Exactly right!Did you clear the codes before you tried the driving in third trick? Have to do that so there are no codes stored in the computer.
I fully agree, it's the most-used diagnostic tool I have.I would invest in a scan tool that can read emmissions readiness monitors and the tcm. I don't think you would ever regret it, can use on tons of cars and really makes diagnosing problems easier.
Once you learn how the tests work it is pretty simple to get all of them to pass in a short drive.The monitors take longer to set then I expected but I think you should have been in the clear.
1:22pm 133508 ignition on, engine off (and cold!) -- reset the scan codes
1:23pm 133508 Started engine and checked monitors. The following monitors
had already completed their tests:
Misfire
Fuel System
Component
1:24pm 133508 Left Jeep idling while I opened the gate, then drove the Jeep out
to the driveway where I left it idling, closed the gate, locked up the
house, and drove to the freeway.
1:39pm 133511 On the freeway going 64mph -- man, the traffic and signals getting
to the freeway were slow!
1:44pm 133515 At the undercrossing to turn around and go back.
1:44pm 133515 Turn off engine for 9 minutes and unplug scan tool -- doing some
errands
1:53pm 133515 Start engine again, plug in scan tool and the following monitors
have completed their tests:
Misfire
Fuel System
Component
Catalyst
O2 Sensor
14:03 133521 Turn off engine -- more errands
14:07 133521 Start engine, plug in scanner, and all monitors have completed their
tests.
Total elapsed time: 43 minutes
Total distance: 13 miles
Probably should have mentioned mine is a 2001 RWD. And when hot, it sometims slips in reverse. I found a connector disconnected in the back of the transmission that I can't figure out where it goesHello I am having the same problem. The noise is pretty noticeable even in park. I just cleared the code and will drive it to get it ready for emissions. I do have a question. I was going to replace the torque converter like it was suggested here, but is that safe to do without a transmission rebuild? Is it safe to replace the converter by itself. I've been working on cars for a few years, but honestly the extent of my transmission knowledge is limited to R&R. Just want to make sure I'm not wasting time and money, or ruin a new converter by replacing just the converter.
BTW.... thank you all for all the information posted here.
