i have a 98 civic ex, that wont pass smog due to 3 monitors not running... its the oxygen sensor, catalyst, and evap sys i believe... there is no check engine light or codes being thrown, it just says those monitors are incomplete. everything seems to be fine, but they wont run. i hadn't disconnected my battery in like 2 years prior to that and put like 20,000 miles on it so they should have run or something should have happened. i just recently reset my ecu to see if the monitors would run but so far they have not, and i have put like 100 or so miles on the car since the reset. Anyone have any ideas? honda will look at it for a starting fee of $170, and since im broke right now im just trying to find some solution on my own.... for it to pass smog i just need to get one more monitor to run.

Thanks for your help!

The vehicle should be driven approximately 7.5 miles within a period of approx. 23 minutes (1372 seconds) from a cold start. However, due to manufacture variations, it is necessary to perform only as much of the Drive Cycle as is necessary to reset the required monitors to a "Ready" status. Operate the throttle smoothly to obtain best results. Do not shut the engine off during the drive cycle.
Step 1 (Engine Cold) Start engine, idle 20 seconds. Accelerate gradually and drive at 20-25 mph for 1 minute, varying speed.
Step 2 Accelerate gradually to 32 mph within 35 seconds. Decelerate to 0 mph in 10 seconds. Idle for 40 seconds.
Step 3 Accelerate at part throttle to 25 mph in 10 seconds. Cruise at 17-25 mph for 15 seconds. Accelerate gradually to 57 mph in 45 seconds. Cruise at 50-56 mph for 1 minute. Decelerate gradually to 0 mph in 40 seconds. Idle for 15 seconds.
Step 4 Accelerate at part throttle to 36 mph and maintain for 10 seconds. Decelerate to 0 mph in 15 seconds. Idle for 5 seconds.
Step 5 Accelerate to 30 mph and back to 0 mph within 30 seconds. Idle for 20 seconds.
Step 6 Accelerate to 36 mph in 20 seconds. Drive at 35 mph for 20 seconds. Decelerate to 0 mph in 15 seconds. Idle 5 seconds.
Step 7 Accelerate gradually to 26 mph and decelerate to 0 within 40 seconds. Idle 15 seconds.
Step 8 Accelerate to 27 mph in 40 seconds. Decelerate to 0 mph in 10 seconds. Idle 25 seconds.
Step 9 Accelerate to 26 mph in 15 seconds, maintain speed for 10 seconds, decelerate to 0 mph in 10 seconds. Idle 15 seconds.
Step 10 Accelerate to 23 mph in 20 seconds, decelerate to 0.5 mph in 10 seconds (no complete stop). Accelerate to 28 mph and back to 0 mph (momentary stop 1 second) within 35 seconds.
Step 11 Accelerate gradually to 34 mph in 45 seconds. Vary speed between 34 and 19 mph for 2 minutes. Decelerate from 25 to 0 mph in 25 seconds. Idle for 5 seconds.
Step 12 Accelerate to 29 mph in 15 seconds, decelerate gradually to 0 mph in 45 seconds. Idle for 30 seconds.
Step 13 Accelerate gradually to 28 mph and back to 0 mph (momentary stop 1 second) within 50 seconds. Accelerate gradually to 27 mph and back to 0 mph within 55 seconds. Idle for 15 seconds.
Step 14 Accelerate to 24 mph and back to 0 mph within 18 seconds. Idle for 10 seconds. Accelerate gradually to 22 mph and back to 0 mph within 50 seconds. Idle for 8 seconds.
Step 15 Accelerate gradually to 30 mph within 50 seconds. Decelerate to 0 mph in 10 seconds. Idle for 25 seconds.
Step 16 Accelerate to 23 mph and back to 0 mph within 30 seconds. Idle for 10 seconds.
Step 17 Repeat steps 1 - 16 once again. Recheck the status of the "Readiness Monitors".

NOTE: Remember, clearing DTC's or interrupting power to the ECM after the readiness monitors have been reset to "Ready" will require that the Drive Cycle be repeated.

Completing the Drive Cycle successfully one (1) time should reset most drive cycle monitors to a "Ready" status. However, there are "two trip" monitors, which require that the drive cycle be successfully completed two (2) times, to achieve a "Ready" status. Furthermore, systems which use averaging, may require the drive cycle to be completed more than 2 times. It is necessary to perform only as much of the Drive Cycle as is necessary to reset the required monitors to a "Ready" status

"this is taken directly from alldata" i always do this and have never had any issues. if this doesnt work then you might have some problem with the computer losing power after you shut the vehicle off. i have never been unable to get the monitors set within 25 mins or so of driving unless its a dodge van or truck which some of them take like 60 warm up cycles to complete. hope this helps

thats also pretty lame that they charge 170$ for 20 mins of work. i only charge people like 40 bucks. there is also a special little tool you can buy i think made by osp or something. but you just plug it into the DLC and when it turns green and beeps the monitors are set.

unless you have a scan tool where you can check it.

just got a recall for the emission system in the mail for my 97 ex 4 door, 98 ex coupe, and my 97 ex crv. yup all 3. you should of got one. one statement says IF YOUR VEHICHLE FAILS A STATE SMOG CHECK, OR THE MALFUNCTION INDICATOR LAMP COMES ON, take your car to a honda dealer.Under the terms of the warranty extension, the dealer will repair any emissions-related problem free of charge(including diagnosis,parts, and labor) In 1998 honda entered into an agreement with U.S EPA and CARB. the reason for this agreement was a assertion by epa and carb that there is a technical problem with hondas on board diagnostic system that causes it not to comply with the federal clean air act and california regulations. the extension was for 14 years the cars was first sold, or 150k miles. Hope this some help.

well thanks for the tips, i think ill start with trying to idle the car for 20 min or so, the driving test seems impossible to complete on a regular street, but i dont know if nothing else works im willing to try it. After i reset my monitors they all completed except for those three i said earlier, once i started my car back up... oh yea and as for the dealership doing some work, i called another honda in my hometown and the guy i talked to cut me off and said they dont do smog work or repairs, and after i was trying to explain i just need to find out why my monitors arent running he told me to call back on monday and talk to someone else!! oh well... Thanks again anyone else have anything? ill keep you guys updated!

well.... since i reset my ecu, i put about 200 miles on it, pulled it into the smog shop and my monitors had run!!! so i passed smog. maybe it was just some freak thing where my ecu was stuck.... i dont know, but thanks for the help!

word.. congrats on not paying honda 170 bucks to do that simple ****.
