A friend has codes 67 and 90 on his 98 Crv, what needs to be done to fix these

problems. I did a search and 67 says Catalyst low efficiency, and 90 says Evap

Emissions Control leak detected in fuel tank. I just need to know exactly what

needs to be replaced. Thanks in advance -Chad-

 

for the code 90 check the gas cap. Make sure it is tight, and clicks at least 3 times. Clear the code. If you it does not recode that is your problem. As for the code 67, I am not sure. I don't have a CR-V shop manual. Good Luck!

 

This question has already been answered, but thanks for the effort... -Chad-
