2005 Sequoia Stalls after cornering (solved)
 

My 2005 Toyota Sequoia was experiencing power loss, stalling, failure, holy shit I have no power, my engine just dropped out and I am in traffic. I have been experiencing this for a year or more and it was getting worse leading up until now. I was at a loss, my wife was scared to drive the truck for fear that it would die and stay dead. What it did do was after making a corner, whether stopped or rolled through, then applying the gas, either WOT or easing into it (pulling into traffic). So in a scientific manner I made laps last night getting the power to cut out every single damn time.

Some intense internet researching with different keys words landed me with the suggestion to conduct a zero point calibration. The only thing was that the folks saying this should be conducted had VSC lights on and holding on the dash. I though what the hell it couldn’t hurt.

Zero Point Calibration - Toyota Nation Forum : Toyota Car and Truck Forums


Did as the instructions said, then drove it again. This time the VSC engaged with the blinking skid light, then an audible alarm, then reduction of rpms, for 1-2 seconds, and back to normal. I could not get the truck to repeat the loss of power for no apparent reason. Zero Calibration worked in solving this problem.

What a relief it must be to have this solved, and nice work.

Thanks for posting this.

I lied it still does it. Now we nicknamed it the Murdersequoia.

2005 Toyota Sequoia SR5 2wd. This is extremely frustrating but we will get through it. The murder sequoia is still at it trying to kill me. To date I have unplugged and run the vehicle with the following. VSC plug on the brake fluid reservoir, lights (VSC, Trac, ABS) came on no change in performance. Yaw control module under the center console, lights (VSC, Trac, ABS) came on no change in performance. I have also replace the throttle position sensor (non wire on the 2005) with a used one, no change in performance. Replaced the Mass Air flow sensor because I had a trouble code, no change in performance.

What other sensors feed the VSC or ECU that would shut the vehicle down almost every time at the same set of environmental and input variables? Steering position sensor? Trans Fluid change? Rear shocks? I just don’t know but it’s to the point that I’m thinking about a low mileage 2007.

I gave up attempting to fix this myself and took the vehicle to Toyota. Prior to doing so a friend offered the use of his Snap On Diagnostic tool, it gave us a C1362 (VSC Set value Failure). We cleared it, and waited. A few days later the symptoms returned and to the dealer I went, also got a air bag recall fixed as well.

The service tech didn’t understand much of what I was saying and made the face my wife does when I’m explaining something technical that she isn’t interested in. I asked for a mechanic to translate, we did and they kept Harriet (2005 Sequoia) for a few days. They called and said they couldn’t find anything so they did the air bag and charged me $0.

A few days later is was back to acting up and I returned it. They called a few hours later stating they could not get it to start, and I said yep it does that too, fix it. They called later that afternoon and said they thought it might be an $80 fuel relay (I swear I changed that), I said what the hell, do it!

I picked it up and drove the shit out of it, high speed corners, drag strip take offs from the light, lane maneuvers on the interstate dropping gasped then accelerating rapidly. Nothing fazed Harriet, she was back to normal. We are now on week 3 and Harriet is performing much better. A slight increase in fuel, performance, and a huge increase in safety. I’ll update if anything changes.

Glad to hear you got it figured out. What was the part # of the fuel relay? Just in case any other 4.7l owners have this issue.

I suspect your nickname is Ozzie?
 

Thanks for the post. I have a 2000 Tundra and any Gen 1 tips are welcome.

That's a crazy fix @xcmountain80 . To think a fuel relay fixed it all, interesting.
Been trying to help a friend of ours, 2001 Sequoia 4wd. Same lights are on, ABS, trac, VSC. Low power feels like something is tied in the back of the Sequoia.
Our friend did get talked into a generic steering rack, which I think is tripping the dash lights. Maybe during that the Zero Point calibration got messed up.
