SOURCE: I got the code p0400 1.

first take the egr valve off then get some carb cleaner spray it into the egr valve ports let sit 30-60min then take a small flat head clean any carbon left over in it. then check the vaccume lines to it they to might be plugged you can take a small wire or push pin and stick it in the ports to unplug it.

That sounds like a lot. The part should be only $50 or so. Check with some other repair shops.

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: Where is the EGR Valve located on a 2004 Galant

It is on the firewall just behind the engine, to replace it you need to detach the vacuum hose, remove the two EGR valve mounting bolts, remove the EGR valve from the intake manifold and then put in the new one.

I have a p0400diagnostic code egr. what dose this mean I've just bought the manual but I cant find it ford focus 06


P0400 - Exhaust Gas Recirculation (EGR) Flow Description: The electric EGR (EEGR) system is monitored once per drive cycle during steady state conditions above 77 km/h (48 mph). The test fails when a concern is detected by powertrain control module (PCM) calculations indicating the EGR flow is less or greater than expected. Possible Causes:
  • EEGR valve stuck open or closed
  • Connector to EEGR not seated
  • EEGR motor winding circuits short or open
  • No voltage to the EEGR
  • Harness open or shorted to voltage or ground
  • Vacuum signal to manifold absolute pressure (MAP) restricted or leaking
  • Mass air flow (MAF) sensor signal erroneous
  • Carbon build up in the EEGR valve seat area
  • One or more sensors is not responding or is out of range
Diagnostic Aids: All of the following sensors input data to the PCM for correct operation of the EEGR system: engine coolant temperature (ECT), crankshaft position (CKP), intake air temperature (IAT), MAF, throttle position (TP), MAP. Any DTC relating to these sensors must be resolved prior to addressing code P0400. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test KD .

99 maxima ran till it was parked now it turns over will not start gave code p0400 any ideas


The fault is somewhere around the EGR valve - probably the EGR valve or the throttle position sensor.

Before replacing any sensors try removing and cleaning the EGR.

I have a 1998 Nissan Maxima GLE, I Failed the Emission Inspection (DTC) Diagnostic Trouble Codes of "P1492","P1105" What these Codes exactly? mean


A code P0300 may mean that one or more of the following has happened:
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective compute
  • P1105MAP/BARO Pressure Switch Solenoid Valve
  • Check and clean the MAP sensor, or replace.
  • P1492EVAP Canister Purge Control/Solenoid Valve (Circuit)
  • Replacing the purge solenoid will clear code P1492 This should also clear code P0300 as well.

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.

97 oldsmobile sihouette error code p0400. Was told by Advance auto it was a bad egr canister solenoid. Replaced it but still have check engine light on. How do I get it off?


After you have made the repairs go back to Advance Auto and have them remove this stored trouble code .Most places will remove them from your computer for free.

SEL code P0401 (2004 Mitsubishi Galant 2.4L)


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.

Code p0400 keeps coming up after changing the egr valve and sol.


It may be that the passage to the exhaust is blocked also.

Truble code p0400


the passage that causes this low flow is in the intake, it gets full of carbon and gunk, try running a wire through it, also make sure the EGR passes a functional test.
