On any vehicle after 1996, YES.
It the caralytic converter is clogged you may do serious damage to your engine. At the very least you will get very poor mileage. I would repair this before taking a trip of tha distance. Common sense should apply.
In a nut shell, there is gas that is getting to far unburned. There is damage being done to the Catalytic Converter. Get it fixed asap. Cats are expensice, not to mention the beating your fuel mileage is taking.
It is part of the y pipe and must be cut out to remove without taking the y pipe
If your check engine light is blinking with the engine running , an ignition misfire has been detected . Take it in and have it scanned for trouble code(s) in order to diagnose and repair the problem . Try not to accelerate quickly while taking it in for repair as this could damage the catalytic converter(s)
Most likely a partially plugged catalytic converter Or engine misfire Is the check engine light on?? If not have your exhaust backpressure checked
Since the combustion of a fuel is taking place, water must also be a product.
Dismantlers attempt to salvage vehicles by taking apart cars so that the parts can be sold for scrap. Dismantlers use tools such as catalytic converter cutters to remove valuable parts from old cars.
There are 2 sensors. One located within the engine compartment mounted on the exhaust pipes next to the engine block. The other is located next to the catalytic converter. As far as the code is concerned, consider taking out the sensor, clean it and reinstall it. Erase the code. Run engine for a couple of days. If the code comes back you should then replace the old sensor with a new one.
from what i see the intake is all that has to come off. about 3 hour labor cost for that. while they are doig that go ahead and get your plugs changed and check out the coil packs under there. also i would spend the extra $50 on the o2 sensor. you have to take the intake off for all of this
It is illegal everywhere. They are covered by federal law. Taking it off won't make your car go any faster, if that's what you think, unless it's plugged, in which case you can buy an after market unit and weld it in.
This references the 2001 Toyota Sequoia: There are four O2 sensors on the Toyota Sequoia. There are two exhaust systems on the Toyota Sequoia: one is located under the drivers side and the other is located under the passengers side. Each exhaust system has a catalytic converter on it. There are two O2 sensors on each exhaust system: one O2 sensor is installed in front (engine side) of the catalytic converter and one behind the converter. The O2 sensors are referenced by 1) Bank - which side it's mounted on and 2) whether it's the front or back sensor. Bank 1 references the drivers side exhaust system. Bank 2 references the passenger side exhaust system. Sensor 1 is in front of the catalytic converter (nearest the engine). Sensor 2 is behind the catalytic converters. Each sensor is referred to by their position on the vehicle i.e.: bank 1 sensor 1 describes drivers' side, engine side of the catalytic converter. You have to access these sensors from under the car. The O2 sensors are screwed into threaded plates welded onto the exhaust piping. They are all electronically connected within a few inches of the sensor with environmental plugs. The rear sensors are fairly easy to remove and the front ones are more difficult. The bank 1 sensor 1 (driver's side, forward) is extremely difficult to access and sometimes requires the owner taking the vehicle to a Toyota service center for replacement. Note that an estimate at a Little Rock Arkansas dealer was ~$800 to replace that sensor in 2009 due to having to remove the header to access the sensor. Toyota Sequoia sensors are very expensive as compared to many other vehicles.
I have replaced once about 10 years ago and it needs it again. I just want to make sure than the mechanic is not taking me for a ride. He says we might have to also replace the catalytic converter, because it has been replaced once. Help!!!!These are common failure items.The Catalytic converter will go bad every 60,000 to 120,000 miles on average. Longer if you can stay on good fuel. The flex pipe is an item that can fail because they do OR:It had a bump or bang the wrong way.Its in use in Canada during the winter. (They use so much salt I think plastic will rust )An engine mount has gone badThere is an exhaust leak between the engine and it.Get a second opinion and have those things checked.
