skid 1 Posted September 13, 2015 How can you check the sensor or wiring? I have no reading on my MFA, nothing at all! No dashes nothing! could it be my MFA is fault. The sensor is plugged in, and it's not plugged into the wrong plug either. Thanks for any info. Quote Share this post Link to post Share on other sites
fendervg 32 Posted September 14, 2015 Check the wiring continuity to the sensor with a multi-meter. Also you could try taking it out and putting it in hot water or somewhere warm and see if the resistance across the pins on it changes (this is assuming it has two wires to it, it's been a while since I've had mine off). It would be the same principle as testing a thermostat or coolant sensor. Hopefully it's not the dash unit that's at fault. Quote Share this post Link to post Share on other sites
