I've searched the boards for hours looking through information about this particular code. Alas, I couldn't decide what to do first and how to do it.
Code: p0403
2001 Mitsubishi Eclipse Spyder GT, manual transmission
Problem: Service Engine Light came on. Car seems to run normal. Doesn't die, idles normally, with the exception that it gets a little hotter than normal. The temperature goes back to normal while driving though.
I read that there are basically three things I can do to solve this problem.
A. Replace the EGR
B. Replace the EGR Solenoid
C. Check the Vac hoses for leaks
Okay, my issue. I do not know where the EGR valve is. I've searched and thought it was on the drivers side, almost in the middle, above the intake manifold and next to the intake, has like a goldish colored top. I'm not sure if that was it or not. I also googled to try to find images of the EGR valve, with no results. Knowing where the EGR valve actually is would be really great. Pictures would be even better. The reason I'm hesitant that this is the valve is because a friend told me that the EGR valve is on the passenger side on the side of the manifold. What holds this on, just 2 12mm bolts?
Okay. I've read that you can check the hoses by just spraying carb cleaner on them and seeing if they are leaking, true?
Lastly, is there a way I can see if the Solenoid is actually good or bad. I'd really hate to buy one of those and then it not be the problem. Also, where is this. From what I've read this is just a brown plugin, correct? If you have any extra pictures of the solenoid this would also be helpful.
Whats the first thing you'd do if this code came up for you?
Any pictures or detailed explanations would be amazingly helpful and I'd appreciate it. I'm a young college student and money is scarce right now. Please do not flame me, telling me to search because I have for hours.
Thank you for taking the time to read and reply to this post.
) Vac leaks are easy to find by spraying carb cleaner around areas that could be leaking (vac lines, nipples, solenoids, canisters, gaskets, etc) while the engine runs. If the idle speed changes while spraying then you found a leak.
