Guide To P02ED OBD Error Code Solutions

<<See All OBD Codes

Just like P02EC, OBD Error Code P02ED is a generic trouble code and mostly applies to all the OBD-II vehicles. In Spite of being generic the ways to diagnose and correct may vary from vehicle to vehicle. To have a deeper knowledge of OBD error code P02ED, you will have to go through our subsequent sections.

As most of us already know that the DIAFCS system also known as the Diesel Intake Air Flow Control System is bolted to your vehicle’s intake manifold in the intake air stream. This system is responsible to control the amount of incoming airflow. This OBD error code P02ED will be set by the PCM when there will be a detected low air flow condition in the diesel intake air flow control system.

What causes this problem with the Diesel Intake Air Flow Control Motor?

• Possible short to ground in the signal circuit to the DIAFCS motor/control
• Problems with the DIAFCS motor/control
• Possible open in the signal circuit to the DIAFCS motor
• Faulty Powertrain Control Module
• Voltage problems in the signal circuit to the DIAFCS motor/control

5. Throttle Body - You might need to undergo Throttle body replacement to fix this obd error code P02ED with your vehicle.

Have you ever wondered why is it so important to know the symptoms of the problem? Well, it is extremely essential to know the symptoms of the problem in order to detect it. Keeping this in mind, let’s throw some light on few common symptoms of OBD error code P02ED.

Common Symptoms

• Illumination of Electronic Throttle Control symbol
• Gradual Power Loss
• Illumination of the Malfunction Indicator Light
• Low Idling speed
• No Burning of Soot out of the DPF Catalyst
• Increased Fuel Consumption

After knowing the causes and the symptoms of the problem, next thing on your list should be to get rid of that problem, or in other words to correct that problem. Now, how will you solve this issue? Well it’s simple. All you need to do to correct this issue is to undergo the following replacements, such as

• Diesel intake air flow control motor
• Powertrain Control Module
• Throttle Body Assembly

In order to diagnose this OBD error code you will need an OBD-II scanner. Just like you diagnose any other error code you will need to reset the OBD-II code and conduct a road test. If the code returns, you will need to check the power and the ground to the sensor.

Firstly, you will need to locate and visually inspect your vehicle’s DIAFCS motor control system. Also, check the connectors and wirings to it. Make sure there are no scraps, bare wires, burnt spot or melted plastic. Next, take out the connectors and check carefully for any burns or green tints that indicate corrosion. Clean the terminals if needed. Next, use a scan tool to check if the OBD error code P02ED returns. In case it does you will need to inspect the DIAFSC and all the related circuits for any damage. Now, take the key off and disconnect the electrical connectors at the DIAFCS motor/control. Now connect a digital voltmeter black lead to the ground terminal at the DIAFCS motor/control wiring harness connector. Now turn the key on and engine off and check for the manufacturer’s specifications. Make sure that the voltmeter reads 12 volts. In case it does not, you will have to repair the power or ground wire. You can also replace the PCM if needed. While installing the PCM make sure it is programmed and calibrated to the vehicle correctly. Now, in case all tests pass and you still face the same code, then you will need to check the manufacturer specifications.

Common Mistakes While Diagnosing The P02ED Code

You might undergo the following failures:

• PCM failure
• Throttle body assembly failure
• Wiring issue
