P2074 code definition

Manifold Absolute Pressure/Mass Airflow - Throttle Position Correlation at Higher Load

What the P2074 code means

P2074 is an OBD-II generic code for the Engine Control Module (ECM) detecting a final mass airflow adaption stored value at a higher load (more than 15% above or below the calibrated threshold).

What causes the P2074 code?

  • Leaks or restriction in the air charge cooler or intake air hoses
  • Leaks or restrictions in the crankcase vent system
  • Damaged or defective mass airflow (MAF) sensor/inlet air temperature sensor
  • Biased mass airflow and inlet air temperature sensors

What are the symptoms of the P2074 code?

  • The Check Engine Light will be illuminated and the code set in ECM memory (the ECM may go into failure mode depending on manufacture strategy)

  • The engine may have limited acceleration, slow throttle response and RPM will be limited

  • The vehicle may not run smooth and stall or hesitate.

How does a mechanic diagnose the P2074 code?

  • Scans and documents the codes in the ECM

  • Looks at the freeze frame data for each code so the failure may be duplicated and repaired

  • Checks the entire intake system and mass airflow sensor for obstructions, loose or broken pipes and hoses

  • Performs the manufacturer pinpoint test on the mass airflow sensor to check for proper voltage signal and return signal

Common mistakes when diagnosing the P2074 code

  • Clearing ECM memory codes before checking the freeze frame data for the main failure problem

  • Failing to clear the ECM codes after the codes are fixed

  • Replacing the mass air flow sensor without duplicating the fault

How serious is the P2074 code?

Code P2074 is an indication that the ECM cannot detect how much air is getting into the engine, or the system has restrictions in the intake air supply that restricts the air when compared to the amount of throttle that is opening.

What repairs can fix the P2074 code?

Additional comments for consideration regarding the P2074 code

Code P2074 indicates a different than normal correlation between the throttle angle and the amount of air the mass airflow sensor senses is coming into the engine.

Mister Ron was very nice and took time out to explain any concerns I might have about my car. He also made sure he communicated with me when he was on his way, once he was outside, and when we was done working on my car. I appreciate that considering I have a newborn that I had to look after.
