Hi,

The P0403 code represents a problem with the Exhaust Gas Recirculation Solenoid or circuit.Below is the chart that explains and directs us to where the problem may exist.

Since there are a number of components or wires that can be at fault for this code,I feel it is not going to be something that we should attempt to diagnose via long distance. You may wish to check the basic wiring and vacuum supply to the solenoid, but if you find that the ECM is at fault, you will want to have this type of problem backed up by a good part and labor warranty.
Most solenoids need about 20 ohms or slightly higher resistance on the primary winding circuits to function correctly.

  1. Using the VACUUM HOSE ROUTING as a guide, check to be sure that the vacuum hoses are correctly connected.
  2. Check the connection condition of the vacuum hoses, (removed, loose, etc.) and check to be sure that there are no bends or damage.
Be sure to clear any trouble codes after you have made any repairs to the system.

What is fault code po403 on my grand cherokee


Code 403 is a problem with the EGR valve.
You'll need to get the flow chart to run the tests for that code to find the problem. I would suggest a shop manual.

00 Camry 2.2 egr problem po 401 low flow new egr valve new solenoid new transducer new map clean passages. I don't know what else to do


Here is an overview for the code as it relates to Toyota cars.
I would go back and make sure the tubes and pipes are clear.
In most cases, the passage is plugged up, or the sensor does not "see" the flow.

Possible causes
- EGR passage clogged
- Faulty EGR Vacuum Modulator Valve
- Faulty EGR Valve
- Faulty EGR solenoid valve
- EGR solenoid valve harness is open or shorted
- EGR solenoid valve circuit poor electrical connection
- Dead (Weak) battery
- Faulty EGR temperature sensor and circuit
- Exhaust gas leaks

How to clean a egr valve from a 2000 mitsubishi montero. I replace the egr valve, but still engine ligth code 403 still on.


Your new EGR valve (assuming it wasn't defective out of the box), is fine, but the car's computer just needs to have its code 403 cleared. Even though you've corrected the problem, the computer will still light the "Check Engine" light, and store code 403 until the code is cleared using an OBD-II (On-Board Diagnostics 2) code scanner.
Note that the car will function perfectly with its new EGR valve, a lit "Check Engine" light and a code 403 stored. Its just a good idea to clear the code, so that then only NEW problems will become the reason that the "Check Engine" light gets lit.

Code number po 403


code P0403 EGR ( exhaust gas recirculation ) valve solenoid malfunction, could be many things most likely would be just a bad control solenoid but could be the wiring to the solenoid, but most likely is not a bad EGR valve.

Po401 ive cleaned the egr & replaced the egr but i keep getting this code??


depending on your model, there may be a solenoid valve that turns the vacuum to the egr valve on. If the solenoid fails, the egr valve will not open. Follow the vacuum line on the egr valve--does it go to a solenoid valve? If yes, apply 12 volts directly to the solenoid blades to see if it clicks open. If it doesn't click, replace the solenoid.

Egr valve cleaning


Usually the EGR valve problems show the fault code P0400 - Exhaust Gas Recirculation Flow Malfunction

What does that mean?
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
