Error Code P2074: What It Means & What To Do?

<<See All OBD Codes

Is the Check Engine Light illuminated on the instrument panel of your car? Is your vehicle’s acceleration turning weak? If your answer is “YES” then there is a possibility that your vehicle is indicating a fault with the Maf sensor & throttle position correlation being high and this is diagnosed as an OBD P2074 error code. To know more about this error code P2074 and it’s few common causes and symptoms take a look at the sections below.

Are you wondering what this fault with the MAF and TPS sensor translates into? The powertrain control module (PCM) is responsible for controlling the amount of air flowing through the engine. PCM will set this error code P2074 when it detects a failed signal correlation between the Manifold Pressure (MAP) and Throttle Position Sensor (TPS).

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

• Air charge cooler or intake air hose leakage
• Leaking crankcase vent system
• Faulty air flow or MAF sensor
• Faulty inlet air temperature sensor
• Partial mass airflow and inlet air temperature sensors

1. Manifold Absolute Pressure Sensor - Also known as the key engine sensor is responsible for sensing the entire engine load, so you really can’t afford to have a defective one in your vehicle. Flashing OBD error code P2074? If your answer is yes, then without a doubt you will have to replace the faulty MAP sensor today.
2. Mass Air Flow Sensor - As we already know that this 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. Don’t think twice and replace the damaged ones today.
3. Throttle Position Sensor - A faulty throttle position sensor can lead to sudden idle surges and weak acceleration. If you are looking for a replacement for your vehicle, then all you need to do is to browse through our collection of TPS sensors and find the right one for your vehicle.
4. Powertrain Control Module - A faulty Power Control Module (PCM) can become irregular to an extent that your car will fail to start or will begin to stall while running. You will notice that exhaust fumes are shorted while the car is running and emissions system control indicators are decreasing. So having a PCM that isn’t working properly is not a good idea, you need to have it replaced right away to resolve the obd error code P2074.
5. Air Filter - OBD error code P2074 flashing? Clogged air filter? What are you waiting for? Replace the bad ones today with us.
6. Throttle Body - If you don’t already know this, we would love to tell you that it is responsible for managing the fluid flow for your vehicle. Any damage to the throttle body can result in the occurrence of OBD error P2074 code. Repair the damages or replace the throttle body by ordering online. It’s easy and you can avail free shipping on order above CAD $99.
7. Engine Control Module - You can’t afford to go a long way with your defective engine control module as it will lead no start condition or engine stalling. So, it’s definitely a good idea to replace the damaged ones today. Buy best priced engine control modules with us for all make and models.

It is vital 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 P2074 here:

Common Symptoms

• Flashing of check engine light
• Limited engine acceleration
• Weak throttle response
• Limited RPM
• Vehicle stalling or hesitation
• Rough engine running

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

Start your diagnosis for the error code P2074 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 P2074 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.
