I need to calculate Intake Manifold Absolute Pressure from OBD Data. I have Toyota Corolla GLI 2010 Model. This car has MAF engine which does not return Intake Manifold Absolute Pressure. Where'as I got Intake Manifold Absolute Pressure from Honda Car Because Honda Car's engine was MAP Type.

Can Anybody Provide me the formula for calculating Intake Manifold Absolute Pressure using OBD data.

  • There is no such formula. Your best bet is to add in your own MAP sensor. – vini_i Feb 1 '17 at 10:51
  • or use a vacuum gauge since map is baro minus gauge vacuum. – Ben Feb 1 '17 at 11:33
  • I just want to calculate it for my Machine learning. I dont want to install a part in my vehicle. – Zeeshan Shakil Feb 2 '17 at 11:14
