Aoa Guys!
I am recently facing ‘the check engine light’ on my daihatsu mira Es 2013. The code ‘P0400 Exhaust Gas Recirculation (EGR) function failure’ is showing as per scanner. This code had been removed by the device twice but the check engine light appeared in the very next day.
i got my Egr valve cleaned, didn’t worked for me. I also replaced it with the other Egr valve but unfortunately this didn’t worked too.
My car has been tuned up properly i.e throttle body, cat and all. I have also checked the wiring too, they’re also working perfect. It’s been 4 days i am tracing the exact fault but nothing is working for me.
