SOURCE: Location of EGR Valve

Found the info!!

This Dodge EGR valve is a certain kind of device that is mounted right on your intake manifold which controls the amount of exhaust gasses back into your engine.
On a 2005 Dakota with 4.7 liter engine (non-HO), the EGR valve is located near the intake manifold on the driver's side right up against the firewall. It's hard to spot as it sits lower than the intake manifold. To change it, remove the electrical connector. There's a red tab that needs to be pushed to one side and then you have to squeeze down on a tab to get it free. Using a 13 mm socket, remove the bolt that you can see. I had to use a 3 inch wobble extention and then a 8 inch extension with a deep well socket to reach it with my 3/8 inch ratchet. There's a second bolt that you can't see between the EGR valve and the firewall. With a little trial and error and a lot more luck, you can reach the hidden bolt with the 3 inch wobble extension and a 13 mm deep well socket. Attach the ratchet after the socket is on and remove. This one isn't easy and if there's any Dodge engineers reading this one, a couple of extra inches of clearance between the valve and the firewall wouldn't have killed you no matter what the cost accountants said. With both bolts removed, you should be able to pull out the metal pipe that connects the manifold to the EGR valve out of the manifold (Pull to the right) and then you can lift the valve out. For assembly, the metal pipe connecting the intake manifold the EGR valve has to be removed and reinstalled on the new valve. It's held on with 2 5/16th" bolts. You should put the rear bolt on tight, but leave the front bold loose for the reinstall as some adjustment is necessary to get it put back together and the rear is a pain to tighten when installed. Line up the bolts that attach the valve and get the rear 13 mm bolt (The one you couldn't see on disassembly) started. Do not start the other 13 mm bolt as you'll need to pivot the valve and pipe to the left in order to reinsert the pipe into the intake manifold. Once the pipe is in the intake manifold. Start the other 13 mm bolt and tighten both 13 mm bolts and then the 5/16" bolts holding the pipe onto the valve. Reinstall the electrical connection. Please don't forget to rate!!!!

There is a system that monitors how well your egr system is working and it is saying that it is not. The egr valve is just one small part of that system. The plumbing could be plugged or the monitoring sensor, if it has one could be bad. I'll check into this a little further and get back.

SOURCE: EGR Solenoid creates no vacuum

The EGR solenoid is located towards the rear of the car from the EGR vavle and slightly towards the center. It kind of stands on end. There is a vacuum line coming out the top (port C) and a green 2 wire connector plugged into it. Hope this helps.

SOURCE: egr valve location on dodge ram 2005 4.7

The EGR, or exhaust gas recirculation valve, takes inert exhaust gasses drawn from the exhaust system and reintroduces them into the combustion chamber through the intake manifold. This process lowers the peak combustion temperature and helps combat the formation of Nitrous Oxide (NOx) in the exhaust.

  1. Separate the intake ducts from the air cleaner assembly by loosening the retaining clamps and pulling the ducts away from the housing.
  2. Disconnect the vacuum line from the air cleaner assembly.
  3. Remove the wing nut that secures the air cleaner housing lid to the base.
  4. Remove both the air cleaner hosing lid and base.
  5. Locate the EGR valve. Look at the front of intake manifold. The EGR valve will be bolted to the intake manifold just in front of the carburetor.
I hope help you with this. Good luck.

Where is the egr valve on a citizen c5


  • First you want to open up the hood of your car
  • Find the engine diagram sticker on the inside of the open hood and identify the mechanism that is labeled "EGR Solenoid" on the sticker.
  • Find the "vacuum line" on the sticker diagram and identify its color. This is the line that runs from the EGR solenoid to the EGR valve.
  • Locate the vacuum line inside the engine compartment of the vehicle toward the front of the driver's side. The vacuum line will be the same color on the vehicle as it is on the diagram.
  • Follow the vacuum line from the front of the vehicle where it connects to the EGR solenoid through the conduit that carries it to the EGR valve at the rear of the engine compartment. The easiest way is to track the uniquely colored vacuum line along the path between its two connection points. The vacuum line connects to the EGR valve, which is the disk-shaped object located at the rear of the engine compartment
    on the driver's side.

Code p0403


EGR is the exhaust gas recirculating valve . It's part of the emission system designed to lower emission of nitrates of oxygen. The vehicles PCM is sensing a problem with the flow or lack of flow thru the EGR valve. The EGR system has several components including the egr valve, erg solenoid, possible EGR temperature sensor and/or a DPFE ( differential pressure feedback sensor) and vacuum hoses. They are located on or near the intake manifold and connects to the exhaust manifold system also.

Need to find and replace the DPFE-15 sensor. Dealership diagnosed when service engine light came on and saaid this is what needed replacing. Problem is I do not know where to find it on the engine.


Exhaust Gas Recirculation (EGR) System The exhaust gas recirculation (EGR) system is designed to:
  • reintroduce exhaust gas into the combustion cycle.
  • lower combustion temperatures.
  • reduce the formation of oxides or nitrogen (NOX).
The amount of exhaust gas reintroduced and the timing of the cycle varies by calibration. Timing and volume are controlled by the following:
  • engine rpm
  • engine vacuum
  • exhaust system back pressure
  • engine coolant temperature
  • air charge temperature
  • throttle position
The EGR valve (EGR valve) (9D475) is vacuum-actuated. The vacuum hose routing diagram is shown on the Vehicle Emission Control Information (VECI) decal. The EGR system is a differential pressure feedback EGR Sensor system. Differential pressure feedback EGR Sensor is a subsonic closed loop EGR system. The differential pressure feedback EGR system:
  • monitors EGR flow rate by the pressure drop across the metering orifice located in the EGR tube.
  • uses a differential pressure feedback EGR sensor as the feedback device.
  • uses the EGR valve only as a pressure regulator, rather than a flow metering device.
  • controlled pressure is varied by the valve movement using vacuum output of the EGR vacuum regulator solenoid (9J459).
  • allows for a more accurate assessment of EGR flow requirements.

1996 PCED OBDII-Villager SECTION 1B: Description and Operation
Exhaust Gas Recirculation System
Exhaust Gas Recirculation (EGR) System Operation The exhaust gas recirculation (EGR) system (Figure 1 below) recirculates a portion of the exhaust gases into the intake manifold under average vehicle driving conditions to reduce combustion temperatures and exhaust gas NOx content. The amount of exhaust gas recirculated varies according to operating conditions and will be cut completely under:
  • Engine starting condition
  • Low engine coolant temperature condition
  • Excessively high engine coolant temperature condition
  • Engine idling condition
  • High engine speed condition
  • Mass air flow sensor failure
The exhaust gas recirculation (EGR) system on the Villager uses the exhaust gas recirculation/evaporative emission (EGR/EVAP) control solenoid valve to provide vacuum to both the EGR valve and the EVAP canister when commanded by the PCM. If the exhaust backpressure is sufficient to close the EGR backpressure transducer valve, vacuum is sent to the EGR valve and allows EGR gas to flow into the intake manifold. If the exhaust backpressure is not sufficient, the EGR backpressure transducer will remain open and allow vacuum from the EGR/EVAP control solenoid to vent to the atmosphere.
The EGR system monitor, for OBD II regulations, uses an EGR temperature sensor to monitor the EGR system. The EGR temperature sensor is a thermister located in the EGR passageway. When hot exhaust gas is recirculated into the engine, the temperature at the EGR passageway increases. This increase is sensed by the EGR temperature sensor and a signal is sent to the PCM to indicate EGR flow. If the EGR temperature sensor does not detect EGR flow when commanded by the PCM after two consecutive drive cycles, the malfunction indicator lamp (MIL) will be illuminated and a diagnostic trouble code (DTC) will be stored. The MIL will be turned off after three consecutive drive cycles are completed with no malfunctions detected. The DTC will remain stored in the PCM memory until 80 drive cycles have been completed without the same malfunction detected in the system.

Exhaust Gas Recirculation (EGR) Backpressure Transducer Valve The exhaust gas recirculation (EGR) backpressure transducer valve is used to control EGR. The EGR valve is operated by ported vacuum, but the ported vacuum will normally be vented off at the EGR backpressure transducer valve. As rpm increases, exhaust pressure increases and pushes on the diaphragm in the EGR backpressure transducer valve and closes the vacuum vent.
Figure 2: EGR Backpressure Transducer Value
Item Number Description 1 — Throttle Valve 2 — Vacuum Port 3 9D475 EGR Valve 4 9F452 EGR Backpressure Transducer Valve 5 — EVAP Canister 6 — EGR/EVAP Control Solenoid 7 — Vent
EGR/EVAP Control Solenoid The exhaust gas recirculation/evaporative emission (EGR/EVAP) control solenoid (Figure 3) is controlled by the powertrain control module (PCM). The EGR/EVAP control solenoid controls vacuum to both the exhaust gas recirculation (EGR) valve and to the evaporative (EVAP) emission canister. When the EGR/EVAP control solenoid is off (12 V signal from the PCM) vacuum is supplied to both the EGR valve and to the EVAP canister. When the EGR/EVAP control solenoid is on (ground supplied by PCM) vacuum is vented to the atmosphere keeping the EGR valve closed and no vacuum to the EVAP canister. The PCM will command the EGR/EVAP control solenoid on at:
  • Engine starting condition
  • Low engine coolant temperature condition
  • Excessively high engine coolant temperature condition
  • Engine idling condition
  • High engine speed condition
  • Mass air flow sensor failure
Figure 3: Exhaust Gas Recirculation/Evaporative Emission (EGR/EVAP) Control Solenoid
Exhaust Gas Recirculation (EGR) Temperature Sensor
The exhaust gas recirculation (EGR) temperature sensor (Figure 4) is a thermister type sensor that monitors the temperature of the exhaust in the EGR passageway. As the EGR flow increases, the temperature increases. This process creates a change in the resistance of the sensor, which decreases as the temperature increases. The signal is sent to the powertrain control module (PCM) to indicate that the EGR system is working properly. If the EGR temperature sensor does not change resistance as the PCM expects on two consecutive drives, the malfunction indicator lamp (MIL) will be illuminated and a diagnostic trouble code (DTC) will be stored.
Figure 4: EGR Temperature Sensor Exhaust Gas Recirculation (EGR) Valve
The exhaust gas recirculation (EGR) valve (Figure 5) recirculates portions of the exhaust gas back into the intake manifold to reduce the amount of the NOx released during combustion and to reduce combustion temperature. The amount of exhaust gases that are released into the engine is proportional to the load on the engine.

You need a charcoal canister and vent control valve.

You also need the EGR solenoid valve (I think it the brown one).

Valve is located in the valley of the V, towards the transmission side of engine.

Do these 1st and reset light. You may have other issues but you have to start here.
