I found my groundstrap hanging off of the second catalytic converter along the exhaust system. Isn't the cat converter grounded by different means?

Would this cause a 420 error? My check engine light comes on intermittently and whenever I take it to autozone to get it checked out - it's the 420 code (i think that's the 02 sensor defunct code??)

Any suggestions?

Also iRotors.com product rocks.

 

that strap hanging isnt causing any problems. mine hung off the whole time i owned it and some people on here have removed it all together

 

do you know what the strap was for initially.

 

anybody know what the function of the groundstrap is for the 2nd cat converter? if it's hanging off - what is the use???

 

the function is to ground

but like i said, it doesnt cause i problem if its hanging

 

Since you have a potential of creating a static charge (in the same manner as a Van De Graaff generator generates one) the strap may be there to eliminate any potential build-up. But that's just an uneducated guess...
