The car will not reset changed the EGR. Changed the EGR vacuum switch. No lights on, no codes. Cleaned the tube for the EGR. Need to get it reset to take smog test.

Hi Mike,

I don't understand the issue. Did the Smog Test Station get an EGR code? Did they say there was a "functional test" issue? What was the reason for changing the parts?

Mitsubishi has revised the drive cycle for the EGR on those at least 3 times because they are hard to set. The current version is attached, in short you need the engine warmed up (coolant over 180), it has to be warmer than 45 degrees, and the car in drive. You then drive up to 40 MPH for at least 90 seconds, let off and coast down to 15 mph, once it drops below 15 accelerate back up to 40 for 20-30 seconds. Stop the car and shut it off. Restart it and repeat the above again. Check to be sure it is now set as ready.

Hi Mike,

Did what Steve found work? Haven't heard from you, so making sure you made it through the emissions test.

Just driving around won't set it. Have you tried the process they say to use and it still hasn't set? Or have you just driven it?

Driving in the back roads and driving like they say drive 38 MPH and down to 10 MPH and also went to 55 MPH down to 10 MPH still nothing. Think I might have to change the ECU.

I don't think it's the ECU, absent other codes I don't think the EGR parts are the issue either. Which state are you in? I want to look up your states inspection rules, most allow for one unset monitor. You have no lights on but they work with the bulb test correct? Did you use an OEM Mistu EGR or other?

Try this full drive cycle. This one should run all the tests.

A. Begin from Cold Start. Ensure your fuel tank is between 1/4 and 3/4 full. Engine coolant temperature must be below 122 F and within 11 F of the ambient air temperature with all accessories off.

B. Idle. Run engine for 2 1/2 minutes. Put the vehicle is Drive while holding the brake pedal, and hold for 15 seconds. Put the vehicle in Park and turn the ignition to OFF position. Repeat this step once.

C. Start the vehicle and begin to drive. Apply half throttle until 55 MPH is reached.

D. Hold your speed steady at 55 MPH for five minutes. Coast down to 10 mph do not brake.

E. Accelerate again at 3/4 throttle until 55-60 MPH is reached. Hold steady at 55-60 for 2 minutes. Coast down to 10 MPH do not brake.

Repeat this process 2 times. Not in the same day as you need to start with a cold engine both times. Now see if all the monitors have set.

Okay, try that drive cycle and see if it works. As I said the Mitsubishis are some of the hardest ones to get all the monitors set on. Almost as bad as EVAP on some BMWs.
On your 2003 I believe you need all the monitors set, if I recall it's something like 1999 or thereabouts where you were allowed one not set. It can be done, it's just real frustrating on them.

Check with the California Bureau of Automotive Repair (800) 952-5210 (BAR) with your issues. They may have a way to help you?

California smog inspections are an idiotic game. I know. I did them here for near 18 years! There's a potential they may send you to a "Referee" station to verify your issue, and "hopefully" give you a Cert. They 'should' know about the completion of the EGR self test issues - hopefully!

Also, go to the station that failed you, and ask them for the name of the Area BAR Rep and contact info (if they have it - and be sure to tell them it is "not" about a Station Complaint), and contact him/her too. He/She may also be able to help. The BAR will also be able to take your info to the Area Rep for a call back for you to explain your issues with him/her too.

For every stringent rule, there is an exception. Try and find one if you cannot get the EGR system to do a completed self test.
