Can you send me the rear passenger oxygen sensor location diagram?

The Sequoia has two oxygen senros that are bolted into the exhaust pipes coming out of each manifold. They are located roughly under the front seats. There is a known problem with the Sequoiua's oxygensors not being properly bolted into the flange. The two nuts will cecome loose and fall off, and if you suddenly accelerate, the oxygen sensor pops out (of course it will be dangling). You have to put it back with new gasket and new nuts.

Exhaust leak for a 2001 exhaust leak

Check your exhaust manifolds. I had one and the exhaust manifold on the back side against the firewall cracked. Of course it was the one that is hard to get to and not the easy one. You will probably need to remove some heat shields to get a look at it. On mine it was easier to look at from underneath the car. But be sure to check your muffler and exhaust pipe as well for damage or possibly rusted out. Start the car and track down where the noise is coming from. If you end up finding that one of your exhaust manifolds is cracked I recommend buying an OEM one and not an aftermarket one. They will tell you that the aftermarket one might have a lifetime warranty but that does not include labor. I bought an aftermarket one and a few months later it broke and I ended up buying and OEM one and put it on and had no more problems.

The left and right exhaust manifold gaskets were replaced on my 2001 toyota sequoia but I still hear a ticking noise. What could be the problem?

Theres a leak somewhere, make sure theres no cracks in the manifold or a worn gasket at the connection pipe, heres apuicture of your exhaust to show you where to check, also the manifolds should of been checked when the gaskets where replaced, these vans are known for breaking exhaust manifold bolts, hopefully they didnt try to replace the gaskets with a broken bolt,hope this helps.1752005.jpg

2001 Toyota Sequoia is showing a P0505 and PO420 error code; how do you correct these issues.

P0505 Idle Control System Malfunction

IACV or Idle Air Control Valve if equipped is malfunctioning.

P0420 Catalyst System Efficiency Below Threshold (Bank #1)
The Catalytic converter is not working up to par in Bank#1.

I think this will point you in the right direction..

You may have a crack in crossover pipe on driver side near exhaust manifold where it bolts to crossover pipe flexing from engine movement opens crack on acceleration, check for cracks on both sides driver and passenger.

Leak in Exhaust Manifold after catalytic converter replacement.

it depends if they took the manifold off to do the cat converter job
If they did it is their repair cost as the job was not completed properly
if that was not necessary then they may have broken the flex bit just from the manifold

Exhaust smell in cabin of 2001 dodge ram

Is it exhaust or is it a fuel smell? Exhaust, i would say you almost have to have a leak, check the manifolds and the head pipe really well. Check to see if ti even has an EGR valve at the rear of the intake to the top of the intake manifold, it depends on the emissions label it has under the hood, federal or california. If it is more of a fuel smell check to be sure all of the charcole canister lines and hoses are hooked up and not gone or broken.

Loud noise from exhaust front end ..check engine light on dash permanent display, hyundai accent gsi 2001 manual says emission problem..make appointment with dealership, can't afford at moment...I...

Start the car open the hood. with the hood open listen and smell for the leak. Probably the frt exhaust manifold leaking. Independent mechanic can repair just as easy. No need for dealer. If the leak is bad enough you will smell exhause leak. Look for the area with the greatest amount of noise.
