    ON THE PICTURE, I CANNOT FIND THE VACUUM LINE FROM THE EGR SOLENOID TO THROTTLE BOX AND MY MONTERO SPORT DOES NOT HAVE A TURBO. MY EGR SOLENOID HAS TWO VACUUM LINE THAT CONNECT SOMEWHERE IN THE ENG.

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.
Below is a technical service bulletin I have located on your vehicle, It may or may not be related to your current problem. I simply wanted you to have it.

Code p0403 on a 2001 chrysler intrepid


Hi there:
P0403 - Exhaust Gas Recirculation Circuit Malfunction



The most common failure is the EGR solenoid goes bad. The code will not set and turn on the light until the car's computer has gotten around to completing the EGR self-test.

The P0403 indicates the computer is not seeing any voltage on the blue wire coming back from the egr solenoid.


With the ignition on and engine off, use a scan tool to activate the EGR solenoid. Listen or feel for a clicking, indicating that the solenoid is operating.

If the solenoid does operate, you'll have to check current draw on the ground circuit. It should be less than one amp. If it is then the problem is intermittent. If it isn't then there is excessive resistance in the circuit and perform the following

1. When it's activated see if you can blow lightly through it. IF you can\'t there may be a blockage causing excessive resistance. Replace EGR solenoid as needed. If there is no blockage, disconnect the EGR solenoid and the PCM connector containing the EGR solenoid control circuit. Using a digital Volt-Ohm meter (DVOM) check resistence between the control circuit and battery ground. It should be infinite. If it isn't, then there is a short to ground on the control circuit. Repair the short to ground and retest as needed.

2. If the solenoid doesn't click as it should, disconnect the EGR solenoid connector and connect a test light between the two wires. Using the scan tool, command the EGR solenoid on. The light should light up. If it does, replace the EGR solenoid. If it does not perform the following: a. Check for 12 Volts on the ignition supply voltage to the solenoid. If it isn't present, inspect the supply circuit for an open, or a short due to chafing or breakage and re-test. b. If it still doesn't operate: then manually ground the EGR solenoid control circuit. The light should light. If it does, repair open in EGR solenoid control circuit and re-test. If it doesn't, replace EGR solenoid.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Engine check lite comes on Code 401 Changed EGR valve and EGR Lite comes back on drive about 5 miles


Sounds like to me you have a faulty EGR vacuum solenoid which regulates the vacuum pressure sent to the EGR valve.

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.

Has code 403


P0403 - Exhaust Gas Recirculation Circuit Malfunction

The Exhaust Gas Recirculation (EGR) system is controlled by a vacuum solenoid. The solenoid is supplied ignition voltage. The Powertrain Control Module (PCM) controls the vacuum solenoid by grounding the control circuit(ground) or driver. The primary function of the driver is to supply ground for the object that is being controlled. Each driver has a fault circuit that the PCM monitors. When the PCM turns a component on, the control circuit voltage is low, or close to zero. When the component is turned off, the voltage on the control circuit is high, or near battery voltage. The PCM watches for these conditions, and if it doesn\'t see the proper voltage at the proper time, this code is set.

Potential Symptoms: Usually a fault in the control circuit, will leave no noticeable symptoms other than the Malfunction Indicator Lamp (MIL) illumination. However, if the EGR control solenoid is stuck open due to debris, etc. the code may be accompanied by misfire under acceleration, rough idle, or engine dying altogether.

Causes: The causes for a P0403 EGR code could be any of the following:
* Bad EGR solenoid
* Excessive resistance in control circuit (PCM controlled ground) due to an open, chafing or damage to the harness
* Poor connection at the EGR solenoid harness (worn or loose pins)
* Water intrusion at the EGR solenoid harness
* Blockage in EGR control solenoid holding solenoid open or closed causing excessive resistance
* Loss of supply voltage to EGR solenoid
* Bad PCM

Possible Solutions: With the ignition on and engine off, use a scan tool to activate the EGR solenoid. Listen or feel for a clicking, indicating that the solenoid is operating.

If the solenoid does operate, you'll have to check current draw on the ground circuit. It should be less than one amp. If it is then the problem is intermittent. If it isn't then there is excessive resistance in the circuit and perform the following

1. When it's activated see if you can blow lightly through it. IF you can\'t there may be a blockage causing excessive resistance. Replace EGR solenoid as needed. If there is no blockage, disconnect the EGR solenoid and the PCM connector containing the EGR solenoid control circuit. Using a digital Volt-Ohm meter (DVOM) check resistence between the control circuit and battery ground. It should be infinite. If it isn't, then there is a short to ground on the control circuit. Repair the short to ground and retest as needed.

2. If the solenoid doesn't click as it should, disconnect the EGR solenoid connector and connect a test light between the two wires. Using the scan tool, command the EGR solenoid on. The light should light up. If it does, replace the EGR solenoid. If it does not perform the following: a. Check for 12 Volts on the ignition supply voltage to the solenoid. If it isn't present, inspect the supply circuit for an open, or a short due to chafing or breakage and re-test. b. If it still doesn't operate: then manually ground the EGR solenoid control circuit. The light should light. If it does, repair open in EGR solenoid control circuit and re-test. If it doesn't, replace EGR solenoid.

Hope helps (remember to rate and comment this).

I need to know what the top EGR vaccum line runs to. the stem has broke and i don't know what to replace. It is a 2000 Mitsubishi Montero Sport with 3000 V6 4x4


i have a 99 montero sport just went and looked at it, my tube comes off and tees one tube goes to a metal tube on the top of the intake and the other goes to a little solenoid mounted by the throttle body. the solenoid is brown with a tip on the bottom where the tube connects.
