Engine Emission Control

Note. Do not permanently remove or render inoperative any part of the vehicle emission control system including related hardware. Failure to comply may violate applicable state and federal laws.

Note. The vehicle emission vacuum routing diagrams are contained in the Description and Operation subsection of the Engine Emissions Control service information. Refer to EVAPORATIVE EMISSIONS SYSTEM article.

The engine emission control system consists of the

1. EGR system.
2. PCV system.

EGR System

The EGR system returns a small amount of exhaust gas into the intake manifold. This reduces the overall combustion temperature. Cooler combustion temperatures provide a significant reduction of the Nitrogen Oxides (NOx) in the exhaust emissions.

The engine incorporates a stepper motor-controlled EGR valve which receives its signal from the PCM. Engine coolant is used to cool the EGR valve. The EGR valve and stepper motor are serviced as an assembly.

The amount of recirculated exhaust gas depends on

1. engine rpm.
2. intake manifold vacuum.
3. exhaust backpressure.
4. Engine Coolant Temperature (ECT).
5. Throttle Position (TP).

PCV System

The PCV system uses intake manifold vacuum to ventilate blow-by vapors and evaporated oil from the crankcase and returns them to the intake manifold for combustion. The PCV valve varies the amount of blow-by vapors returned to the intake manifold based on available engine vacuum. The PCV valve also prevents the entry of combustion backfiring into the crankcase. The PCV valve is serviced as part of the crankcase vent oil separator.

2. Remove the Air Cleaner (ACL) outlet pipe. For additional information, refer to «INTAKE AIR DISTRIBUTION SYSTEM & INTAKE AIR FILTERING SYSTEM»(/ford/transit-connect/i-2009-2013/remont/removal-installation/#intake-air-distribution-system-intake-air-filtering-system) article.
3. Disconnect the 2 engine wiring harness electrical connectors and release them from the bracket.
4. Disconnect the center PCM electrical connector.
5. Disconnect the EGR valve electrical connector.
6. Release the clamp and remove the upper radiator hose from the coolant outlet adapter.
7. Release the clamp and remove the heater hose from the EGR valve.
8. Remove the 2 bolts and the EGR valve. Discard the gasket. To install, tighten to 20 Nm (177 lb-in).
9. Clean the mating surfaces of any residual gasket material.
10. To install, reverse the removal procedure. Install a new EGR valve gasket.
11. Fill and bleed the cooling system. For additional information, refer to «ENGINE COOLING SYSTEM»(/ford/transit-connect/i-2009-2013/remont/cooling-system-mechanical/#engine-cooling-system) article.
