Question about Cars & Trucks
Had check engine light code P601 Bad PCM. Had PCM (or ECM as some call it) replaced. Was told to drive it for 3-4 days to let computer diagnose itself before getting emission test. Drove it 250 combined highway and city driving. Failed emmision test. Catalytic converter Notcompleted and Evap. System Notcompleted. Found out that the tank needs to be 15-85% full for Evap to test itself. Filled it for the emission test but had let it run low during the 250 miles. How much longer do I need to keep driving it to get those two systems to self test? No more codes have popped up. Mechanic says to just keep driving it. Have to get this done. Already two months overdue on tags and the tickets are stacking up.

Bank 1 is the converter on the side that engine cylinder one is on. Yes that is true about the converter, the computer is programmed for a certain value, an aftermarket cat will not meet that value and the check engine lite will be triggered.

P0420 is a cat code. Sometimes, you can replace the upstream & downstream air/fuel & O2 sensors, run some good fuel injection cleaner thru it, and that might fix the problem. If not, you may need to replace the cat. Note that the cat is covered under warranty for 8 yrs/80,000 miles. Toyota will replace it if it has gone bad, for free.

you're having the same problem i had with my 99 isuzu rodeo 2 wd 3.2 i paid a muffler guy over $600 to replace those catalytic converters, if you're good at welding you could do the welding yourself after buying the catalytics, basiclly i seen them just cut them off and welded them back on

HI, this guide will help you with this replacement.
Step1 Lift your jeep. Unfortunately, the catalytic converter sits about midway down the length of your jeep, so lifting one end or the other will not do. Ramps are your best bet to get you within reach of the parts when working from home. Luckily, this is usually the hardest part of this repair. Step2 Be patient with the bolts, as they are often hard to remove due to size and awkward placement. You may have to drill or saw bolts to remove them. With this in mind, you should pick up new bolts, nuts and seals for your replacement project. Step3 Buy a catalytic converter specific to your jeep to avoid extra work. A generic part must be welded into the jeep, while a vehicle-specific model comes pre-welded to the proper pipes for easy bolt-on installation. Step4 Remove the 02 sensor (with an O2 wrench) before unbolting the catalytic converter. Then, you should remove the pipe connecting the sensor to the converter. Depending on your exhaust system, you may have to remove more pipes before you unbolt the converter from the muffler. Step5 Replace the old catalytic converter with a new one. This should be the easy part, as you simply bolt the new part in place. Step6 Reattach the exhaust pipes and 02 sensor, and the basic job is done. Make sure you replace any cracked or rusty pipes while you have the exhaust system apart.
