The trouble code P053C can be explicated as Positive Crankcase Ventilation Heater Control Circuit High. It is the engine control module which would examine the positive crankcase ventilation heater control circuit. This trouble code would be set by the ECM when the positive crankcase ventilation heater control circuit voltage would not be as per the parameters set by the manufacturer. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

• Diagnosing the P053C fault code can be easy; all you will need is a diagnostic scanner, a digital volt/ohmmeter and a source of vehicle specific diagnostic information. You may use your source of vehicle information to locate a technical service bulletin (TSB) that matches the vehicle year, make, and model; as well as the engine size, code/s stored, and symptoms exhibited. If you find one, it could yield helpful diagnostic information.

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 Number 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 Number 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 carburettor 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.

Step 2

• Examine 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 P053C Code
