How do you replace a egr back pressure transducer hose on a 1999 Mercury Villager?

To replace the EGR back pressure transducer hose on a 1999 Mercury Villager, first, locate the transducer, which is typically mounted on the engine near the EGR valve. Disconnect the old hose from both the transducer and the intake manifold or EGR valve, ensuring there's no debris in the ports. Install the new hose, making sure it fits securely at both ends, and then reconnect any other components you may have removed. Finally, start the engine and check for leaks to ensure the installation was successful.
