Quite simply, Bank 1 refers to the side of the engine that has the #1 cylinder. Bank 2 is the opposite side of the engine. Even on cars with a tranverse mounted engine, bank #1 is referring to downstream from the side of the engine with cylinder #1.
Catalytic converter replacement isn't cheap. For most vehicles, the average cost of a catalytic converter repair is between $945 and $2475 including parts and labor. The catalytic converter cost itself can be up to $2250 of that.
A new catalytic converter can cost $1,000 or more, making it among the most expensive individual parts on any car. They are costly because they use expensive metals such as palladium to promote the chemical reactions that cleanse the exhaust. In theory, catalysts can be used over and over, indefinitely.
It's highly advisable to replace a totally blocked catalytic converter. If they are partially blocked, soak the catcon in a mixture of degreaser and hot water. Check it from time to time and once the clog has been removed, dry it up completely before putting it back in your car.
Among the symptoms of a bad catalytic converter are:
- Sluggish engine performance.
- Reduced acceleration.
- Dark exhaust smoke.
- The smell of sulfur or rotten eggs from the exhaust.
- Excessive heat under the vehicle.
If the engine responds sluggishly or quits after running for a while, a clogged converter could be to blame. Catalytic converters can overheat because of excessive amounts of unburned gas caused by a misfiring spark plug or a leaky exhaust valve. In addition, a failed oxygen sensor can cause overheating.
Basically, if it's clogged, fix it. If the efficiency of it is gone, don't worry about it unless you live in an area that checks emissions. It affects no sensor that's actually relevant to the engine. A plugged catalytic converter will only in extreme cases prevent you from driving your car.
It Can Be Driven Indefinitely
A plugged catalytic converter will only in extreme cases prevent you from driving your car. You can usually drive your car indefinitely with a partially plugged converter, though you will see a drop in performance.What repairs can fix the P0420 code?
- Replace muffler or repair leaks in the muffler.
- Replace exhaust manifold or repair leaks in the exhaust manifold.
- Replace exhaust pipe or repair exhaust pipe leaks.
- Replace catalytic converter (most common)
- Replace engine coolant temperature sensor.
- Replace front or rear oxygen sensor.
Although you will definitely want to check the oxygen sensors first. If you are in a position to test them It's not unusual for code P0420 to come on, stay on for even a few days, and then just disappear. Then, months later, it might happen again (i.e., appear and disappear).
Quick ways to fix a P0420 code:
- Check the exhaust system for potential leaks.
- Use Catalytic Converter Cleaner to remove any build-up in the system.
- Fix or replace damaged oxygen sensors (special tool required)
- Replace the catalytic converter.
Typically yes. Your vehicle can operate without a Catalytic Converter. It may throw an engine fault code as it does look for the catalyst to filter before reaching the rear oxygen sensor present in your exhaust system to adjust fuel curves or Air to Fuel ratio. There are work arounds for this.
OBD II fault code P0420 is a generic code that is defined as “Catalyst System Efficiency Below Threshold (Bank 1)”, and is set when the PCM (Powertrain Control Module) detects a condition that indicates that the catalytic converter on Bank 1 is operating below the minimum allowable efficiency threshold.
The next most expensive catalytic converter is a bit closer to home. The Dodge Ram 2500 comes in at $3,460.00. The Ford F250 (similar to the Dodge 2500 in terms of towing and strength) is a mere $2,804.
Quite simply, Bank 1 refers to the side of the engine that has the #1 cylinder. Bank 2 is the opposite side of the engine. It's not correct to simply state that driver's side is always cylinder #1 or vice versa.
Once the delicate metals or ceramic materials inside the converter have been damaged, there is little you can do. You'll need to bite the bullet and purchase a replacement. If you take it to a local shop to have it replaced it could cost you well over $1,000 in parts and labor.
Some manufacturers may assign the left side of the engine as Bank 1 and the right as Bank 2. The best way to determine which side is Bank 1 or Bank 2 is to check the vehicle's service manual. On most vehicles, Bank 1 is referring to the side of the engine where the #1 cylinder is located.
Long-term solution: invariably the factory converter must be used for the permanent repair. Here, the price of the job will rise into the $1200 to $1500 range, possibly higher on exclusive models. Keep in mind, pricing will vary by location and your vehicle make and model.
Several of the most obvious signs that the oxygen sensor is failing include:
- Reduced gas mileage.
- A bad smell like rotten eggs coming from the exhaust.
- The check engine light comes on.
- You notice that your engine idles roughly.
- The car is suddenly hard to start.
In your case, the P0420 code stands for “Catalyst System Efficiency Below Threshold (Bank 1).” When you receive a P0420 code it means your catalytic converter is not operating at maximum efficiency. Usually this means your catalytic converter needs to be replaced or there is a problem with your O2 (oxygen) sensors.
3. Rough engine idle and misfires. Since the oxygen sensor output helps control engine timing, combustion intervals, and the air to fuel ratio, a bad sensor can disrupt these engine functions, causing a rough or irregular engine idle and other engine-related issues.
Bank 2 Sensor 1 = This O2 sensor is located right before the catalytic converter, on the side with the Cylinder #2 that is Bank 2. Bank 2 Sensor 2 = This O2 sensor is located right after the catalytic converter, on the side with the Cylinder #2 that is Bank 2.
The product that you can use is the OXICAT – Oxygen Sensor & Catalytic Converter Cleaner . You tap it into your fuel tank, and it does not matter if you have a petrol, diesel or hybrid car. This will help not just to clean the catalytic converter; it will also clean your O2 sensors and the whole exhaust system.
Bad Spark Plug, Wire, or Fuel Injector
Any of these can cause one or more cylinders to misfire. This makes the computer think it's not injecting enough fuel. The danger is that the extra fuel injected to compensate eventually winds up being burned in the catalytic converter.What repairs can fix the P0420 code?
- Replace muffler or repair leaks in the muffler.
- Replace exhaust manifold or repair leaks in the exhaust manifold.
- Replace exhaust pipe or repair exhaust pipe leaks.
- Replace catalytic converter (most common)
- Replace engine coolant temperature sensor.
- Replace front or rear oxygen sensor.
The Infamous Trouble Code P0420
OBD Code P0420 means the catalyst system efficiency is below the threshold. When a mechanic sees error code P0420, he or she will tell you that you need a new catalytic converter. This trouble code appears when the unit can't sufficiently reduce the carbon emissions from the exhaust.The 420 code is a result of the ECM not liking the data from the A/F and O2 sensors. If your engine is running properly, it's going to be cat or sensor. The gas cap will throw an evap emissions code.
In your case, the P0420 code stands for “Catalyst System Efficiency Below Threshold (Bank 1).” When you receive a P0420 code it means your catalytic converter is not operating at maximum efficiency. Usually this means your catalytic converter needs to be replaced or there is a problem with your O2 (oxygen) sensors.
The most common things that can cause a P0420 error code are bad oxygen sensors, engine coolant temperature sensor malfunction (does not seem likely given what you have said), leaking exhaust, or a bad catalytic converter. It could also have caused leaks elsewhere in the system.
In your case, the P0420 code stands for “Catalyst System Efficiency Below Threshold (Bank 1).” When you receive a P0420 code it means your catalytic converter is not operating at maximum efficiency. Usually this means your catalytic converter needs to be replaced or there is a problem with your O2 (oxygen) sensors.
If the rear O2 sensor is getting faulty values, the p0420 code will get stored in the engine control unit. It could be because the catalytic converter is defective, or a false alarm because one of the O2 sensors is damaged.
