P0A06 OBD Error Code: Problem & Solutions

<<See All OBD Codes

When will the control circuit be low for the motor electronics coolant pump ‘A’? What does P0A06 error code tell you? What are its symptoms and diagnosis? This is a common type of error code which appears in the vehicle if the engine begins to overheat. If the motor electronics coolant pump doesn’t operate properly as desired, then the P0A06 error code will be stored.

The coolant pump of the hybrid system is known as the motor electronics coolant pump which is both operated and carefully noted by the powertrain control module. The power management-controlled ECU that is electronic control unit will find out that the coolant temperature is having high voltage with the help of coolant temperature sensor which in turn is already built in along with an inverter and converter assembly. The signal from the coolant temperature sensor is further used by the engine control unit to measure the efficiency of the inverter cooling system. The inverter output will be controlled by the engine control unit, if necessary, so that overheating of an inverter can be avoided to a certain extent.

What causes this problem with the Motor Electronics Coolant Pump 'A' Control Circuit Low?

• Defective motor electronics coolant pump 'A'.
• Motor electronics coolant pump 'A' harness might have an opening or short circuit.
• Motor electronics coolant pump 'A' circuit might have a weak electrical connection.

1. Electronic Control Unit - Are you looking to replace the damaged ECU? Find them at Parts Avatar at the best prices online.
2. Engine Coolant Temperature Sensor - The broken engine coolant temperature sensor has to be fixed so that the vehicle functions normally.
3. Variable Camshaft Timing Solenoid - Getting rid of the P0A06 error is easy if the contaminated VCT solenoid is instantly replaced.
4. Cylinder Head Gasket - Do you find the cylinder head gasket to be broken? Quickly replace them with new cylinder head gasket from Parts Avatar.
5. Powertrain Control Module - Do you find the powertrain control module to be defective? Find them at best prices from Parts Avatar.
6. Engine Wires - P0A06 error can be avoided if the damaged or corroded engine wires are replaced or fixed immediately.

If you are facing OBD error code P0A06, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Excessive heat by the engine.

It is very important to fix the fault code P0A06. So here are some ways with which you can correct this issue:

• Replacing the defective VCT solenoid.
• The damaged head gasket cylinder has to be changed.
• Changing the damaged PCM/ engine wires.

To do all this, you will need a few high-quality auto parts such as electronic control unit, coolant temperature sensor, VCT solenoid, cylinder head gasket, powertrain control module, engine wires and so on. From where will you get them? From your local store? Well, why go there when you can order quality parts with us while sitting in the comfort of your home. So, just browse through our website and order your needed parts today.

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

• This is a general type of error code, where the diagnosis process and the repair work are not difficult to execute.
• Whenever this error rises in your vehicle, it is always the best idea, to hand it over to the qualified or trained professionals.
• Whenever this error arises, the mechanic will use a scanner to check the trouble codes in the vehicle. But a trained professional will use an advanced scanner like Auto hex- to check with the advanced diagnostic process.
• The mechanic will also carefully check the wiring harness if they are broken, damaged or corroded. If they are defective replace them as quickly as possible.
• After checking the wires, the mechanic will look for possible damages with the VCT solenoid as it might get stuck or will be contaminated. If there are any damages, the VCT solenoid will be replaced.
• In order to carry out this diagnostic process, the engine must be in proper working condition, where there is no polluted air in the engine.
• As a very rare case, you will find the powertrain control module to be faulty which has to be replaced quickly.
• If there are any other error codes which are more or less like misfire condition, lean running, or polluted air entering the engine, they must be rectified first, before further proceeding with the P0A06 error code.
• After the diagnosis, it is good to always reset the code and the vehicle must be test driven to know if the issue is resolved. Test driving the vehicle will help the mechanic to know as to where the error occurred.

Common Mistakes When Diagnosing the P0A06 Code

• High voltage coolant pump faces some problem.
• Malfunctioning powertrain control module.
• Issues related to wires.
