Locating my EGR solenoid on my 95 S10 4cyl

My 95 S10 cyl has a massive vacuum leak caused by the old hard lines cracking. I'm replacing the lines; however, I can't seem to get a clear picture on where my EGR solenoid is located. The valve is rather obvious so I can get plenty of ppl who think they know what they are talking about telling me how to find that. I also don't need to hear, "in the intake manifold" one more time unless you would like to tear that bad boy apart once more for me and point it out. Please and thank you!

It is located between the EGR valve and the intake vacuum source, one line gores to a vacuum port on the intake and the other to the EGR valve, just follow the lines.

SOURCE: Difficulty to replace EGR valve in 1999 totyota camry 4-cyl automatic

If you have small hands it can be easy. The space between firewall and EGR is tight but it wasn't too difficult to remove. The vacuum hose at the bottom was hard to pull off and I ended up cracking it and had to splice it. It was more difficult to re-install the EGR then remove it. I had a difficult time with keeping the gasket aligned while bolting it in to the lower tube. I took a few attempts. I suggest when replacing the EGR leave the mounting bolts loose so you can more easily align the metal tube. I would tighten the metal tube at the bottom of EGR first then tighten the upper two mounting bolts on top. It took me about 5 minutes to remove and 15 minutes to replace. I would be sure to clean the IAC too after cleaning the EGR. I sprayed throttle bottle cleaner down the bottom hole located on the throttle body and let soak about 15 minutes then start and run the engine a minute and repeat the process. This helped smooth the idle while stopped at a light. It also stopped the idle from shaking and almost stalling the car out at a traffic stop when the engine was warm.

SOURCE: no vacuum to egr valve

there is an EGR vacuum solenoid somwhere that controls on/off vacuum to actuate the valve. i am not to sure of the location, but follow the vacuum line back from the egr until you find a device that looks like an electrical check valve for vacuum. that is a possibilty. but then again i am a ford,chrysler guy and am just giving you an answer based on my understanding of the functuality of a vacuum egr system

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.

Vacuum leak often causes surging. At the age your truck is, vacuum hoses are a likely problem check for cracking and such. Replace as needed.

It shows code P0401. Already replaced the EGR valve and catalytic converter plus sensors. What now.


You didn't say if you have any symptoms so I will assume you don't. After you made the repairs, you have to have the code removed. Any major auto parts store will do it for free. If the code don't come back, its fixed.

What controls the opening and closing of the EGR solenoid?


ECU controls the EGR system. Check for vacuum to the valve with the engine running. There should be no vacuum. If you have vacuum disconnect the electrical to the vacuum control solenoid and see if the vacuum goes away. If it does you have a command or wiring problem and will need to trace the signal wire back to the ECU.

My egr valve keeps cracking


What you should know is the EGR valve is an Extended Warranty part under Federal Pollution guidelines. While the mileage and age of your vehicle may have exceeded the Warranty period of the original Factory part, there are some guarantees on the replacement part depending on the brand.

That said, it is The EGR that is the victim rather than the cause of your problem. Overheating of the EGR is the likely cause of the cracking. The EGR is not apparently opening fully or at all.

This is a problem. Because the onboard computer should be monitoring the various switches that control the opening and closing of the EGR valve.

I would suggest having the passages to the EGR valve cleaned. Have the Vacuum lines to the EGR valve checked for routing between switches. Incorrect routing of the Vacuum lines can also cause poor acceleration.

Smoking, EGR valve failure, etc can be a clogged Exhaust system too!

Before buying another EGR see if you are eligible for a free replacement.

Have a compression test done to verify engine health and replace the sparkplugs at that time.

Please comment on my info.

2002 Windstar starts fine but when I shift gear the engine shut down, any idea what's cause?


I would think it may be either the idle speed control solenoid located on the intake manifold or an open Vacuum line part.

There is some rerouting of Vacuum force to different Vacuum lines when you shift into gear. Some of the Pollution parts(EGR), the transmission shift solenoids may be Vacuum operated, so when the defective part receives Vacuum force, it leaks out and stalls the motor.

One of the old tricks is to get an old spray bottle and fill it with water. While the engine is running, mist the intake seams and the Vacuum lines. If there is a leak, it will change the RPM or stall the engine. Once you find it, fix it.

The idle speed control solenoid is embedded in the intake manifold. Go online to an autoparts site and look up the part. You can see a photo or the part and know what you are looking for or go to an autoparts store and see the part.

I hope my solution is helpful. Please rate my soluton.

If you have a manifold leak that will cause a MASSIVE vacuum leak and make it run rough at idle only. Look at your short term fuel trims with a scanner, if they are way negative you have a vacuum leak. Fix the intake manifold leak and that will fix your problem.

P400 code on a 2000 mitsubishi diamante


P0400 - Exhaust Gas Recirculation Flow Malfunction
The exhaust gas recirculation (EGR) valve is vacuum controlled valve that regulates the amount of exhaust gases that re-enter the cylinders. The powertrain control module (PCM) determines how much based on engine load, temp, and other conditions. If the PCM detects that the amount of exhaust gases entering the cylinder were insufficient or non-existent, this code is set.

Symptoms: No symptoms will likely be noticed by the driver other than the MIL (malfunction indicator lamp). However, non visible symptoms will be increased combustion temperature and increased Nox emissions.

Causes: A code P0400 may mean that one or more of the following has happened:
Plugged EGR passage which restricts the flow of exhaust gasses
Faulty EGR solenoid
Faulty EGR solenoid wiring/harness
Vacuum lines damaged/disconnected to the EGR valve solenoid or to the EGR valve
Faulty EGR valve

Possible Solutions: Since EGR valve designs are different, no one test will suffice:
Using a scan tool, operate the EGR valve with the engine running. If the engine stumbles, the problem was likely intermittent wiring problem or intermittent blockage problem
If engine doesn't stumble, operate the EGR valve manually, if possible. If engine doesn't stumble and die, the ports are likely plugged. Removal of valve and cleaning of all ports will be required
Checking of solenoid can only usually be done with a scan tool, because most solenoids operate with a duty cycle of voltage, rather than constant voltage
Check all vacuum lines, hoses, etc for any damage
Visually inspect the solenoid harness and the solenoid for damage
Replace EGR valve

Hope this helps.

The purge solenoid should be in the hard plastic vent lines that run under the tube between the intake and the air filter, ablove the transmission, it is common for vibration holes to be worn in the hard plastic tubes causing a vacuum leak. The purge solenoid is small and it has an electric wire coming from it. I 'think' your canister is in the front lower left corner under the hood, you may have to remove splash shields to see it. The problem is most likely in the hard plastic lines at the solenoid. Let me know if this helps.

How do you replace the egr valve in a 1997 chrysler concorde lx


Chrysler Concorde 1993-1997 3.5L MFI 6cyl
Exhaust Gas Recirculation System
Operation

This system reduces the amount of oxides of nitrogen (NO x ) in the exhaust by allowing a predetermined amount of exhaust gases to recirculate and dilute the incoming fuel/air mixture. The diluted air/fuel mixture reduces peak flame temperature during combustion, which in turn inhibits the production of Nitrogen oxides. The principal components of the system are:
- EGR tube (connects a passage in the intake manifold to the exhaust manifold)
- EGR valve
- Electronic EGR Transducer
- Vacuum hoses


Component and System Testing
  1. Check the condition of all of the EGR system hoses and tubes for leaks, hardening or kinks on the rubber hoses. Repair and correct these conditions before proceeding any testing.
  2. Be sure that the hoses at both of the EGR valve and EGR valve control are connected to the proper fittings.
  3. Be sure the electrical connector is firmly attached at the valve control.
  4. To check the EGR system operation, connect the DRB III scan tool or equivalent to the 16-way data link connector. The data link connector is located on the lower edge of the instrument panel near the steering column. Follow the scan tool instructions.
  5. After checking the system with the DRB III scan tool, proceed to the EGR valve leak and control tests, then repair as necessary.

Loosen, but do not remove, the EGR tube to intake manifold screws

The EGR valve attaches to the rear of the right cylinder head.
  1. Remove the vacuum tube from the electric EGR transducer solenoid. Inspect the vacuum lines for cracking, poor seal due to hardness, or other problems. Replace with new hoses if necessary.
  2. Remove the electrical connector from the solenoid.
  3. Slide the transducer up and out of the mounting bracket.
  4. Loosen, but do not remove, the EGR tube to the intake manifold screws.
  5. Remove the EGR tube lower screws at the valve.
  6. Remove the EGR valve and transducer.
  7. Clean both gasket surfaces and check for any signs of leakage or cracks. Replace the components if any such damage is found or if the valve fails the tests.

To install:
  1. Loosely install the EGR valve and a new gasket onto the cylinder head.
  2. Using a new gasket, attach the EGR tube to the valve and tighten the screws to 95 inch lbs. (11 Nm).
  3. Tighten the EGR tube to the intake manifold plenum screws to 16 ft. lbs. (22 Nm).
  4. Tighten the EGR valve to the cylinder head screws to 16 ft. lbs. (22 Nm).
  5. Reconnect the transducer solenoid to the vacuum fitting on the manifold.
  6. Slide the transducer into the bracket.
  7. Reconnect the vacuum lines and electrical wires to the EGR transducer.
