Mass Air Flow - Low input
1998 Volvo S70
The car had problems starting, the fuel trim was reading -25%. MAF connector unplugged and the car ran fine. Replaced MAF sensor and fuel trim is way better now at 2%.
I keep getting the Low Input engine code. I checked the power cable from the connector and I have battery voltage. I checked the resistance on the 3 wires from the ECU to connector and they're all good. Also replaced air filter when MAF was replaced. Cleaned ECU connector and MAF connector with contact cleaner but the fault keeps coming back.
Any ideas?
