P0403 P403 EGR valve solenoid pictoral reference
« Thread Started on Aug 24, 2010, 5:19pm »

I'm an active member of another automobile community which has comprehensive guides to anything and everything that could go wrong, so when I couldn't find such a guide here when I had what seemed to be a common problem, I got a little bit frustrated. In that frustration, I decided to create such a guide for the problem I was experiencing.

At 160k miles, my 2000 3.0L 2WD Montero Sport popped up a Service Engine Soon (SES) / Check Engine Light (CEL).

OBD II scan revealed two '403' codes:
P0403
[image]

And P0403 *pending*
[image]

The reading I had done on this forum suggested the fix was to replace the EGR Vacuum Solenoid.

Tools:
10mm socket with extension
Ratchet
Drill (Optional for convenience)

Work involved:
Remove engine cover:

Remove solenoid bracket (4 bolts)
[image]

At this point, you'll need to remove the vacuum hose from the upper solenoid port in order to lift out the bracket. It's right on top and easily reached/removed.

Remove the solenoid from the bracket (1 nut)
(Note the location of the 4 bracket mounting holes)
[image]

Detach the lower vacuum hose and the electrical connector. The connector is a "pinch and pull" type. Dont squeeze too hard or you may snap the plastic. My connector was firmly on the solenoid and took some wiggling.

Here is the solenoid, removed:
[image]

The replacement solenoid came from NAPA. They had one in stock at the local distribution hub. (Called them at lunch, they had the part by the time I got off work) The part number is 600-5434, and it is listed as "EGR Control Solenoid". List price was 39.99. I got it for 34.00 as a discount for being an active duty service member.

Finally, a picture of the two solenoids side-by-side:
[image]

The replacement process is precisely the opposite of the removal process. Make sure you get all the nuts/bolts snug, and don't forget to put the ground wire back on the upper passenger's side bracket mounting bolt if it was there to start with!

I'm not a fan of 'clearing' codes until they've cleared themselves, so the SES/CEL is still on. I have a different '99 car, and the CEL goes off after about 50 miles if the problem goes away. When/If the light goes off, I will update this thread.

Happy problem solving!

Good write up, this should be added to the "DIY" section of the website.

Quick Update. The *pending* code P0403 has self-cleared. All good so far!!

Great writeup! I'm having surging issues (EGR, or Solenoid). I'll try the solenoid first. Thanks a bunch for everything, especially the p/n.
-Note to others: Please include part numbers, brands etc when replacing anything. By his receipt, I see that he has a 2000 MS 3.0...this will help find the exact part for the exact same problem much easier.

I just got this part today. Napa had it, but went to the stealership since they had it in stock and I wouldn't have to wait a day (yea, I know, but we needed the truck). Anyhow, the price was within $2, so I didn't mind. Here is my receipt. I installed it and hopefully all will be well. I had the stealership check, and he said the p/n's for the 2000 MS 3.0 V-6 and mine (1998, same eng.) match perfectly. If you want the napa part, the number 600-5434 is okay, but translates to a newer p/n (9100 something ), but either way they can find it. So far, the repair seems to have worked..

Well the repair did prevent the vehicle from shutting off at stop signs, but the surging is still present. I tried all of the fixes mentioned above and still no cure. I'm taking it to the stealership this tuesday. I know they are pricey but I am tired of messing with it and just need it fixed asap.

I know this is an old post, but I have done the EGR solenoid valve replacement as described above and still have the SES light coming back after two-three restarts even when I clear the code.

Does the vehicle need to be driven?

What voltages am I looking for at the solenoid connectors?

Thanks,
wrench

@Wrench What fault code is present, if its 403 then you have a circuit malfunction check the wiring. you can manually check the egr function by pinching the yellow striped vac. hose leading to the throttle body with engine idling this will cause the EGR valve to open if it does then the valve and vac. system is good. You are looking for a ground and 12v at the connector with engine running. you can check the solenoid function by supplying it with 12v and ground and listen for a click.
