement - about $1800 for both - so out of the blue the dealer called me the following week for a FREE PRNDL lite replacement - good PR I think. On the Diagnostic charge - I have been charged $65 to tell me my check engine lite was ON because my Brake Fluid was low. I was burned but now having a techician in the family, I understand fancy dealers need to recover techician time regardless of the simplicity of the fix, else have few tech's on staff - which hurts us all. Save for the few Check engine and Oxy sensor issues, my 2001 has been a rock compared to the Yukons and Explorers of the world.

I have read most of your posts with intense interest. Even though there are a few bad ones out there I can assure you all that toyota makes a superior truck. I have a 2002 with 130,000 miles. I have changed the timing belt at 110k which I admit is late, changed the oil on time, flushed the brake system, lubed the chassis and besides consumable parts like brake pads and roters, one battery and a set of michelins I have had no problems with my seqoiua. I am a bit disturbed by the clicking noise from the engine but the explanations I received from this forum seem plausible. The noise has not hurt the performance. I recently looked at a new sequoia but the one I have runs just fine so i changed my mind. I guess this is the opposite of venting. I'm happy.

I had to change the O2 sensor today on my Sequoia. The one I bought at Auto Zone had different color wires than the old one I took off. I could not make heads or tails of the directions on how to match the colors correctly. I went back Auto Zone and the guy didn't know any more than I did. Can anyone tell me how to wire up the new O2 senor to the plug that plugs into the wiring harness?
