EGR error 1406
Got a service engine soon light about a 2months ago.. took off the egr
valve and found it to be really carboned up. Cleaned the ports and the manafold and put the old valve back on. It ran for about a month and the same problem again.. Replaced with a new valve and another cleaning.. after 30 days got the same error today. What can cause this?? It must be something that is causing the carbon build up?? gas?? plugs?? throttle body?? Air Filter?? The car runs good and get like 38MPG.. 96 saturn sc2 |

How much oil is the vehicle consuming? Is the PCV valve functioning
properly? I had cleaned out my son's EGR ('96 SL1) and it fixed the problem for about 15K miles. I then broke down and we replaced the EGR with a new one. We only have about 5-10K miles since then so I can't tell you if the problem will return. I am assuming you had the SEL code scanned and it indicted the EGR (code 32, IIRC) so you know this is the culprit?

yes I read the stuff on seafoam but don't think I'll do that.. Use to
do it many mnay years ago with a car and a carburetor using a product call mobile upperlube. Just manully held the throttle open and poured it down the barrel ever so slowly trying not to kill the engine.. All kinds of white smoke would come out the exhaust and you would keep this up until you had gone through the pint. Worked great but things are different now a days. |
