* The engine is in Closed Loop status.
* The engine coolant temperature (ECT) is between -40 and +150掳C (-40 and +302掳F).
* The intake air temperature (IAT) is between -20 and +150掳C (-4 and +302掳F).
* The manifold absolute pressure (MAP) is between 10-255 kPa (1.45-37 psi).
* The vehicle speed is less than 134 km/h (83 mph).
* The engine speed is between 375-7,000 RPM.
* The mass air flow (MAF) is between 1-510 g/s.
* The barometric pressure (BARO) is more than 70 kPa (10.2 psi).
* The fuel level is more than 10 %.
* This diagnostic runs continuously when the above conditions have been met.
Conditions for Setting the DTC
* The average long term FT weighted average value is more or less than a calibrated value.
* The above condition is present for approximately 3 min after the Conditions for Running the DTC have been met.
Action Taken When the DTC Sets
The ECM records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the ECM stores this information in the
Failure Records. If the diagnostic reports a failure on the second ignition cycle the ECM records the operating conditions at the time of the failure.
The ECM writes the operating conditions to the Freeze Frame and updates the Failure Records. The ECM illuminates the malfunction indicator
lamp (MIL) when one of the following occur:
* The ECM detects the same fuel trim failure during 2 consecutive trips.
* The ECM detects any fuel trim failure during any subsequent trip if the conditions at the time of failure meet the following criteria:
- The engine load is within 20 % of the previous test that failed.
- The engine speed is within 375 RPM of the previous test that failed.
- The engine coolant temperature is in the same range of the previous test that failed.
Conditions for Clearing the MIL/DTC
* The ECM turns OFF the malfunction indicator lamp (MIL) at the beginning of the fourth ignition cycle, after 3 ignition cycles that the
diagnostic runs and does not fail.
* A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
* A history DTC and related Freeze Frame data clears after 40 warm-up cycles, if no failures are reported by this or any other emission related
diagnostic.
* Clear the MIL and the DTC with a scan tool.

Circuit/System Verification
* Disregard any transmission symptoms, antilock brake system (ABS) indicators, and traction control system (TCS) indicators until any fuel
trim faults are repaired. A fuel trim fault may cause default actions such as harsh shifts and illumination of the ABS/TCS indicators.
* E85 compatible engine only-Over estimation of the ethanol content will result in a rich shift of fuel trim values, and under-estimation will
result in a lean shift of fuel trim values. A fuel trim DTC may set if the learned alcohol content, Fuel Alcohol Content parameter on the scan
tool, is different than the measured alcohol content in the vehicle such that fuel trim values exceed failure threshold values. Refer to Fuel
Composition Diagnosis (See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Component Tests and
General Diagnostics).
* Verify that other DTCs are not set.

Note: Do not run secondary air injection pump for more than 1-2 minutes at a time. Running for an extended period of time without allowing
pump to cool may cause damage to the pump.
1. Ignition ON, observe the DTC information with a scan tool. Verify that DTC P2431, P2432, or P2433 is not set.
瀚慖f a DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble
Code (DTC) List - Vehicle) for further diagnosis.
2. Observe the scan tool Secondary Air Injection Pressure Sensor voltage parameter. The reading should be between 1.0-4.0 V.
3. Compare the scan tool BARO pressure parameter to the Altitude Versus Barometric Pressure (See: Powertrain Management/Computers and
