Good morning! I have a Renault Trafic year 2005 Engine G9U 2500cc with 99Kw TD.

I replaced the air mass meter, now the DTC is no longer there but the performance is unchanged, it has no power, if I unplug the plug, however, the performance improves considerably, the connector of the meter had all the pins oxidised, I replaced them all but if I do the test with the multimeter I find ground, positive +12, positive + 5 but no signal with voltage variation.

can you send me a diagram or procedure for verification?

thank you greetings Raphael
