P006A MAP/MAF Correlation failure Focus 1.0


Recommended Posts



I have read almost all of the solutions of other people who have problems with p006a faults in the forum. My car is 2012 model Focus 1.0

This fault occurred after ECU and Catalytic converter failure.

Purchased second hand ECU and reinstalled original software. The software has been discarded by the authorized service.

The original catalytic converter was assembled. Bosch brand MAP sensor was replaced with the old one. The air filter has been changed.

The original brand MAF sensor has been replaced with the old one. Tried by replacing the EGR Solenoid valve.

Air leakage control in the air suction line was done twice with smoke test. No leakage was observed with smoke.

However, it still continues to give the p006a error.

I'm open to any ideas that can help.
