What is the MAF sensor on a MaxxForce DT?
This article provides overall MAF sensor calibration information including how to record a MAF calibration for a MaxxForce DT, 9, or 10 snapshot for a case file and diagnostic steps for MAF calibration failures. The MAF calibration is used to measure the volume and density of air entering the engine at any given time.
What are the rules for MAF sensor diagnosis?
An incorrectly applied or faulty PCV valve can result in incorrect MAF data where the PCV intake through the breather hose is upstream of the MAF. So, the first two rules of MAF sensor diagnosis are: 1. Find and eliminate all external air or vacuum leaks downstream of the MAF sensor.
How to record a MAF recalibration in performance session?
Record a MAF recalibration in the performance session by selecting ’Procedures’ then the KOER ’MAF Sensor Calibration’. – Start calibration procedure. Then select ’Record”.

What should the MAF reading be at idle?
With the engine at idle, the MAF’s PID value should read anywhere from 2 to 7 grams/second (g/s) at idle and rise to between 15 to 25 g/s at 2500 rpm, depending on engine size. Most manufacturers provide specifications for air flow at idle; some will provide specifications at several engine speeds.
What happens if SPN 132 FMI 11 MAF sensor fails?
If SPN 132 FMI 11 – MAF sensor calibration failed – Insufficient number of data points sets, engine conditions are not stable to accept MAF calibration 1. Check to ensure entry conditions were all met (if EOT or ECT become lower than 176 F, test will fail) 2.
