I had my catalytic converter replaced, because a year ago earlier replacement (OEM unit stolen) was discovered to be not the right converter (the garage installed the converter for a 2.7 liter motor). The truck passes the smog test (California), passes the visual test, but doesn't pass the functional test - obd2 port doesn't "see" the cat.
Immediately after installation of the new cat, check engine light came on.
Installer cleared code, didn't read it.
Have driven 200+ miles since, check engine light has not come on, but still fails because OBD2 port doesn't see the new converter. Emissions test is fine.
have the same problem?
