Question about 2008 Jeep Patriot
The first time I took it in to the shop, they scanned the code and said it had to do with the catalytic converter but they were unspecific about what could be wrong. Once they cleared the code and the 'check engine' light did not come back on, they did nothing further and told me to bring it back if the light came on again. Within a couple of days it came back on but it had gone out but the time I took it back in. They didn't charge me for scanning it again (code po420) but once the code was cleared they did not take any further action.
The po 420 is a sign of a bad cat , but how to make sure it to take the o2 sensor out that in just before the cat and see how it runs then will be loud and will not hurt anything just be carful and see if your car runs any differant sometimes just the 02 sensor goes bad , so if your car runs better with it out then your cat is going bad and you will not notice it at first , but as it clogs ,which the parts inside start to melt and break apart and starts to clog nothing to worry about it will just stop running but you will notice that way before it go bad ,
