All relevant symptoms, causing factors, and step-by-step solutions are discussed in detail, making it an invaluable resource for anyone encountering this issue. With the right information, this dreaded error code does not have to be a nightmare.
What Does P20BA Code 6.7 Powerstroke Mean?
When a Ford 6.7L engine displays the DTC (Diagnostic Trouble Code) P20BA, it means the PCM (Powertrain Control Module) has detected an anomaly in the voltage of reductant heater A. This component is located in the DEF (Diesel Exhaust Fluid) tank and aims to heat liquid exhaust from freezing. When this error code appears, it confirms that there is something wrong with reductant heater A and that the PCM cannot heat it due to unusual voltage levels.
Symptoms Of Getting The P20BA Code On A 6.7
This code may be present if certain symptoms are observed, such as difficulty starting the vehicle or stalling. It is important to take note of any peculiarities in the vehicle’s behavior, as they could indicate an underlying issue.
- CEL (Check Engine Light) is Turned On
- Sluggish Driving Experience
- Reduced Engine Power or Reduced MPG (Mileage Per Gallon)
- Excessive Smoke From Exhaust Panel
- Other SCR (Selective Catalytic Reduction) Related Codes
The Causing Factors Of The Error Code P20BA
The P20BA code 6.7 Powerstroke can be attributed to various possible causing factors. It is important to take steps to identify and rectify the underlying issue at hand. Common causes may include issues related to the vehicle’s hardware, electrical systems, or software components.
- Damaged Reductant Tank Heater A
- Shorted or Open Reductant Heater Harness
- Poor Electrical Connection Of Reductant Heater Circuit
- Failed Or Shorted Diesel Exhaust Fluid Supply Line
- Damaged Powertrain Control Module (Rare Scenario)
How Serious Is Code P20BA On 6.7 Powerstroke?
When a Ford 6.7L Powerstroke presents the DTC P20BA, it is imperative to address it to avoid damaging the engine further. Fortunately, ethical and unethical ways of solving this issue can be explored; therefore, do not despair if presented with this error code.
How To Solve P20BA Code 6.7 Powerstroke?
It is recommended to acquire the necessary equipment before troubleshooting the error code.
- 5.5 to 15mmm Socket, Extensions & Ratchet
- Safety Goggles
- Flashlight
- Gloves
The two solutions to the error code are replacing the DEF Tank or deleting the DEF emission system. It is important to note that if local regulations exist, deletion of the factory-installed DEF emission system should not be attempted.
Replace The Diesel Exhaust Fluid Tank
Replacing the DEF tank is necessary to address the issue with the heater part. This is due to the impossibility of purchasing and installing a replacement for only this component.
Taking the first step, one should begin by replacing the DEF Tank.
Step 1: The driver-side driveshaft requires two 13mm bolts to be removed from the front part of the skid plate down the center.
Step 2: The 13mm bolts in the truck’s rear must be removed. Located approximately two feet ahead of the rear differential, these bolts must be removed for further steps to be executed.
Step 3: The five fasteners on the rail side, situated on the driver’s side of the skid plate, must be removed. Additionally, other skid plates supporting bolts need to be taken out.
Step 4: The fuel door will be opened, and the three 5 ½ mm screws will be removed. After that, the DEF pillar neck cap is to be removed.
Step 5: Positioning the DEF pillar neck downwards and returning the cap to its rightful place will help avoid potential mishaps resulting from spills.
Step 6: The DTF tank’s connectors and injector hoses must be detached.
Step 7: The 13mm bolts supporting the DTF tank have been removed.
Step 8:Â Following the instructions, acquiring a new DTF Tank and ensuring proper installation is advised.
Delete/Manipulate The DEF Emission System [Danger Alert]
In states where strict emission control system rules are in place for vehicles such as the 6.7L truck engine, it is highly advised not to proceed with any modifications of the emission control system. However, in regions where this task is legal, an individual should seek assistance from a professional to modify the DEF emission system and remove the signal light. Attempting these tasks independently could be detrimental and should be avoided at all costs.
Common Mistakes While Solving The P20BA Code
It can save more than $150 by attempting the replacement job independently, but caution must be taken.
Avoiding common mistakes when resolving the error code P20BA will help ensure success.
- Not Getting Necessary Equipment While Doing The Operation
- Not Checking State Rules Before Deleting The Emission System
Additional Comments To Consider Regarding The P20BA Code
This diagnostic trouble code is a common issue for 6.7L systems, with users typically encountering it within the emission control warranty period of five years or 50,000 miles. After that point, any repairs needed due to this code can be costly – estimated at $500+, including labor costs. In most cases, the DEF tank needs replacing or the entire system deleted; the best action depends on the situation.
Final Words
This article aims to understand the P20BA code 6.7 Powerstroke comprehensively. With this knowledge, individuals should be able to identify and potentially rectify the issue independently. If desired, they can visit an auto shop for professional assistance. However, this may incur costs ranging from $80 to $150, depending upon the hourly labor rate.
