Hi my names john and I have a 1996 Ford ranger. Bought it with check engine light on, and have to get e-check soon. I looked up code P1405, and its a problem with a sensor. My friend has a ranger so I tried his sensor and tubes, but check engine light came on again. My friend says he thinks engine might be misfiring, and it does leak a little oil. So my code was P1405 and I was wondering if you guys could help thanks.
 
Basically means the sensor is reading atmospheric pressure or less at the upstream EGR test port.
