I have actually 2002 Sienna XLE van. I acquired engine check code P0420 which says "Catalyst system Efficiency listed below threshold (Bank 1)." So, ns bought CATACLEAN from Amazon. Ns have currently mixed this cleaner liquid as soon as gas tank is about 1/4th full and poured 12 oz. That liquid. Drive the van for 15 minutes before I filled increase gas tank. I have repeated this for 2 times and third time is walk on. However I don"t see engine check light walking off and it is quiet on. What should I do? please advise. Thanks.

You either require O2 sensors, A/F sensors (assuming the "02 supplies A/F sensors the method my "06 does) or a new cat (really, the whole exhaust manifold and also cat, since they"re all one-piece. If you take it somewhere, they will tell you the you require a new cat. New cat frequently will set you ago at the very least $1k. All 4 Denso sensors will set you back about $650. The sensors can fix the problem but, if you have to replace the cat, i would replace the sensors at the exact same time to save on future labor.

Could be as an easy as a clogged wait filter. Several on another thread suggested that, so ns tried it. Popped in a new filter and the password went away and also has no come back.A brand-new PCV valve has taken treatment of it for others.

That"s definitely the cheapest, easiest fix! Actually, the should most likely be action two for all automobile problems... Action one, execute you have gas? action two, have actually you adjusted the air filter in the last 9 months?

Same! i picked up a "63 Rambler one time and took it because that a check drive under the low-slope downhill street. At the bottom that the street, the car died. Unsure of the issue, I thrust the car fifty percent the way back increase the street to the driveway. Mine The dad of my then girlfriend/now wife come home and also asks, "Did you check if it had gas?" Gauge check out 1/2 tank. He added a gallon and it started ideal up.
