P20BA Code On 6.7 Powerstroke: What and How to Fix It?

Ford created the 6.7 Powerstroke diesel engine for their Super Duty pickups. It has the same issues as other engines.

P20BACode may cause power loss and engine stalling. This handbook explains the P20BACode and how to fix it.

Follow these methods to get your machine up and running again quickly.

What Does P20BA Code Mean?

In the automobile industry, the P20BA code is used to indicate an issue with the engine. This OBD-II error code indicates a problem with the vehicle’s exhaust gas temperature sensor.

The exhaust gas temperature sensor monitors an extremely important parameter for engine efficiency: exhaust gas temperature.

When the EGT sensor reads a temperature that is too high or too low, it will set off the P20BA error code.

A defective sensor, a blocked catalytic converter, a malfunctioning exhaust gas recirculation (EGR) valve, or a leaky exhaust system might all contribute to this problem.

As soon as the P20BA code is triggered, a thorough diagnosis must be performed, and the problem must be fixed. If not addressed, the condition may worsen and cause engine damage, poor performance and fuel efficiency, higher emissions, and even engine failure.

A technician will begin troubleshooting by verifying that the EGT sensor is functioning properly.

After that, they’ll look for leaks or obstructions in the exhaust system, EGR valve, and catalytic converter. If any of these parts are defective, replacement is required.

What are the Symptoms of Getting the P20ba Code on a 6.7 Powerstroke?

If you get the P20BA error number on your 6.7 Powerstroke, the diesel particulate filter (DPF) system is having some issues. The following is a list of possible symptoms associated with obtaining this code:

  • Clogged DPF filters reduce engine performance because they prevent harmful particles from entering the engine. These particles include soot and other combustion byproducts. Possible effects include worse performance overall, slower acceleration, and worse fuel efficiency.
  • PDF DPF filter was developed to lessen the quantity of black smoke produced by the exhaust system as its use became more widespread. The amount of black smoke released increases as the filter gets blocked.
  • When the onboard diagnostics system identifies an issue with the DPF system, it will cause the Check Engine Light to light.
  • Exhaust temperature rises because of restricted exhaust flow caused by a clogged DPF filter. The engine may overheat as a result of this.
  • Exhaust noise escalation: If the DPF filter becomes clogged, the engine will work harder to discharge the exhaust gases, increasing exhaust noise.

Factors Causing Error Code P20BA

Diagnostic trouble code (DTC) P20BA is an available powertrain DTC that indicates a problem with the diesel particulate filter (DPF) regeneration.

When the engine control module (ECM) determines that the DPF has not been regenerated, despite the prerequisites being satisfied, it sets this code, which is diesel-engine-specific.

The following are some of the most typical reasons for this code:

  • Faulty Diesel Particulate Filter (DPF): A DPF that has become soot-clogged may cause a reduction in exhaust flow and the subsequent storage of fault code P20BA.
  • Inadequate Exhaust Gas Recirculation (EGR) Due to Carbon Buildup, the EGR valve may get blocked with carbon deposits, reducing the quantity of exhaust gas recirculated. As a result, the error number P20BA may be recorded, indicating incomplete combustion.
  • Malfunctioning fuel injectors may raise fuel pressure and allow unburned fuel to enter the DPF, both of which reduce regeneration effectiveness and cause the P20BA fault code to be recorded.
  • Regeneration efficiency drops, and the P20BA signal is recorded if the fuel pressure is too low.
  • Low-Quality Fuel: If the fuel is of poor quality, soot generation will rise, causing the DPF to get blocked and the P20BA error code to be recorded.

Is P20ba Code Something to worry About? How Serious is it?

A P20ba error message may indicate a problem with the vehicle’s exhaust system.

When this occurs, it’s usually because of a problem with the engine’s exhaust gas recirculation (EGR) valve.

Because of this, hazardous emissions may rise, and engine efficiency may drop.

The stringency of this regulation is issue-specific. A loss in fuel efficiency and increased emissions might result from a faulty EGR valve.

A failed emissions test is a real possibility. This issue, if not fixed, may escalate into far more costly engine repairs if left unchecked.

How to Fix P20BA Error Code on 6.7L Powerstroke?

Code P20BA is a fuel pressure regulator issue on 6.7L Powerstroke engines. A new fuel pressure regulator will solve the problem.

  1. The negative wire must be disconnected to turn off the battery.
  2. Take apart the housing for the air filter.
  3. Remove the vacuum hose from the fuel pressure regulator.
  4. You need to remove the fuel pressure regulator from its bracket.
  5. swap out the old fuel pressure regulator with a new one.
  6. Replace the space hose that connects to the fuel gravity regulator.
  7. Fit the housing for the air filter.
  8. Get the negative cable back in the battery.
  9. Turn the key to see whether the fuel pressure is correct.
  10. Check for vacuum leaks or replace the fuel compression regulator if the fuel pressure exceeds the acceptable range.
  11. The last step is to remove the battery for a few minutes to clear the error messages.

Cost of Fixing P20ba Error Code

The cost to resolve a P20ba error code varies by automobile model and problem. Error code repairs might cost several hundred to several thousand dollars. The type of vehicle, code cause, and labor to replace components may affect cost.

Fixing the P20ba error code is usually cheaper than buying a new automobile. If the problem is simple, like a malfunctioning sensor or an easy-to-replace item, the fix may be a few hundred dollars.

If the problem is complicated and involves replacing important components like the catalytic converter or engine, the cost might escalate fast.

Take the automobile to a skilled technician for a diagnostic test to establish the P20ba repair cost. The technician can identify the problem and estimate repair prices.


The 6.7 Powerstroke is not the easiest engine to work on, but with experience and training, you can run it smoothly again in no time.

All 6.7 Powerstroke issues may be fixed with the correct components, equipment, and know-how.

In conclusion, the 6.7 Powerstroke is not the easiest engine to work on, but it can be repaired quickly and easily with the correct information and skills.
