I have two 74 1.8 pars cars (I know, its a sickness) both cars are beyond running, but the air flow sensor looks to be in great shape. I would like to verify that they are working and other than installing them on a running 1.8 how can I test them?
yes I plan to sell them, but I don't want to sell non working parts. Thanks |

Inside the AFM there is a fixed resistance, a variable resistance and a switch. With an ohm meter and a diagram these components can be tested. The switch should close when the flap is opened slightly and the resistance should vary smoothly. The Dr. pointed out the common mechanical failure. On the electrical side the usual failure is wear of the wiper components causing bucking or flat spots. If the black cover has been removed someone may have tried adjusting it and it may never be right again.
