F355 inspection issue

That is very inconvenient. I hope someone responds with an answer for you. I will do some searches on the internet to see if I can find any information.

 

Are you sure your state requires all monitors to have recently run to completion?

I hope that is not the case because from what I have read that system takes many cycles, as much as 20 starting from a cold engine to a fully warm one.

I am sure you are aware of this but unless you hear the Air Pump's usual whistle when you start the car the system is not activated so that should give you an idea of how cold the engine needs to be. I don't think the car will get cold enough unless you leave it outside for several hours.

One thing I found in my search was that in CT someone posted that they passed emissions with one or two monitors not running. They claim the state limit there is not more then two monitors can be in-complete.

 

BRADAN,

what year is the 355 ? The emissions standards are less stingent on earlier monitors. The early obd2 cars here in PA were able to get by with all but one monitor being set. As CAN came around all momnitors needed to be set.

Attached is a link from the NYVIP discussing failures and rediness monitors. The last paragraph on the second page states that 1996-2001 can have no more than 3 incomplete and later cars can have only 2 not complete. So, if you are just missing 1, the Secondary Air system, you should be fine. I know here in PA when we test if we are not sure there is a station menu on the analizer to see if it is actually "ready for testing" ( will is pass screen !!). You may want to look into that further.

PS..The Secondary Air System is a 2 trip logic monitor.I have seen it take up to 250 miles and cold cycles to set.

Dont be diisappointed yet. Some cars are ready for scanning in 50 miles and others have to be driven 300 miles. My 97 355 had to put 278 miles on it to be ready and my friends BMW 540 went well over 300 mile mark. On the other hand, my 98 355 had less than 70 miles on it when I smogged it. I would recomment driving it a bit more before you take things apart.

Hope this helps

 

In Oregon they will let you have two cycles that are not set.

 

and also 2 in California.

 

Give me the car for a week, they'll be enough miles on her to run any test - I promise

Some monitors are specific to fuel level and will not run unless the fuel leve is inbetween 1/4 to 3/4 of a tank. later Chrysler and benz products are 1/2-3/4 of a tank for the monitors to run.

This is the basic monitor rest procedure we use :

Prerequisites:

-Erase DTC memory
-Coolant temperature must be between 80 deg C. and 110 deg. C.
-Intake air temperature must be between 10 deg. C. and 35 deg. C.
-Battery voltage must be a minimum of 12.5 V
-Fuel tank level 1/4 to 3/4 full.

Procedure

-Connect the scan tool
-switch the ignition on and start the vehicle
-Idle the vehicle for 2-3 minutes. This executes the O2S Heater, Misfire, Secondary AIR, Fuel Trim, and Purge system monitors
-Drive the vehicle at 45-55 mph for a continuous 7 minute period, avoid stopping. This executes the EVAP, O2S, Fuel Trim, and Misfire monitor.
-Accelerate the vehicle to an engine speed of 5000 RPM (with Automatic transmission use the tiptronic mode); lift off the throttle until the engine speed is around 1200 rpm. This executes the fuel cutoff
-Accelerate the vehicle smoothly to 60-65 mph, cruise constantly for 5 minutes, this executes the Catalust, O2S, Misfire, Fuel Trim, and Purge System monitors
-Decelerate and idle the vehicle again for 3 minutes. This executes the Misfire, Secondary AIR, Fuel Trim, and Purge System monitors
-Check the status of the readiness codes.
-If any engine monitor fails the drive cycle test, repeat the drive cycle test until all monitors have run through and passed.

When repeating the drive cycle operation for a failed EVAP monitor or thermostat-monitor, allow the engine to cool until the coolant temperature and the ambient air temperature are between 10 deg. C and 35 deg. C, with a difference between them no greater than 4 deg C is observed, and repeat the drive cycle operation.

Check. In California they got a fomula for failed drive cycles like 3/5 or 4/7 must work. Also top secret $6 aka mode6 is a diagnostic protocol in obd2 that works like a mil for subsystems. It is likely that you have a fault causing the failure not a drivecycle issue. But im not a pro so check-out what I post and let me know if I'm full of hot air.

Took me about 5 separate 20+ mile drives to store enough data to pass MA emissions.

 

Take it down the highway and some stop and go for 30 min, its about to kick in

Good luck
