“E” SPNFMI:E00013219

Reasons:

1 Electrical problem (Air mass flow sensor connector)

2 Electrical problem (Wiring harness Air mass flow sensor to ECU, Faulty Air mass flow sensor)

3 Electrical problem (Faulty ECU, ECU connector)

 

Effect:

CE lamp ON Torque Reduction 1(Mild) Inducement Group1

(EGR Block) – with EGR only DPF regeneration inhibit by Active and Forced

 

2) Component Location

Air mass flow sensor location is dependent on machine application.

 

3) Condition for Running Diagnostic

Key on or engine running or Key off(ECU on)

4) Condition for Setting the Fault Code

If there is short circuit to battery OR open load on the Air mass flow signal line.

5) Condition for Clearing the Fault Code

Air mass flow signal value is in operation range

 

6 ) Check List

In the case of a sensor using a 5V supply, the ECU supplies power directly and consists of three supplies. Therefore, if a sensor related fault occurs, check whether sensor power supply problem

(SSpMon1 or SSpMon2 or SSpMon3 fault occurred together) and fixed them first.
