Filter Light On....again

[Oldtoad]

Filter light came on so I changed both air filters.
Light stayed on so checked connection to sensor, hoses, clamps, all good. Then the light went out, wha-la.
Did a full throttle run, filter light came on again...is it time to replace sensor???

It MIGHT be time to replace the sensor, assuming all connections are good. It might also be some kind of glitch with the computer. You might begin by attempting to determine exactly what the circuit is sensing. Is it some kind of flow related thing or a differential pressure sensor? Good luck on this one.

Thanks.
Sensor time.
