My check engine light just came on (p0420 OBDII code) on my 2001 tacoma. its a 3.4L v6. I've been smelling a burning smell as of the past week or so. It's a burning scent but can't tell where it's comming from. I don't see any oil leaks or any smoke.
As for the code it may be my Cat Converter or an 02 sensor?
From reading online I've also read that the reason the cat converter went out is because the motor is leaking oil internally and it's clogging the catalytic converter.
Does anyone have any experience with these types of issues?
I'm hoping I don't have to spend Thousands to fix this.
I know when the Cats go bad they smell like "rotten eggs" but the smell I'm getting is burning smell.
Also, I've read that going with an aftermarket catalytic converter is a waste although its much cheaper. I've read I should go with an OEM catalytic converter but its way more $. Let me know what you think.
