xrap Posted September 10, 2007 Report Share Posted September 10, 2007 Our Honda civics jsut went for a emission test and it had one thing failed. It says no ppm and I went to the driveclean.com website and searched ppm but I don't really understand what it means. Can anyone explain it to me a little better?

ccmtcanada Posted September 10, 2007 Report Share Posted September 10, 2007 I thought ppm stood for "parts per million". Each emission (eg Hydrocarbon, Nitric Oxide), has a threshold of how many ppm is acceptable. If it's over that amount, that part of the test fails.

Hooked Posted September 10, 2007 Report Share Posted September 10, 2007 Remember, its important to drive your car for a good 20 minutes, preferably some type of hiway driving, before taking it to get tested. Better chance of it passing then. Link to comment Share on other sites More sharing options...
xrap Posted September 10, 2007 Author Report Share Posted September 10, 2007 Yep, your right hooked. I told my brother in law to do that but he didn't and jsut yesterday he poured a bottle of engine injector to clean it out a bit and the smoke from the exhaust was coming out white. Bad idea, and now he''ll be paying for it again. Link to comment Share on other sites More sharing options...
