P20BA is one of the Diagnostic Trouble Codes (DTCs) associated with the Ford 6.7L engine. By definition, this code indicates a problem with Reductant Heater A Control Circuit Performance. When triggered by an error in the reductant heater circuit, the P20BA DTC will be stored and illuminate a warning light on the instrument cluster to alert drivers to possible malfunction in their vehicle’s emission control system.

This error code indicates that the PCM (Powertrain Control Module) has detected an unusual voltage of the reductant heater marked as ‘A.’ It is important to note that there are three heaters (A, B, and C), and it requires knowledge and experience to identify which one is A. Analyzing each heater’s voltage can help determine which one marks A; however, if uncertain, a technician should be consulted.

The reductant heater A is located in the DEF tank and works with the Powertrain Control Module (PCM) to prevent the diesel exhaust fluid from freezing. This system ensures that all engine components work together efficiently and safely. The reductant heater A is vital in keeping vehicles running correctly by protecting against possible damage related to frozen fluids.

When the error code appears, it alerts the user to a potential issue with the DEF tank heater. The Powertrain Control Module (PCM) cannot heat the tank due to an unusual voltage being detected. This could mean something is wrong with the heater itself or its connection, and a professional should look at it as soon as possible.

The Ford 6.7L Powerstroke is known for being a reliable engine, but when it throws the error code P20BA, it is one of the worst DTCs this model can receive. Ignoring this code will likely result in extensive damage to the engine and should not be taken lightly; immediate attention should be paid to ensure the proper functioning of the vehicle.

Don has the code covered and suggests following the next segment to understand ethical and unethical methods of solving error code P20BA. He further emphasizes that understanding what is ethically right and wrong will help effectively troubleshoot errors like these.

Before proceeding to solve the error code, it is advisable to equip oneself with the necessary tools and safety equipment:

  1. 5.5 to 15mmm Socket, Extensions & Ratchet
  2. Safety Goggles
  3. Flashlight
  4. Gloves

Once prepared, one can solve the error code in two ways: Replacing the DEF Tank or Deleting the DEF emission system.

The factory-installed DEF emission system must never be deleted or removed, particularly in states where such laws exist. This should be made clear to all concerned, and any attempts to do so may result in severe legal consequences. The importance of maintaining this system lies in its ability to reduce pollution levels and keep the environment safe for everyone.

Replacing the DEF Tank is the only solution to a problem with the heater part, as it cannot be purchased and returned separately. Here is a step-by-step guide on how to do so:

  1. Remove two 13mm bolts of the front part of the skid plate down the center from driver side driveshaft
  2. Remove the other two 13mm bolts of the back strap from the rear of the truck, about two feet ahead of the rear differential
  3. Remove five fasteners on the rail side driver’s side skid plate and supporting bolts
  4. Open the fuel door and remove three 5 ½ mm screws; remove the cap of the DEF pillar neck.
  5. Pull the DEF pillar neck down and replace the cap
  6. Detach connectors & injector hoses from the DTF tank
  7. Remove all 13mm bolts supporting the DTF tank
  8. Replace with new DTF Tank following prior steps

When considering an emissions control system for a 6.7L truck engine, one should first check the rules and regulations in their state to determine if any strict emission control laws are in place. If such laws exist, it is highly discouraged that this task be attempted as it may be illegal.

It is essential to ensure that modifying vehicles’ emission control system is permissible in one’s state. If it is, then a professional can modify the DEF emission system and eliminate the signal light. It is recommended to have someone certified and experienced complete this task rather than attempting oneself, as safety and efficiency are key considerations when making these modifications.

The P20BA code is one of the most common diagnostic trouble codes for 6.7L engines. Depending on the situation, technicians may need to replace the DEF tank or delete the entire system. Professionals must be adequately trained in this specialized area and follow all safety protocols when performing these repairs.

Most users have reported that the error code occurs within their emission control warranty period of five years or 50k miles. This warranty protects users should they receive this error code during its validity. However, after the expiration of the warranty period, it would become a costly case as it is estimated to cost at least $500 plus labor costs to diagnose and repair any associated issues properly.

She hopes that this article has been a helpful guide to understanding the DTC P20BA. With this knowledge, one should be able to identify and potentially fix their error code independently. If one feels uncomfortable attempting the repair themselves, they can take the vehicle to an auto shop for assistance. Depending on labor costs, repairs may cost between $80-USD 150.

FAQs About P20ba Code 6.7 Powerstroke

What causes the P20BA code?

When a diagnostic trouble code (DTC) P20BA is detected, the powertrain control module (PCM) has determined that the voltage signal from the control circuit of the designated reductant heater “A” is not within an acceptable range. This DTC indicates a performance issue and requires further investigation to identify and resolve any underlying problem.

What is the code P20BB on a 6.7 Powerstroke?

This particular trouble code indicates that the engine control module (ECM) monitors a low voltage within the reductant heater A control circuit. The associated consequence of this issue can be reduced power, increased fuel consumption, and overall decreased performance levels. It is essential to address this issue as soon as possible to prevent further damage or loss of efficiency.

What is code P20B9 on Ford 6.7 diesel?

When code P20B9 is displayed, it denotes no detectable voltage in the control circuit of the reductant heater designated as “A.” This distinction is made when multiple reductant heaters are used. Reductant heaters form part of a system designed to reduce diesel engine emissions.

What is a reductant heater assembly?

This reductant heater and sender assembly level sensor features four stainless steel electrodes, three arranged vertically to provide high, middle, and low-level signals. The fourth electrode runs the length of the level sensor and functions as a ground. Additionally, it is well-suited for use with reductants due to its electrical conductivity.
