How Many Catalytic Converters Are in a Ford Ranger? [Answered]

Catalytic converter, a small but mighty, is a crucial device in reducing emissions and keeping our environment clean. You will often hear car owners discussing the huge importance of the catalytic converter for their vehicles. One tough question that always comes up in conversation is the how many of catalytic converters in a Ford Ranger?

So, how many catalytic converters are in a Ford Ranger? The number of catalytic converters in a Ford Ranger vary depending on the specific model and engine type. Most Ford Ranger models generally have one catalytic converter per exhaust pipe. That means a Ford Ranger with dual exhaust pipes would have two catalytic converters. 

However, some Ford Ranger models may have more than two catalytic converters, particularly those manufactured for specific markets or emissions regulations. Read on to find out more about the specifics of Ford Ranger catalytic converters.

A catalytic converter is an emissions control device that reduces the harmful pollutants in the exhaust gases of an internal combustion engine. It contains a ceramic or metallic substrate coated with a catalytic material, such as platinum, palladium, or rhodium. As exhaust gases pass through it, the catalytic material catalyzes a chemical, converting harmful pollutants, such as carbon monoxide and hydrocarbons, into less toxic substances, such as carbon dioxide and water vapor.

The number of catalytic converters can vary depending on the Ford Ranger’s model and engine type. Typically, it comes with two – one in each exhaust pipe for dual-exhaust models. But there are cases where more than two might be installed due to additional pipelines or when they’re produced to meet strict emissions regulations specific to certain markets.

In modern vehicles, catalytic converters are essential to the emissions control system. They are designed to reduce the number of harmful pollutants emitted by the engine, such as carbon monoxide, hydrocarbons, and nitrogen oxides. The catalytic converter uses a chemical reaction to convert these pollutants into less harmful compounds, such as water vapor and carbon dioxide.

What Determines The Number Of Catalytic Converters In A Vehicle?

The number of catalytic converters in any given vehicle is determined by a combination of factors, including emissions regulations, engine size, and fuel type. For example, vehicles manufactured for sale in markets with more strict emissions regulations, such as California, may have more catalytic converters than vehicles sold in other markets. Additionally, larger diesel engines may require more catalytic converters than smaller ones.

Another factor is the type of catalytic converter that is used. There are several different types of catalytic converters, including:

  • Two-way converters, which are designed to reduce both carbon monoxide and hydrocarbons
  • Three-way converters, which are designed to reduce carbon monoxide, hydrocarbons, and nitrogen oxides
  • Lean NOx catalysts, which are explicitly designed to reduce nitrogen oxides in vehicles that use lean-burn engine technology

If a Ford Ranger is equipped with a three-way converter and a diesel engine, it is likely to have multiple converters to meet the regulations. It’s also important to note that catalytic converters have a limited lifespan and may eventually need to be replaced. Factors affecting a catalytic converter’s lifespan include driving habits, fuel type, and exposure to extreme temperatures.

So, the number of catalytic converters in a Ford Ranger can vary depending on the specific model, engine type, and emissions regulations. To get the exact information on the catalytic converters in your Ford Ranger, it is best to consult the vehicle’s owner’s manual or contact a Ford dealership or certified mechanic.

What is the Impact of Catalytic Converter Failure on a Ford Ranger?

Replacing a Catalytic Converter
Replacing a Catalytic Converter

When a catalytic converter fails, the symptoms can include reduced engine performance, increased emissions, and higher fuel consumption. In addition to these problems, a failed catalytic converter can also damage the engine and other components of the vehicle. That can lead to more severe issues, such as reduced fuel efficiency, increased emissions of harmful gases, and even engine failure.

The cost of replacing a failed catalytic converter can be expensive, with some estimates reaching up to $2,000, depending on the make and model of the vehicle. In some cases, the cost can be even higher if other vehicle components are damaged. Additionally, driving with a failed catalytic converter can put you at risk of fines and other penalties for breaking emissions regulations.

It is essential to be aware of the potential problems when a catalytic converter fails in a Ford Ranger or other vehicle. Replacing a failed catalytic converter can be expensive and time-consuming, but keeping your vehicle running correctly and avoiding costly repairs is also necessary. Taking the time to inspect and maintain your vehicle regularly can help prevent unnecessary problems and keep you safe while on the road. 

What is the Importance of Proper Maintenance for Catalytic Converters?

Proper maintenance of catalytic converters is essential to ensure their proper function and longevity. Over time, the catalytic converter can become clogged with debris, restricting exhaust gas flow and reducing the converter’s effectiveness. Additionally, the catalysts inside the converter can become contaminated, which can also reduce the converter’s effectiveness. 

Neglecting regular maintenance of catalytic converters can lead to reduced engine performance, increased emissions, and even costly repairs. To maintain the catalytic converter in good condition, do the following:

  • Follow the manufacturer’s instructions for regular maintenance, such as replacing spark plugs and cleaning the air filter. 
  • Avoid running the vehicle on low fuel, as this can introduce debris into the converter. 
  • Avoid excessive idling, which can cause soot buildup in the converter. 
  • Avoid using leaded gasoline or other fuels that can damage the catalysts inside the converter. 
  • Regularly inspect the converter for signs of damage or contamination.

By taking the proper steps to maintain your catalytic converter, you can ensure that it continues to perform optimally and protect the environment from harmful emissions. 


Will a car run the same without a catalytic converter?

No, a car will not run the same without a catalytic converter. Without the catalytic converter, exhaust gases will not be filtered and reduced, leading to higher emissions and decreased engine performance.

Do Ford diesels have catalytic converters?

Yes, Ford diesel engines do have catalytic converters. The type and number of catalytic converters in a particular vehicle will depend on the model year and the engine configuration.

Which vehicles are catalytic converters worth the most?

The value of catalytic converters can vary depending on the make and model of the vehicle, as well as current market prices. Generally speaking, catalytic converters from newer vehicles are more valuable than those from older vehicles. Additionally, catalytic converters for larger engines and diesel applications are more valuable than those for smaller engines.


Catalytic converters are vital in reducing harmful emissions from vehicles and preserving air quality. It is essential to routinely inspect and maintain your catalytic converter to ensure it works properly and does not fail prematurely. Taking the proper steps can help you avoid costly repairs, fines, and penalties. In addition, there are steps you can take to help protect your catalytic converter from theft. Following these guidelines can help keep your catalytic converter functioning optimally and safely on the roads.
