Does the Ford Focus have an EGR valve?

Yes. Most Ford Focus models with combustion engines include an Exhaust Gas Recirculation (EGR) valve as part of their emissions-control system. The electric version of the Focus does not have an EGR valve because there is no exhaust for recirculation.

In practice, the presence and design of the EGR valve in the Focus vary by engine type, model year, and market. EGR systems are standard on modern gasoline EcoBoost and diesel TDCi engines to reduce NOx emissions by recirculating a portion of exhaust gas back into the intake. The exact location, control method (electronic vs. vacuum), and whether a dedicated EGR cooler is used depend on the specific engine family and generation.

Which Ford Focus engines use an EGR valve

Below are the main engine families in Focus models that typically include an EGR valve. Note that the Focus Electric, as a purely electric variant, does not have a traditional exhaust system or EGR valve.

• Petrol engines:
  
  
  
  • 1.0‑litre EcoBoost (three‑cylinder, turbocharged)
  
  
  • 1.5‑litre EcoBoost (three‑cylinder)
  
  
  • 2.0‑litre EcoBoost (found in performance variants such as the Focus ST)
  
  
  
  


• Diesel engines:
  
  
  
  • 1.6‑litre TDCi
  
  
  • 2.0‑litre TDCi
  
  
  • 1.5‑litre TDCi (newer generations in some markets)
  
  
  
  


• Electric variant:
  
  
  
  • Focus Electric (no combustion exhaust; no EGR valve)
  
  
  
  

In short, if your Focus has a combustion engine (gasoline or diesel), it is highly likely to have an EGR valve. The exact implementation can differ by engine code and model year, so checking the specific service documentation for your VIN is the most reliable approach.

Where to find and how EGRs are configured

The EGR valve in Focus engines is typically located near the exhaust manifold or along the exhaust path, sometimes connected to a cooler in diesel variants. It is electronically controlled in modern Ford engines, though some designs may use vacuum-actuated controls. Location and layout can differ between generations (for example, Mk3 vs Mk4 focus models) and between petrol and diesel variants.

Common EGR configurations you might encounter

Here is a quick overview of the typical configurations used across Focus engines:

• Electronic EGR valve with a dedicated control solenoid and position sensor


• High-pressure EGR (provide flow from the exhaust into the intake at higher pressures)


• Low-pressure EGR with separate routing through a cooler (common on some diesel engines)


• EGR cooler integrated with the EGR valve on diesel engines

Understanding the exact setup for your car requires checking the engine code and years, as Ford has updated EGR layouts across generations.

Symptoms of EGR problems in the Focus

Before diagnosing, note the typical warning signs that may indicate EGR issues in a Focus with a combustion engine:

• Rough idle or hesitation at low RPM


• Check Engine Light with EGR-related codes (e.g., P0401, P0402, P0403)


• Reduced fuel efficiency and ongoing emissions concerns


• Loss of power or sluggish acceleration, particularly at low speeds


• Excessive engine idling noise or increased exhaust smoke in extreme cases

If you notice any of these symptoms, a professional diagnosis is recommended, as EGR issues can also stem from related components like the EGR valve, cooler, or associated wiring and sensors.

Maintenance and diagnosis tips

Proper maintenance can prevent many common EGR problems or catch them early. The following steps are commonly advised for Focus EGR systems:

• Check for diagnostic trouble codes (DTCs) with an OBD-II scanner to confirm EGR-related faults


• Inspect the EGR valve for carbon buildup and clean or replace if necessary


• For diesel engines, inspect the EGR cooler for leaks or clogging and test cooling performance


• Ensure fuel and oil choices are appropriate to minimize buildup and deposits


• Replace the EGR valve or cooler if cleaning does not restore proper function

Regular maintenance and timely replacement of worn EGR components help maintain engine efficiency and emissions performance, especially in diesel variants where buildup can be more pronounced.

Summary

In summary, the Ford Focus generally includes an EGR valve on its combustion-engine variants to meet emissions standards, while the Focus Electric does not have one. The exact arrangement—valve type, location, and whether a cooler is used—depends on the engine family and model year. If you’re experiencing symptoms such as rough idle, a malfunction light, or reduced fuel economy, an EGR system check is a prudent first diagnostic step, preferably with a qualified technician who can confirm the specific configuration for your Focus and perform cleaning or replacement as needed.

What cars do not have an EGR valve?

Electric vehicles do not have an EGR valve, as they do not produce tailpipe emissions.

Does a 2012 Ford Focus have an EGR valve?

The EGR, or exhaust gas recirculation valve, is found on the engine of your Ford Focus. The EGR valve limits the amount of exhaust gas that goes into the outside air by rerouting some of it back into the intake manifold so it can be burned during combustion.

What years of Ford Focus to stay away from?

The Ford Focus years to avoid are 2012-2016, due to major issues with the automatic PowerShift transmission. Other years to avoid include 2007 and 2008 for electrical and steering problems, and 2017–2018, which had lingering transmission and other issues, although fewer than previous years.

Problematic model years

• 2007–2008: These models are associated with faulty electrical systems, door handle failures, and frequent issues with steering and suspension. 
• 2012–2016: This range is considered the most problematic, primarily due to the PowerShift dual-clutch automatic transmission, which frequently failed and is expensive to repair. Problems included hesitation, jerking, and complete failure, often before 100,000 miles. Some models in this period also had issues with power steering and electrical glitches. 
• 2017–2018: While improved, these years still saw some lingering transmission problems and sporadic electrical issues. 

What to look for in other model years

• Manual transmission: The problematic issues mainly affected the automatic versions of the third-generation Focus (2012-2018). Models with a manual transmission from this period are generally considered more reliable. 
• Earlier models (pre-2012): While not entirely trouble-free, models before 2012, especially around 2011, are often seen as more reliable than their successors due to simpler transmissions. 
• Later models (post-2016): The 2018 and 2019 models are often praised for improved reliability and handling.

• Frequent Stalling. Frequent stalling is when the engine unexpectedly stops running, often while idling.
• Rough Idling.
• Knocking or Pinging Noise.
• Poor Engine Performance.
