Failure of EGR Valve or EVAP Solenoid on Acura MDX
Viewing 1 - 4 of 4 comments
My check emissions light would sporadically flash on and off for a few weeks. The dealer said it could be the gas cap. After it started to stay on, I took it in and found that it was a failed valve EGR Valve. Had it replaced and it solved the issue.
EGR valve failed or so it appreared and check engine light came on. Removing the valve and giving it a good bath in Sea Form resolved the problem and it is still going strong after 10K miles of use. Better still, just replace with a new genuine value from Acura. Very easy to do..
Replace evap. vent valve and evap. cannister.
EGR light came on at 104500. Had to have the valve replaced. Cost $350
