Can not start smog check.
Smog check mec showed my computer and Evaporative system and secondary air system not complete on screen.He said car computer not reading or getting a code.
2004 model with 86000 miles,no mods with regular maintenance.Couple of days ago had check engine light come on with code for the MAF/IAT intake.
Cleaned the censor and reset the check engine light and has driven about 150 miles with no check engine light.
Anyway I can get the computer to read these two systems?
Had this car for 4 years with no problems.

Typically the ODB2 will report "not complete" for all systems after a battery disconnect or ECU reset. Each system requires a set of conditions for the ECU to determine that it's functioning properly, and some of them take multiple drive cycles, the evap and air pump are two which take a few drive cycles.
Resetting the ECU to clear the MAF/IAT intake also put these two systems into incomplete, and the ECU is waiting for the all clear. How many times have to driven more than ~10 miles since the reset? Full warm up while driving, full cool down while off.

There is a specific "drive cycle" to reset the monitors...it works well most of the time. It can take a few weeks of day to day driving to set them otherwise. The procedure is in the service manual...If you don't have one I could do quick writeup when I get home from work

From the OEM documentation:
2005 - RX8 - Workshop Manual - Engine
OBD‐II ON‐BOARD SYSTEM READINESS TEST
This shows the OBD-II systems operating status. If any monitor function is incomplete, WDS or equivalent will identify which monitor function has not been completed. The Fuel system, Misfire and CCM are continuous monitoring-type functions. The HO2S, Thermostat, AIR system, Catalyst and EVAP system will be monitored under drive cycles. The OBD-II diagnostic system is initialized by performing the DTC cancellation procedure or disconnecting the negative battery cable.

2005 - RX8 - Workshop Manual - Engine
OBD‐II DRIVE MODE
Using the OBD-II drive mode, the monitoring item requested by OBD-II regulations can be easily diagnosed.
Performing the Drive Mode inspects the OBD-II system for proper operation and must be performed to ensure that no additional DTCs are present.
The OBD-II drive mode is divided into the specific drive mode and single drive mode.
For the specific drive mode, specified drive modes have been set for each individual monitoring item requested by OBD-II regulations, and they can be diagnosed individually. For the single drive mode, the entire monitoring item requested by OBD-II regulations can be diagnosed.
The following modes are in the specific drive mode. The applicable system is diagnosed by driving in the following drive modes.
Mode 3 (HO2S heater, HO2S, and TWC Repair Verification Drive Mode)
Mode 5 (AIR System Repair Verification Drive Mode)
Mode 6 (EVAP System Repair Verification Drive Mode)
The following systems are diagnosed with the single drive mode.
HO2S heater
HO2S
TWC
AIR System
EVAP System
CAUTION:
While performing the Drive Mode, always operate the vehicle in a safe and lawful manner.
When the WDS or equivalent is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the WDS or equivalent using the PID/DATA MONITOR AND RECORD function and inspect later.
NOTE:
Vehicle speed and engine speed detected by the PCM may differ from that indicated by the speedometer and tachometer. Use the WDS or equivalent to monitor vehicle speed and engine speed.
If the OBD-II system inspection is not completed during the Drive Mode, the following causes are considered:
The OBD-II system detected a malfunction.
The Drive Mode procedure was not completed correctly.
Disconnecting the battery will reset the memory. Do not disconnect the battery during and after the Drive Mode.
The WDS or equivalent can be used at anytime through the course of the Drive Mode to monitor the completion status. Monitoring can be done by viewing the ON BOARD SYSTEM READINESS menu.
The RFC diagnostic status can be confirmed with the ignition switch operation. During KOEO, the MIL illuminates for a fail-light inspection for approx. 17 s. The RFC diagnostic status is confirmed after the fail-light inspection.
If all of the RFC diagnostic is completed even one time, the MIL will continue to illuminate.
If all of the RFC diagnostic is not completed, the MIL flashes for approx. 7 s, and then it illuminates until the engine is started.
Mode 3 (HO2S heater, HO2S, and TWC Repair Verification Drive Mode)
1. Verify that all accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
2. Drive the vehicle as shown in the graph. The driving condition before driving at constant speed is not specified.
3. Stop the vehicle and access the ON BOARD SYSTEM READINESS to inspect the Drive Mode completion status.
If completed, RFC changes from No to Yes.
If not completed, turn the ignition switch off, then go back to Step 2.
4. Access the DIAGNOSTIC MONITORING TEST RESULTS to inspect the monitor results.
If detect values are not within specification, repair has not been completed.
5. Verify that no DTCs are available.
Mode 5 (AIR System Repair Verification Drive Mode)
1. Verify that all accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
2. Drive the vehicle as shown in the graph. The driving condition before driving at constant speed is not specified.
3. Stop the vehicle and access the ON BOARD SYSTEM READINESS to inspect the Drive Mode completion status.
If completed, RFC changes from No to Yes.
If not completed, turn the ignition switch off, then go back to Step 2.
4. Access the DIAGNOSTIC MONITORING TEST RESULTS to inspect the monitor results.
If detect values are not within specification, repair has not been completed.
5. Verify that no DTCs are available.
Mode 6 (EVAP System Repair Verification Drive Mode)
NOTE:
If the Mode 6 cannot be performed (you cannot drive the vehicle under the Mode 6 condition), perform the “Evaporative System Test” as an alternative. (See Evaporative Emission (EVAP) System Leak Inspection.)
NOTE:
If the Mode 6 cannot be performed (you cannot drive the vehicle under the Mode 6 condition), perform the “Evaporative System Test” as an alternative. (See Evaporative Emission (EVAP) System Leak Inspection.)
1. Drive the vehicle as shown in the graph. The driving condition before driving at constant speed is not specified.
2. Stop the vehicle and access the ON BOARD SYSTEM READINESS to inspect the Drive Mode completion status.
If completed, RFC changes from No to Yes.
If not completed, turn the ignition switch off, then go back to Step 1.
3. Access the DIAGNOSTIC MONITORING TEST RESULTS to inspect the monitor results.
If detect values are not within specification, repair has not been completed.
4. Verify that no DTCs are available.
Single Drive Mode (HO2S heater, HO2S, TWC, AIR System and EVAP System Verification Drive Mode)
1. Verify that all accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
2. Clear the DTC and from the PCM memory using the WDS or equivalent.
3. Drive the vehicle as shown in the graph. The driving condition before driving at constant speed is not specified.
4. Stop the vehicle and access the ON BOARD SYSTEM READINESS to inspect the Drive Mode completion status.
If completed, all of RFC changes from No to Yes.
If not completed, turn the ignition switch off, then for the monitoring item that was not in the detection condition, perform the applicable specific drive mode.
5. Access the DIAGNOSTIC MONITORING TEST RESULTS to inspect the monitor results.
If detect values are not within specification, repair has not been completed.

Note, the single drive mode to address all of them is:
idle more than 10 minutes
key off more more than 6 hours
idle more than 9 minutes
more than 55mph for 1 minute in highest gear
45-55 for 5 minutes in highest gear
5 seconds of deceleration in MT 4th or AT 3rd from more than 55mph to less than 45mph, repeated 10 times
ignition key off more than 10 minutes.
I believe these are cumulative for each, it will wait at the current step until you have accumulated the idle time, driving speed and time, decelerations, etc...
If you had 2 cycles over 150 miles, I'd bet that your next time out will either finish the process or show the light cleared.

Update.Did the drive cycle and passed smog with flying clolors.Teq said very clean test and no problems.I also found out that my Actron engine code reader can check my smog system,which I did before going to the test center.
