I just ran the codes on my truck and its showing a low map sensor voltage. This is a brand new sensor. I checked the voltage going to the sensor and it is showing right at 5 volts which is what is normal. Is there any way to check the map sensor itself? I have checked the old one which I'm not sure was bad to start with and I can't get an ohm reading at all between any of the connector pins or between the pins and the body of the sensor. Should there be an ohm reading through the unit?

Regards,
