II have 130,000 miles on the car but it runs perfectly. I've replaced the alternator and radiator in the past year as well. Now I went to get it inspected and it failed emissions due to the catalytic converter. Without taking my car to a shop that will charge me hundreds of dollarsjust to tell me whatwrong with the converter is there any other way I can?
If the test says it the issue.. you have no choice but to replace it.. (you could cut it apart and clean it out, then reweld it)..BUT if the inspectors see it,, you are IN BIG TROUBLE!!
SOURCE: Catalytic converter
As we can see in figure below it sit vertically up in the front of the car.
SOURCE: emmision test failed?
It is possible that the scan tool that the shops are using, is powered independently from the OBD11 connector, but the testing station relies on the connector for power and if the fuse for it is blown, they get no data and you fail.
I've attached a picture of the connector and where you should see 12 volts. Get a test light and check this pin, if you have no power between this pin and ground, you either have a blown fuse or a wiring problem

maybe i can help, the car has to be in a obd rhope this helpseadiness mode,thecar is probably not in this mode because it has not been driven enough or the(right way). you have do do a drive cycle to get the computer to go into obd readiness mode. also check pin #16 on obd connector tomake sure it has power. go to obd website for complete instructions on the DRIVE CYCLE it is rather long,
SOURCE: My car failed emissions with the following Codes
O2 Sensor in manifold has failed, replace it and have computer reset, hope this helps, let me know
SOURCE: TCS ABS lights on & alternator not fully charging
Alt shoud be putting out 14 to 15.2 volts.
