Guide To P2073 OBD Error Code Solutions

<<See All OBD Codes

If you are facing very weak acceleration and fuel efficiency with your vehicle chances are that your vehicle is set to obd error code P2073 or related codes likes P2074. These codes are generic OBD-II error codes that indicate a problem of your vehicle’s manifold absolute pressure or mass air flow - throttle position correlation at idle.

Your vehicle’s PCM also known as the powertrain control module is i charge of monitoring the throttle position with the mass air flow readings to make sure they are within the specifications. It will set this error code P2073 whenever it detects that the expected readings and the actual readings vary to a large extent. To know more about this error code and few of its common causes take a look at the section below.

What causes this problem with the Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Idle?

• Faulty or defective or damaged MAF or mass air flow sensor
• The throttle position sensor might be damaged
• There might be damaged wiring and connectors related to the MAF responsible for this error code
• A dirty air filters
• Faulty PCM (Powertrain Control Module)
• A vacuum leakage between the air cleaner box & throttle body

1. Manifold Absolute Pressure Sensor - Believe us or not, but you can’t really go a long way with a faulty manifold absolute pressure sensor because it is the key sensor that senses the entire engine load. So, don't think twice and replace the damaged ones with new ones today.
2. Mass Air Flow Sensor - It is one of the key components of an electronic fuel injection system in your car, and you can’t go a long way the defective ones. Without giving a second thought, replace the damaged ones today.
3. Throttle Position Sensor - Sudden idle surges and weak acceleration? All of this indicates towards a faulty throttle position sensor and results in flashing of error code P2073. If you really wish to get rid of this error code P2073, then replace the damaged ones today at PartsAvatar.
4. Powertrain Control Module - Also abbreviated as PCM is an integral control unit. So a defective one should be changed immediately replaced to avoid any further damage. If you need one for your car, you can easily find with us for your specific car make and model.
5. Air Filter - A dirty or clogged air filter can prove to be very harmful to your vehicle’s health. We recommend you to change the dirty ones at earliest to avoid any further damage to your vehicle.
6. Throttle Body - Damaged throttle body? Faults in fluid management of your vehicle? Flashing of OBD error code P2073? Well, then what are your waiting for? Replace the damaged ones today with us at PartsAvatar

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2073 here:

Common Symptoms

• Low acceleration
• Fall in fuel economy
• Flashing of check engine light

Here are some ways with the help of which you will be able to correct the OBD Code P2073:

• Firstly, undergo manifold absolute pressure sensor replacement
• After that undergo mass air flow sensor replacement
• Now, you must also undergo the faulty throttle position sensor replacement
• Make sure that you repair the vacuum leak
• Clean or replace the dirty air filter with a new one
• Repair or replace all the defective MAF sensor wiring and connectors

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade Manifold Absolute Pressure Sensor, Mass Air Flow Sensor, Throttle Position Sensor, Pcm, Air Filter, Throttle Body, Engine Light and a lot more for our precious customers.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2073 code to be stored:

• You will have to start your diagnosis for the error code P2073 by checking for all the wirings and connectors associated with the manifold absolute pressure and mass air flow sensors for any faults or damages
• After that you will need to inspect the sensors to make sure that they are operating properly as per the manufacturer’s specifications and procedures.
• Also inspect the throttle position sensor to make sure it is in proper alignment and is working properly.
• Also make sure that there exists no vacuum leaks and the air filter is clean.
• Last but not the least, you must make sure that the powertrain control modules is functioning as desired.

Common Mistakes When Diagnosing the P2073 Code

Talking about misdiagnosis, the most obvious misdiagnosis that you are likely to commit is to replace the manifold absolute pressure sensor and the mass air flow sensor without being sure of them being at fault. }
