Error Code P02E7: What It Means & What To Do?

<<See All OBD Codes

The OBD code can be described as diesel intake air flow position sensor circuit range/performance. The volume of air which is going through the intake is controlled by the intake airflow control valve on the throttle body. The intake air flow position sensor would tell the engine control module the position of the diesel intake airflow control valve. If a problem is detected by the engine control module with this sensor or the circuit for the sensor, then the P02E7 fault code would start appearing.

Want to learn something more about this fault code? The diesel intake air flow position sensor is generally bolted to the throttle body mounted to the intake manifold or in a tube which is present in the intake air stream. The DIAFPS sensor would convert the incoming airflow volume into an electrical signal for the powertrain control module.

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.

What causes this problem with the Diesel Intake Air Flow Position Sensor Circuit Range/Performance?

• The diesel intake air flow position sensor circuit might have poor electrical connection
• Faults in the throttle body assembly
• The diesel intake air flow position sensor might be defective
• Harness of diesel intake air flow position sensor might be opened or shorted
• Engine control module can start malfunctioning

1. Air Intake System - Did your mechanic just found out that there is some fault in the Air Intake System? Buy top notch Air Intake System from us at economical prices.
2. Mass Air Flow Sensor - A damaged Mass Air Flow Sensor can cause a lot of issues. It would be nice if you get it replaced on time.
3. Engine Control Module - Everything is fine with the Intake Air System and still OBD code P02E7 flashing? Then there is definitely some fault with the Engine Control Module. Get it checked and replace if needed.
4. EGR Valve Gasket - EGR Valve Gasket is an important car part which should never be neglected. May be there is some fault in it due to which P02E7 code may start flashing.
5. Powertrain Control Module - A faulty Powertrain Control Module can be troublesome. You can always rely on us as we have best auto parts for our customers.
6. Throttle Body - P02E7 code does not really end up spoiling your Powertrain Control Module, but it might also accompany few Throttle Body issues. We have best Throttle Body related parts with us
   

We care for our customers and that’s why we can totally understand your problem. That’s the reason why we have listed out some major symptoms behind the flashing up of OBD Code P02E7. They are mentioned here as follows:

Common Symptoms

• Issues in the indicator light on
• No regeneration of the diesel particulate filter to burn off the soot build up
• Low idle speed
• There might be No EGR system operation
• Issue of loss of power.

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P02E7:

• The malfunctioning air intake system should always be replaced
• The engine control module should be repaired or replaced
• Replace the EGR valve gasket
• Make sure that you replace the throttle body
• You can always replace defective powertrain control module

Now are you thinking that from where will you purchase these car parts? You have arrived at the right place. We at Parts Avatar care for our customers, that’s why we provide best quality of k&n cold air intake, fuel pressure regulator, mass air flow sensor cleaner at marketable prices.

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

If you find out that the P02E7 code is returning once again, then you must test the DIAFPS sensor and as well as the circuits which are associated with it. With the Key Off, you must disconnect the electrical connector at the DIAFPS sensor. Connect a digital voltmeter black lead to the ground terminal at the DIAFPS sensor wiring harness connector.

Connect the red lead of the digital voltmeter to the signal terminal at the DIAFPS sensor wiring harness connector. Turn Key On engine off. The manufacturer’s specifications should be checked; voltmeter should read 5 volts. If not, then you must repair the signal or ground wire or the powertrain control module should be replaced

Common Mistakes When Diagnosing The P02E7 Code

• Throttle body assembly failure
• Quirky wiring
• There can be some powertrain control module
