Overview
Error Code: E SPN-FMI: E00013221
Possible Causes:
- Air Path Issue – Leakage between the air cleaner and compressor inlet.
- Installation Issue – Incorrect installation or reverse positioning of the air mass flow sensor.
- Electrical Issue – Malfunctioning components, including:
- Faulty intake manifold pressure sensor
- Faulty intake manifold temperature sensor
- Faulty air mass flow sensor
Effects of the Error:
- CE Lamp: Blinking or stays ON
- Torque Reduction: Severe (Level 2)
- Inducement Group 1 (EGR Block):
- If EGR is present, DPF regeneration is inhibited (both active and forced).
Component Location
The air mass flow sensor’s location varies based on the machine application.
Diagnostic Conditions
- Engine must be running.
Fault Code Trigger Conditions
The fault code is set when the measured air mass flow sensor value deviates beyond the acceptable threshold compared to the calculated airflow into the cylinder.
Fault Code Clearing Conditions
The fault code is cleared when the air mass flow sensor’s measured value returns within the acceptable range compared to the calculated airflow into the cylinder.
