Toyota Corolla catalytic converter

The neutralizing filter can be ceramic (containing ceramic granules) and metal. Neutralizers made of metal are more expensive, more reliable than ceramic ones, they have a longer service life. Ceramic items are more common, cheaper in price, but also less reliable, since they are fragile, not resistant to mechanical stress. In order to destroy the honeycomb of ceramic option, an elementary strike of an ordinary stone on the bottom of the machine is enough. The neutralizer can also collapse when driving if water gets on it. Malfunctions in the ignition and exhaust system can also destroy the auto filter.

Monometallic Corolla catalytic converter

Monometallic neutralizer is one of the most common but aging types of exhaust system assembly. It is quite simple to understand its structure. The block is formed by thin metal walls of an alloy containing precious or rare elements.

Such a unit has the smallest service life, and the process of extracting valuable elements requires a large consumption of reagents. Therefore, the Toyota Corolla catalytic converter price may vary depending on the grade of the alloy or the composition used in its manufacture.

Bimetallic Toyota Corolla catalytic converter scrap price

The concept of a bimetallic neutralizing filter has long been outdated. Initially, the technology looked like covering the carrier with a thin layer of active materials

Such parts of the exhaust system are gradually falling out of use, in a modern vehicle they are found only in models with a diesel engine. But their number is constantly decreasing. Ceramic items replaced bimetallic devices including its scrap cost. The technology has remained unchanged. The ceramic item is coated with Pt, Pd, and Rh alloys. In some cars, especially American-made cars, not a porous structure is used, but fine granules coated with a catalytic material.

Purchase of a used Corolla catalytic converter

In order not to face unexpected difficulties in the disposal of filters, it is worthwhile to familiarize yourself with the conditions of the recycling company in advance.

They can vary, but a typical list of requirements to accept a Toyota Corolla catalyst looks like this:

1. A ceramic item should be with a minimum number of splits after removal from the casing;

2. For a ceramic filter broken into small parts or into dust, spectral analysis may be carried out or such raw materials are not accepted;

3. Neutralizers with a metal device must be handed over in a tank or unassembled, since otherwise most of the sprayed composition is lost;

4. the presence of impurities in the crushed ceramics (parts of the mesh, sawdust, sand, etc.) is not allowed;

5. ceramics must be handed over dry;

6. parts washed with chemical solutions or soaked in oil will not be accepted.

The Toyota Corolla catalytic converter scrap price depends on many factors. It changes slightly in large cities. The biggest differences are observed depending on the state of raw materials, car brand, model year.

In particular, German brands OPEL, BMW, VW and others are leading in terms of price. The second place is occupied by Japanese (TOYOTA, HONDA and others), the third is held by the French. Next come the Americans, followed by the Koreans.

Estimated price limits (for different types of exhaust filters) look like this:

• ceramics from Germany — from 50 to 100 USD per 1000 grams;

• ceramics from Japan, France and Italy — from 45 to 90 USD;

• metal — the value is set individually, depending on the class (mono, bimetallic), manufacturer, condition;

• ceramics by diesel 40-80 USD;

• ceramics from the USA, star-shaped option — 35-60 USD;

• universal ceramics 10 USD, only complete tanks are accepted.

Items from trucks are considered separately, while the delivery price can reach 250 USD per kg, as well as products of the latest generation (with a unique structure) with a price of up to 100 USD per 1000 g.

Why does the Corolla catalytic converter die?

Let's talk about the reasons why the converter fails prematurely: perhaps this will help you extend its service life as well as save the engine.

1. Fuel with an inappropriate octane rating. Burning out, it melts the cell of the filter, which no longer allows the exhaust gases to pass through;

2. Misfiring in one of the cylinders. Fuel that has not been burnt in the cylinder enters the neutralizer and burns out in it, melting its interior;

3. Overflow of fuel with faulty injectors. The result is the same as in the previous case;

4. Malfunction of oxygen sensors. The lambda sensor, which gives an incorrect signal to the ECU, provokes an overdose of fuel, which burns out the filter;

5. Mechanical destruction of the neutralizing filter. The filling may crack due to shaking (for example, the neutralizer was dropped during repairs), or sharp cooling in an ice puddle while driving. There are examples of chipping ceramics due to factory defects.

Failure symptoms of the neutralizing filter.

The driver may not notice for a long time that the filter is living out its last months. But when melted or clogged cells remain less than half open, the drop in engine thrust cannot be overlooked. Eventually the engine will refuse to move the car forward and a warning light will come on.

Let us clarify that the reason for the failure of this unit can be natural and premature. In the first case, it will be a gradual clogging of the honeycomb with soot, scale and other products of fuel combustion. It is also quite natural for a middle-aged car to become more clogged with carbon deposits from unburned oil rings and unburnt oil, flying out of the cylinders. And as for premature problems, first of all, there is a melting of ceramics or honeycomb metal due to overheating of the exhaust system (above 900 °C). Even if at first the sintering is local, soon the remaining free channels will also begin to overheat due to the increased amount of gases passing through them, and will also become impassable.

A serious problem for the entire engine is fragmentary spalling of ceramics. The trouble is that small pieces of decayed ceramics can be sucked back into the cylinders. Where they work as an effective abrasive and quickly disable the cylinder-piston group — the compression drops, and together with the power. Fortunately, such examples are typical only for some specific motor models. That is why take care of your vehicle in advance and consider a favourable Toyota Corolla catalytic converter scrap price.
