Service engine light on,needed 02sensor,replaced reset light off,drove 100 miles ,went for inspection says catalyst and evaporation sytem not reset

You may need to disconnect the battery for 60 seconds to get it to reset.

Generally speaking, the not ready issue means the truck has not been driven enough since the battery was disconnected or the codes were cleared to have a new history. The cycle drive needs to include about 50-100 miles of both city and highway driving with the engine at normal operating temp. The distance does not have to be done in one trip.

Maybe the light just needs to be reset "or" after changing some O2-sensor\'s you have to drive the car 50+ miles for the computer to reset and the light to go out. Go to you Mech or Advanced Auto and ask them to connect their meter and reset the check engine light, Advanced does it for free and they will tell you if something else is now wrong; maybe by changing both of those it tripped something else. did you put it on a meter after changing those? And, have you driven the car more than 50mi since changing them? I worked for a car dealer who changed a few O2 sensors in a minivan and I drove the sucker for over 100 miles before that light went out. That original 50+ miles is supposed to be non-stop driving too.

What does it say for that code? What sensor was replaced? Still showing what?

check for a bad connection like a bad ground at the battery, make sure both terminals are tight at the battery, the starter and the ground at the engine. the shop that installed the EGR should have erased the codes, after 50 to 100 miles you would be able to go through emissions.

Hello, have you tried to unhook the negative side of the battery for about 10 minutes and then go from there . It should reset the computer completely .

Hello
I would disconnect the battery for at least 20 seconds. Connect the battery drive the car for a least 5 miles at least 50 MPH that should reset it, if not you should have a scan tool connected to see what is going on, take care of the problem and clear the codes
Good luck

were this oem sensor (original) or after market? some times the after mark are not as good. the miles you did are this stop and go (city) or higwh ,there a certain procedure to reset this computers some cars take longer than othersget your mechanic to do it him self with the scanner or just keep driving it until it resets itself or gives a code.

they set the timing WRONG and that is an interference motor so the valves hit the pistons
