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

<<See All OBD Codes

The trouble code P053A can be described as Positive Crankcase Ventilation Heater Control Circuit /Open. The positive crankcase ventilation heater control circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the actual positive crankcase ventilation heater control circuit voltage would not be as per the specifications set by the manufacturer.

Don’t worry if P053A error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. This would also give rise to the illumination of the check engine light.

What causes this problem with the Positive Crankcase Ventilation Heater Control Circuit /Open?

• Defective engine control module
• PCV valve that fixed unlocked
• Wiring problems might cause an open/short/out of range condition in the positive crankcase ventilation heater control circuit
• Malfunctioning PCV heater
• Polluted inline PCV air filter
• Electrical connection problem can be caused due to oil contamination on electrical connector or harnesses

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.
