Error Code P053A: What It Means & What To Do?

Here are some steps which you should follow in order to diagnose this fault code:

 

A good starting point is always a technical service bulletin search for your particular vehicle. Advanced diagnostic steps become very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately. We include basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your vehicle.

 

Basic Step 1

 

There are a number of methods which would help in inspecting if PCV valve is working in right manner or not. A person can easily decide which method would be easier. Just keep in mind that it is extremely essential that the car engine should be idling regardless of what method you use. Have a look at two methods which would help in inspecting if the valve is useful:

 

Method 1:

 

The PCV valve should be detached from the valve cover with the hose still intact and after that a finger should be carefully placed over the open end of the hose. Now if the valve is functioning in the right manner, then you might feel a strong suction sensation. Then you should try to shake the valve and if it is rattling, then it would mean that there is nothing that would block its pathway. But if no rattling sound is coming, then it would mean that it is malfunctioning.

 

Method 2:

 

The cap from the oil filler hole on the valve corner should be removed and then place a stiff piece of paper on top of the opening. Now if the valve is in good working order, then they should be sucked in place against the hole in seconds. If the valve is not working correctly, then there is no need to immediately search for a replacement. Instead of that you should try to clean it by utilizing some carburetor cleaner, sparingly, especially in areas with significant contamination. You should always verify the existing discoloration or some gummy deposits and then all of them should be removed. This would indicate that the valve is now properly cleaned up.

 

Basic Step 2

 

You must check the harness which is included in the PCV system circuit. The PCV systems are subject to oil present within the system, which can be the causes of the oil contamination. If there is a leakage of oil on the harnesses, wires and/or connectors then it would result in some electrical problems. This can be because the oil can and will overtime eat away at the important wire insulation. So, if you are noticing any such thing, then it should be repaired to ensure a great electrical connection within the positive crankcase ventilation heater control circuit.

 

Common Mistakes When Diagnosing The P053A Code

 

Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one doesn’t follow all the steps carefully. In this code usually people replace positive crankcase ventilation heater control without even properly diagnosing it.

 

The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.

Error Code P053A: Positive Crankcase Ventilation Heater Control Circuit/Open

Error Code P053A is defined as Positive Crankcase Ventilation Heater Control Circuit/Open.  Error Code P053A is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system, specifically those made since 1996 up to present. It commonly appears among BMW, Chrysler, Ford, Jeep, Mini, etc. Specifications on the definition, troubleshooting, and repairs, of course, can vary from one make and model to another.

To remove harmful emissions from the engine, engineers provide the engine system with a PCV (positive crankcase ventilation), a system designed to keep these said vapors from getting to the atmosphere. The vehicle is also able to do so using manifold vacuum, as the latter sucks vapors from the crankcase in the intake manifold. The crankcase vapors are lead through the combustion chambers, along with fuel and air mixture, to be burned. To control the circulation within this system, a PCV valve is provided – this is both the ventilation system for the crankcase and its pollution management device.

Since the 1960s, PCV has become a standard for vehicles, and are two basic types of PCV systems, which the open and closed systems. Both works similarly, however, since the closed system has been proven to be more effective (since 1968), it has become the more commonly used pollution control system.

With the help of heater system/element, PCV can remove moisture, which happens to play the biggest role in collecting contaminants within the engine. As the engine runs, it generates heat that will burn off most of the moisture in the system. When the engine cools down, however, condensation automatically starts. This is why oils are added with specific additives, which works by suspending the water molecule caused by moisture. In due time, however, this can exceed its capacity, as the water continues to corrode the metal parts of the engine that damages it to an extent.

The PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) controls and adjusts the PCV heater control circuit. Error Code P053A is registered when the PCM detects a general malfunction in the PCV heater control circuit, or if it’s indicating an open problem in the circuit.

Common Symptoms

As with other error codes, this code activates the Check Engine light and registers the code to the vehicle’s memory system. Other common symptoms include:

  • Engine misfire
  • Sludge in oil
  • Engine oil leak
  • Excessive oil consumption
  • Increase in fuel consumption
  • Failed PCV valve can also lead to noise such as a whistle, whine, or other moaning noise

Possible Causes

  • Stuck open PCV valve
  • Open or short in the wiring of PCV heater control circuit
  • Out of range condition in PCV heater control circuit
  • Oil contamination of electrical connector and harnesses, causing electrical connection issues
  • Contaminated inline PCV air filter (possibly internal)
  • Defective PCV heater

How to Check

As with most malfunctions codes, a TSB (Technical Service Bulletins) can help in troubleshooting P053A. Advanced diagnostic steps can be vehicle specific, and may require the right set of tools or skills to perform accurately. For this guide, we have included the basic steps that you can follow. However, it is best to refer to your TSB and look for the vehicle’s year, make, model, and powertrain for the specific diagnosis and repair guide.

Step 1

There are many ways to check the PCV valve, so you will have to decide which step is more convenient for you. Whatever the method you choose, make sure the engine is idling. Here are the two methods to diagnose the PCV.

First Method

With all the hose intact, disconnect the PCV valve from the valve cover. Then, carefully place your finger over the open end of the hose. If the valve is working properly, you will feel a strong suction. After this, shake the valve. If it rattles, that means there isn’t anything that obstructs the pathway. If it doesn’t rattle, however, it means it’s damaged.

Second Method

Take off the cap from the oil filler hole on the valve corner, then place a stiff piece of paper on top of the opening. The paper must be sucked in place against the hole in a matter of seconds if the valve is working properly.

However, if you find out that the valve is not working properly, it is important that you don’t jump into replacing it. Rather, try cleaning the valve using a carburetor cleaner, sparingly, especially in areas with great contamination. Verify any present discoloration and remove any gummy deposits, as this can be a good indicator that the valve is cleaned.

Second Step

Check the harness involved in the circuits of the PCV system. The PCV system is subjected to oil, which is why oil contamination can be a common cause of the problem.

For oil leaks on harness, connectors, and wires, oil leak can lead to electrical issues, as oil can cause wear to the wire insulation. If you see anything of this nature, make sure to do the necessary repair or replacement of the problematic connection within the PCV heater control circuit

Verify the harness involved in the PCV system’s circuit(s). Given the fact that the PCV systems are subject to oil present within the system, one of the possible causes is oil contamination. If oil is leaking on harnesses, wires, and connectors, this could cause electrical issues, because the oil can and will, over time, eat away at the important wire insulation. So, if you see anything of this nature, make sure to repair it adequately to ensure a good electrical connection within the positive crankcase ventilation heater control circuit.

How to Fix

Depending on the diagnosis, common repairs for this code include:

  • Replacement of the PCV valve
  • Thoroughly cleaning of the PCV valve using carburetor cleaner
  • Repair of oil leaks in the PCV heater control circuit
  • Repair or replacement of damaged connector, wire, and harness in PCV heater control circuit caused by oil contamination

As said earlier, this guide is for general information purposes only. It is best to refer to your TSB for the specific steps for both diagnosis and repair of this error code.
