Hi everyone,
I have a 2006 Acura TL that is up for inspection. The car had a dead battery. I have driven 1000 miles since then. The Catalyst mon and oxygen sen mon still showing inc. Anyone had the same problem or should I bring it to the dealer?
Thanks

Catalytic Converter Monitor and Readiness Code
NOTE:
- Do not turn the ignition switch off during the procedure.
- All readiness codes are cleared when the battery is disconnected, if the DTCs have been cleared, or if the ECM/PCM is reset with the HDS.
- Low ambient temperatures or excessive stop-and-go traffic may increase the drive time needed to switch the readiness code from incomplete to complete.
- The readiness code will not switch to complete until all the enable criteria are met.
- If a fault in the secondary HO2S system caused the MIL to come on, the readiness code cannot be set to complete until you correct the fault.
Enable Criteria
- ECT at 158 degrees F (70 degrees C) or higher.
- Intake air temperature (IAT) at 20 degrees F (-7 degree C) or higher.
- Vehicle speed sensor (VSS) reads more than 25 mph (40 km/h).
Procedure
1. Connect the HDS to the vehicle's data link connector (DLC), and bring up the READINESS CODES screen for Catalyst in the DTCs MENU.
2. Start the engine.
3. Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. After about 5 miles (8 km), the readiness code should switch to complete.
4. If the readiness code is still not set to complete, check for a Temporary DTC with the HDS. If there is no DTC, one or more of the enable criteria were probably not met; repeat the procedure.
Air Fuel Ratio (A/F) Sensor Monitor and Readiness Code
NOTE:
- Do not turn the ignition switch off during the procedure.
- All readiness codes are cleared when the battery is disconnected, if the DTCs have been cleared, or if the ECM/PCM is reset with the HDS.
Enable Criteria
ECT at 140 degrees F (60 degrees C) or higher.
Procedure
1. Start the engine.
2. Test-drive the vehicle unclear stop-and-go conditions with short periods of steady cruise. During the drive, decelerate (with the throttle fully closed) for 5 seconds. After about 3.5 miles (5.6 km), the readiness code should switch from incomplete to complete.
3. Check the readiness codes screen for the AIR FUEL RATIO (A/F) SENSOR in the DTCs MENU with the HDS.
- If the screen shows complete, readiness is complete.
- If the screen shows not complete, go to the next step.
4. Check for a Temporary DTC. If there is no DTC, the enable criteria was probably not met. Select the DATA LIST Menu. Check the ECT in the ALL DATA LIST with the HDS. If the ECT is lower than 140 degrees F (60 degrees C), run the engine until it is higher than 140 degrees F (60 degrees C), then repeat the procedure.
Air Fuel Ratio (A/F) Sensor Heater Monitor Readiness Code
NOTE: All readiness codes are cleared when the battery is disconnected, if the DTCs have been cleared, or if the ECM/PCM is reset with the HDS.
Procedure
1. Start the engine, and let it idle 1 minute. The readiness code should switch from incomplete to complete.
2. If the readiness code is still not set to complete, check for a Temporary DTC. If there is no DTC, repeat the procedure.
Fuel System Monitor and Readiness Code
- This readiness code is always set to available because the fuel system is continuously monitored during closed loop operation.
- Monitoring pauses when the catalytic converter, EVAP control system, and A/F sensor monitors are active.
- Monitoring also pauses when any related enable criteria are not being met. Monitoring resumes when the enable criteria is again being met.
