Egr valve on tucson where is it


There is NO EGR valve/system on the 2005 Tucson. This particuar powertrain uses the CVVT (Continuous Variable Valve Timing) system which eliminated the need for EGR.

Go to www.hmaservice.com and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, illustrations and procedures, etc.

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 on


Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

1996 Mercury Sable with a 3.0L Duratec engine. My scanner shows a PO401 (EGR insufficient flow detected)code. I cleaned the EGR valve and replaced the gaskets but the code still shows up. What is the...


Before replacing anything else, it's important to clear the code before determining any more repairs are necessary. You can take the car to an autoparts store that features free diagnostic tests or you can disconnect the negative battery cable for 10 minutes to clear it. If after clearing the code P0401 still appears, then it comes down to 1 of 2 problems:
  1. Replace the DPFE sensor
  2. Replace the EGR valve
An illustration of both are found at the link below:
http://www.chiltonlibrary.com/content/images/9117/images/91174p58.gif

The DPFE is located at #1
The EGR is #2
Best of luck with your Sable.

Service engine light comes on the code is 32 have any idea


DTC code 32 is the EGR valve failure, check the vacuum hose and electrical connection to the EGR. remove the EGR and clean it with carb cleaner. After reinstalling the EGR and if the check engine light still on, you may have to replace the EGR valve. Good luck and hope this helps, keep me posted. Be glad to help.

the EGR valve is clogged on the backpressure port, that is the small tube that you need to clean the EGR valve needs to be replaced unless you are sure that air can pass through with the egr valve opened.
The engine light needs to be reset it does not automatically turn off. In some cases if the egr valve is known to be good as well as the modulator there may be a problem with the vacuum switching valve(VSV) that controls the egr system and this vsv may need to be replaced.

Code P1400 on a 1997 nissan maxima. help car wont pass inspection


P1400 on your vehicle is described as :Differential Pressure Feedback EGR Circuit Low Input You either need a new DPFE valve, or a new EGR valve. Both can be tested for functionality before replacing them both. EGR valve is more likely I think. Cleaning it may not improve its performance, but its worth a try. Also check the vacuum lines between the DPFE and EGR system. The EGR valve and DPFE are usually close together above the exhaust manifold/downpipe. you need service instructions to test these items, suggest you go to a garage really...
