well i picked up a code scaner today

[ThatShoGuy]

well i pick up one of thos auto zone cheaper model code scaners ,now i can check them my self:woohoo:

this is the model if wondering..
http://actron.com/product_detail.php?pid=16350

well i have a question about one function it has?

has this (I/M Monitors) thing on it.

and in that it shows ready with a number (mine 7)

and INC. (incomplete) and a number (mine 2)

now these are what it monitors----------- --------------------------- these are what are ready on my car
misfire/misfire monitor-------------------------------------------------ready
fuel/fuel system monitor --------------------------------------------- ready
comp/comprehensive components monitor -----------------------------ready
catalyst/catalyst monitor---------------------------------------------- INC
htd cat/ heated catalyst monitor --------------------------------------ready
evap/evaporative system monitor -------------------------------------- INC
sec air/secondary air system monitor---------------------------------- ready
A/C /air conditioning refrigerant monitor--------------------------------- N/A
O2 snsr/oxygen sensor monitor-----------------------------------------ready
O2 htr/oxygen sensor heater monitor-----------------------------------ready
EGR/exhaust gas recirculation------------------------------------------ready

so what im tryin to figure out is how long does it take for the 2 INC marked ones to be ready???

i did have the code po455 but i had cleared it by still pulling the battery since this i put about 15miles no ses yet but i know its coming(keeps coming)

any input would be great
Thanks

However many drive cycles it takes to clear them. There is a description somewhere, maybe the PC/ED, that lists what conditions have to be met to clear the monitors. It's like "drive xx mph for x minutes, yy mph for y minutes, be at a specific temp range, operating conditions", etc. Just be patient and they'll clear or set a code.

Any time you clear the keep-alive memory, you're going to set P1000 (though the Actron scanners WON'T show that code) which will remain until all the monitors have passed. Usually 1-3 days of ordinary driving.

alright thanks
i was unsure how long it could take i know the evap is gonna set another code..

Evaporative Emission (EVAP) Running Loss System Monitor
The Evaporative Emission (EVAP) Running Loss System Monitor is an on-board strategy designed to detect a leak from a hole (opening) equal to or greater than 1.016 mm (0.040 inch) in the EVAP Running Loss system. The proper function of the individual components of the EVAP Running Loss system as well as its ability to flow fuel vapor to the engine is also examined. The EVAP Running Loss System Monitor relies on the individual components of the EVAP Running Loss system to apply vacuum to the fuel tank and then seal the entire EVAP Running Loss system from atmosphere. The fuel tank pressure is then monitored to determine the total vacuum lost (bleed-up) for a calibrated period of time. Inputs from the engine coolant temperature (ECT) sensor, intake air temperature (IAT) sensor, mass air flow (MAF) sensor, vehicle speed sensor (VSS), fuel level input (FLI) and fuel tank pressure (FTP) sensor are required to enable the EVAP Running Loss System Monitor.

Note: During the EVAP Running Loss System Monitor Repair Verification Drive Cycle a PCM reset with key on, engine off will bypass the minimum soak time required to complete the monitor. The EVAP Running Loss System Monitor will not run if the key is turned off after a PCM reset. The EVAP Running Loss System Monitor will not run if a MAF sensor failure is indicated. The EVAP Running Loss System Monitor will not initiate until the Heated Oxygen Sensor (HO2S) Monitor has completed.

The EVAP Running Loss System Monitor is executed by the individual components of the EVAP Running Loss system as follows:

The function of the EVAP canister purge valve is to create a vacuum on the fuel tank. A minimum duty cycle on the EVAP canister purge valve (75%) must be met before the EVAP Running Loss System Monitor can begin.
The canister vent (CV) solenoid will close (100% duty cycle) with the EVAP canister purge valve at its minimum duty cycle to seal the EVAP Running Loss system from atmosphere and obtain a target vacuum on the fuel tank.
The fuel tank pressure (FTP) sensor will be used by the EVAP Running Loss System Monitor to determine if the target vacuum on the fuel tank is being reached to perform the leak check. Once the target vacuum on the fuel tank is achieved, the change in fuel tank vacuum for a calibrated period of time will determine if a leak exists.

If the initial target vacuum cannot be reached, DTC P0455 (large leak or no purge detected) will be set. The EVAP Running Loss System Monitor will abort and not continue with the leak check portion of the test.

If the initial target vacuum is exceeded, a system flow fault exists and DTC P1450 (unable to bleed-up fuel tank vacuum) is set. The EVAP Running Loss System Monitor will abort and not continue with the leak check portion of the test.

If the target vacuum is obtained on the fuel tank, the change in the fuel tank vacuum (bleed-up) will be calculated for a calibrated period of time. The calculated change in fuel tank vacuum will be compared to a calibrated threshold for a leak from a hole (opening) of 1.016 mm (0.040 inch) in the EVAP Running Loss system. If the calculated bleed-up is less than the calibrated threshold, the EVAP Running Loss system passes. If the calculated bleed-up exceeds the calibrated threshold, the test will abort and rerun the test up to three times.

If the bleed-up threshold is still being exceeded after three tests, a vapor generation check must be performed before DTC P0442 (small leak detected) will be set. This is accomplished by returning the EVAP Running Loss system to atmospheric pressure by closing the EVAP canister purge valve and opening the CV solenoid. Once the FTP sensor observes the fuel tank is at atmospheric pressure, the CV solenoid closes and seals the EVAP Running Loss system.

The fuel tank pressure build-up for a calibrated period of time will be compared to a calibrated threshold for pressure build-up due to vapor generation.

If the fuel tank pressure build-up exceeds the threshold, the leak test results are invalid due to vapor generation. The EVAP Running Loss System Monitor will pass and complete.

If the fuel tank pressure build-up does not exceed the threshold, the leak test results are valid and DTC P0442 will be set.
The malfunction indicator lamp (MIL) is activated for DTCs P0442, P0455 and P1450 (or P446) after two occurrences of the same fault. The MIL can also be activated for any EVAP Running Loss system component DTCs in the same manner. The EVAP Running Loss system component DTCs P0443, P0452, P0453 and P1451 are tested as part of the Comprehensive Component Monitor (CCM).
