The engine emission control system consists of the

1. positive crankcase ventilation (PCV) system.
2. exhaust gas recirculation (EGR) system.

The EGR system returns a portion of the exhaust gas to the intake manifold to reduce the combustion temperature. This results in lower nitrous oxide formation.

The powertrain control module (PCM) controls the EGR vacuum regulator solenoid. The EGR vacuum regulator solenoid controls the vacuum to the EGR valve. When the EGR valve opens, exhaust gas flows to the intake manifold. The EGR transducer measures the flow through the EGR system module to exhaust manifold tube and sends a signal to the powertrain control module.

The PCV valve

1. controls the amount of ventilating air and blow-by gases going to the intake manifold.

The EGR system module-to-exhaust manifold tube

1. connects the exhaust manifold to the EGR valve.

The EGR system module transducer

1. monitors the EGR system module flow rate through the EGR-to-exhaust manifold tube.
2. sends an EGR system module flow rate signal to the powertrain control module.

The EGR vacuum regulator solenoid uses input from the PCM to change the EGR system module operation.

Scheme 2

1. Remove the 4 transaxle roll restrictor brace bolts. To install, clean the bolts using a wire brush, apply new threadlock to the threads and tighten to 55 Nm (41 lb-ft).
2. Remove the bolt and the transaxle roll restrictor brace. To install, clean the bolts using a wire brush, apply new threadlock to the threads and tighten to 48 Nm (35 lb-ft).
3. Disconnect the exhaust gas recirculation (EGR) system module vacuum tube and electrical connector.
4. Disconnect the EGR system module-to-EGR system module tube fitting. To install, tighten to 40 Nm (30 lb-ft).
5. Remove the 2 bolts and the EGR system module. To install, tighten to 25 Nm (18 lb-ft).
6. To install, reverse the removal procedure.

Removal and Installation

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to «JACKING & LIFTING»(/ford/five-hundred/i-2004-2007/remont/hoistjack/#jacking-lifting) .
2. Remove the 4 transaxle roll restrictor brace bolts. To install, clean the bolts using a wire brush, apply new threadlock to the threads and tighten to 55 Nm (41 lb-ft).
3. Remove the bolt and the transaxle roll restrictor brace. To install, clean the bolts using a wire brush, apply new threadlock to the threads and tighten to 48 Nm (35 lb-ft).
4. Disconnect the exhaust gas recirculation (EGR) system module-to-EGR system module tube fitting. To install, tighten to 40 Nm (30 lb-ft).
5. Disconnect the EGR system module tube-to-RH exhaust manifold fitting and remove the tube. To install, tighten to 40 Nm (30 lb-ft).
6. To install, reverse the removal procedure.

Scheme 4

1. Remove the 4 transaxle roll restrictor brace bolts. To install, clean the bolts using a wire brush, apply new threadlock to the threads and tighten to 55 Nm (41 lb-ft).
2. Remove the bolt and the transaxle roll restrictor brace. To install, clean the bolts using a wire brush, apply new threadlock to the threads and tighten to 48 Nm (35 lb-ft).
3. Disconnect the positive crankcase ventilation (PCV) valve tube from the PCV valve.
4. If equipped, disconnect the PCV valve electrical connector.
5. Rotate the PCV valve counterclockwise to remove from the valve cover.
6. To install, reverse the removal procedure.
