Hello and welcome to Just Answer! I would be more than happy to assist you today.
The exhaust gas pressure sensor is used to measure exhaust gas pressure in the exhaust manifold. This information is used by the ECM to control emissions and EGR valve operation.
The exhaust gas pressure sensor is located above the front section of exhaust manifold and is plumbed into the exhaust manifold between the number 1 and number 2 cylinders
Possible causes for this fault code include:
Exhaust Gas Pressure Sensor Circuit - shorted low. Low signal voltage detected at exhaust gas pressure circuit.
Your talking about exhaust gas pressure sensor. Then why does the computer in the truck say this?

Their is no sensor where you said. But there is a pressure tube that goes to a block where I assume is the sensor you are talking about. Their are three wires going to the sensor, but theirs only two prongs on the sensor. The plugin is cracked so it got moisture in it. So I was wondering if maybe one of the prongs corroded of the sensor?
Thanks a lot,
I replaced sensor and corroded connecters. Code is gone.
