I have an engine light that won't seem to go away. I put a code detector on it and got this code, which says it's an "exhaust pressure sensor". Can anyone tell me about this sensor? Location and what it does?
Thanks, Bert

What engine is in this truck?
Gas or diesel?


Below is for a gas engine
Check the EGR to make sure it is working. Also check the hose going to the EGR to be sure it is not broken or plugged up.
For the diesel
about the same check the egr tube to see if it is plugged up

The ebp sensor tube is prone to plugging up. You'll find it on the driver side, coming from the exhaust manifold (front) up to a sensor. Unplug the sensor, unscrew it, then run a wire down through the tube to clear it.

Thank You! So far no engine light. The tube wasn't plugged as much as the sensor itself. Thanks again.
