Catalyst Efficiency Monitor
The Catalyst Efficiency Monitor uses an oxygen sensor before and after the catalyst to infer Hydrocarbon
conversion efficiency, based on oxygen storage capac ity. Under normal closed-loop fuel conditions, high
efficiency catalysts have significant oxygen storage, which makes the switching frequency of the rear
HO2S quite slow compared with the switching freque ncy of the front HO2S. As catalyst efficiency
deteriorates, its ability to store oxygen declines and the post-catalyst HO2S signal begins to switch more
rapidly, approaching the switching frequency of the pre-catalyst HO2S.
In order to assess catalyst oxygen storage, the monitor compares front and rear HO2S signals during
closed-loop fuel conditions after the engine is warm ed-up and inferred catalyst temperature is within
limits. Front H02S signals are accumulated in up to ni ne different air mass regions or cells although 3 air
mass regions is typical. Rear H02S signals are counted in a single cell for all air mass regions. Currently
there are two algorithms that can be used to compare the front and rear HO2S signals:
1. Switch Ratio method;
The Switch Ratio method compares the 'switch frequencies' of the front and rear HO2S sensors. A
'switch' is counted every time the HO2S voltage output passes through a defined threshold (0.45 V).
The catalyst condition is diagnosed by dividing the number of rear H02S switches by the number of
front HO2S switches.
2. Index Ratio method.
The Index Ratio method calculates and compares the length of the front and rear HO2S signals. The
catalyst condition is diagnosed by dividing the length of the rear HO2S signal by the length of the front
HO2S signal.
A Switch / Index Ratio near 0.0 indicates high oxygen storage capacity, hence high HC efficiency. A
Switch / Index Ratio near 1.0 indicates low oxygen storage capacity, hence low efficiency. To improve the
robustness of the monitor, the Switch / Index Ratio is calculated using an Exponentially Weighted Moving
Average (EWMA) algorithm. If the Switch / Index Ratio exceeds the threshold, the catalyst is considered
failed.

SAIR System Monitor – Flow Check
When the air pump is energized, the MAF sensor will show a corresponding increase in airflow. The
SAIR pump flow check monitors the MAF sensor signal and two air flow models during normal
secondary air system operation to determine if secondary air is being delivered into the exhaust system.
The SAIR pump flow test compares the actual change in MAF during the pump on and off transitions to
the expected change in airflow from the secondary air fl ow model. (A throttle body flow model is used to
"zero out" errors in the air meter and to compensate fo r transient driving conditions.) The actual airflow is
divided by the expected airflow to calculate an "On flow ratio" and an "Off flow ratio".
A flow ratio that is much less than 1.0 means that the air pump has no/low flow, or the inlet hose to the
pump is disconnected. If secondary air system operation ex tends into closed loop fuel, fuel trim feedback
is used to discriminate between low pump flow and in let hose disconnection. A low flow ratio with a lean
fuel system indicates a disconnected inlet hose. A flow ratio significantly higher than 1.0 (and/or a rich
fuel system indication) indicates that th e outlet hose from the pump is disconnected.
SAIR Diagnostic
The V8 uses the standard FORD non-intrusive monitor that has been adapted for use on a V-engine. The
detection capability is detailed below with the V8 specific modifications highlighted
P0410 - Pump inlet hose disconnection.
P0491 - Low airflow into the exhaust on Bank1. Blocked hose OR failed to open vacuum valve.
P0492 - Low airflow into the exhaust on Bank 2. Blocked hose OR failed to open vacuum
valve.
P2448 - Low airflow into the exhaust on Bank1. Disconnected outlet hose.
P2449 - Low airflow into the exhaust on Bank 2. Disconnected outlet hose.
P0412 - SAIR electrical circuit fault high/low on ecu control pin.
P2257 - SAIR electrical circuit fault high on monitor pin.
P2258 - SAIR electrical circuit fault low on monitor pin.
The determination of which bank is receiving low ai rflow is performed by monitoring the closed loop
fuelling correction supplied from the oxygen sensors. The bank that has the highest enleaning correction is
the bank that has the lowest SAIR flow. If closed loop fuelling is not active when the SAIR pump is
disabled the diagnostic cannot determ ine which bank is receiving low flow and so a fault on both banks is
raised.
The relative difference between the commanded lambda values for each bank is used to determine a
restricted flow to either bank1 or 2 due to a restricted outlet. This enables P0491, P0492 to be raised if the
flow ratio is calculated as in range.
The SAIR functional tests run when SAIR is active and the results are stored until the HEGO monitor has
completed (150-200 seconds after SAIR is off on a typical FTP74). It is only when the HEGO monitor has
completed successfully that any functional SAIR fa ults and SAIR monitor complete is reported.

For barometric pressures below 22.5"Hg, the MIL will not illuminate for the indicated EGR DTCs.
For intake air temperatures below 20 deg F, the MIL will not illuminate for the indicated AIR DTCs.
