The EGR will not interfere with the starting of the van.
I would make sure the shifter is in Park (or neutral) and try again.

Jimmy has problems starting when its cold. the egr code popped can this cause a starting hesitation problem?


Yes the egr valve could cause starting problems. If it is sticking open it would cause a huge vac leak.
I would want to know what the trouble codes are in the computer first. Those codes would help a mechanic nail down the problem area and what to check.

Ford e150 codes: p0401, p1401 and p0174. read the more details to see what the symptoms are.


Stop, DO NOT replace expensive parts or O2 sensor! Ford Explorer codes p0174 , p0401 , rough idle and check engine light on. First thoroughly check all of the hoses and elbows connected to the intake and EGR (vacuum system) for splits, cracks, holes or tears, this could quickly cause these codes and fixes for less than $10. Check all connectors and the EGR valve sensor it could have a crack as well, inspect thoroughly because a split sensor could appear attached to the vacuum hoses but hoses could just be sitting there not actually attached due to a split or crack. This was my problem replaced the EGR valve sensor and the two little vacuum hoses attached to them for $50-60 with in stock parts at the local parts store. Took less than 10 minutes to replace and is easily accessible, the check engine light turned off immediately without having to reset the codes by disconnecting the battery, idle became normal and fuel efficiency better. If you have THOROUGHLY inspected every hose, connector and elbow and found no issues, clean the MAF with electrical contact cleaner ( let dry) and clean the EGR with carbon cleaner. A dirty MAF or EGR could also cause these codes to pop up. If this still doesn't work, then consider replacing the EGR, if that isn't it then try the O2 sensor. Good luck!

I HAVE A CHRYSLER 300, V-6, AND THE ENGINE LIGHT IS ON , AND IT SMOKES WHEN I START IT UP. WHAT MAY BE THE PROBLEM? IS IT THE EGR VALVE?


EGR Valve failures are pretty rare. It's really unlikely that your EGR valve has anything to do with your engine smoking. The smoke is more likely to be caused by bad valve seals worn piston rings, a leaking injector, a leaking fuel pressure regulator, or a blown head gasket. The Check Engine Light being on is anybody's guess until you ask your engine computer why it turned the light on. Who knows? There might even be a fault code in there that may lead you to the cause of the smoking problem.

How do I replace the EGR valve in my 1999 Ford E350 van?


Your vehicle has an EGR valve attached to the intake manifold. About how to replace an EGR Valve, check this procedure...
Parts:
1. EGR Valve

Tools:
1. Scan Tool
2. 3/8 in. Drive Ratchet
3. Wrench
4. Socket Set

Steps:
Step 1 Locate the OBD-I or OBD-II data link connector (DLC). Refer to your vehicle owner’s manual for the specific location.
o Tip: The OBD-I data link connector is usually located in the engine compartment near the battery or the fuse box. The OBD-II connector (post 1995 cars) is usually located beneath the instument panel next to the steering column.

Step 2 Turn your key to the“ON” position. Do not start the engine.

Step 3 Plug your scan tool into the DLC and follow the manufacturer's steps to read the diagnostic trouble code. Codes between P0400-P0408 are generic trouble codes for the EGR system.
o Tip: The OBD-II diagnostic trouble code (DTC) is a 5 character alphanumeric code. The first digit is a letter that indicates the component group, the second digit is OBD mandated or manufacturer specfic, the third digit is a subgroup, and the fourth and fifth digits define the component and basic problem.

Step 4 To test the EGR valve: Remove the vacuum line to the valve and install a manual vacuum pump. Start the engine and apply vacuum to the valve. If the engine idle speed drops, the EGR valve is working. If the engine idle speed does not change, the EGR system is not working. Most engines will stall if you fully open the EGR valve while idling.
o Tip: Some vehicles are equipped with electronically controlled EGR valves. Use a scan tool to test these valves.

Step 5 Remove the vacuum line or electrical connector from the EGR valve.

Step 6 Remove the EGR mounting bolts. Remove the EGR valve.

Step 7 Using a new gasket, attach the new EGR valve with the original mounting bolts. Torque the bolts to the manufacturer's specifications.

Step 8 Reconnect the vacuum line or electrical connector.

Step 9 Erase any codes on the scan tool through the“delete” or“erase” command. Remove the scan tool.

Step 10 Road test your vehicle to verify the repair.
o Tip: If the check engine light returns, repeat the diagnostic process for additional DTCs or take your vehicle to a certified repair shop.

Check the RIGHT PART before to take off the parts. Its possible that you can find few TSB in your library or dealer about this LINK.

Hope helps.

Engine light came on in my dodge caravan sxt 3.3L 6cyl. Code P0404. It seems to be running fine, how do I check the EGR valve myself? Any advice would be greatly appreciated.


To check the egr yourself you will need a hand held vacuum pump. To perform the test start the van and let it warm-up, then remove the top vacuum hose from egr valve and attach hand vacuum pump to egr valve. Apply about 5 in-hg vacuum to the egr valve. With the engine at idle speed and vacuum applyed the engine idle speed will drop or stall. If not then the egr valve is faulty and will need to be replaced. If the engine didi change idle speed and or stalled the egr valve is good. Hope this will help you.

How to remove and inspect throttle body on 1992 mazda miata


Things that make your engine do what it is doing.

1. Vacuum leak
2. EGR valve

Find the vacuum leak if there is one.. and check the function of your EGR valve.

A functioning EGR valve with an ORAL vacuum line suction test will cause the engine to stall / die when suction is applied to the ORAL external line.

Even if it passes the ORAL test... it can still have carbon build inside the plumbing that does not allow the seating pin to fully seat and the engine will surge or be hard to start when warm.

So check / listen carefully for vacuum leaks and check the EGR valve.

Check engine light ?


sometimes when the gas cap gets left off, it sets a code and turns on the check engine light. if the problem returns, it very well could be the egr valve....they tend to have a build up of carbon in the valve and can stick open.this problem can cause a rough idle, hesitation and stalling. you can remove the valve and use a screwdriver , with a torx bit i think, and turn the inside of the valve to break up the carbon deposits...should fix it, but with no code its hard to tell exactly what the problem is.
