New Member ! Questions about 1992 Honda Accord
So I am writing in the forum because I know absolutely nothing about cars and I do not want to take my car to a shop and be f***d over because of that . I have a 1992 Honda Accord Lx that will not pass smog because of my NO & CO emissions . At first all 3 emissions would not pass , but I had gotten a tune up and it fixed the HC .
The readings are : PCV : PASS Catalytic Converter : PASS Visual EGR : PASS Fuel Injection : PASS Vacuum Line Connections : PASS Fuel Cap Functional : PASS Fuel Evap Test : PASS Thermostatic Air Cleaner : N/A Air Injection System : N/a Ignition Spark Controls : PASS 02 sensors and connectors : PASS Functional EGR : N/A Fill Pipe Restrictor : N/A Fuel Evaporative Controls : PASS Fuel Tank Cap Visual : PASS Carburetor : N/A Wiring of Other Sensors or Switches : PASS Ignition Timing : PASS 15BTDC Liquid fuel Leaks : PASS HC at 15 mph at 25 mph MAX : 81 91 AVE: 27 21 MEAS : 56 53 CO at 15 mph at 25 mph MAX : 0.74 0.62 AVE : 0.16 0.11 MEAS : 1.50 1.48 NO at 15 mph at 25 mph MAX : 584 511 AVE : 270 207 MEAS : 621 835 If it is something easily fixable , please let me know ! |
Welcome to Honda Accord Forums. I moved your thread to get you more responses.
This link has some possible causes for high emission readings: Failed Smog: What causes high emissions, HC,CO,NO | Just Smogs |
The NO emissions problems can be caused by clogged EGR ports. It is a common problem on accords of your vintage. The common diy thread on top of the gen tech help forum has a link on how to clean the ports.
Your setup has the plugs that need to be removed by using a small slide hammer. |
