DTC P2096 Post Catalyst Fuel Trim System Low Limit

Fuel trim bias is used to keep the post catalyst air/fuel ratio within a predetermined range. This allows optimal
catalyst efficiency under various operating conditions. The engine control module (ECM) constantly monitors
how lean or rich the fuel trim bias is commanded, to determine if the fuel trim bias is greater than a calibrated
amount.
Conditions for Running the DTC
P0016, P0017, P0030, P0036, P0053, P0054, P0101, P0102, P0103, P0106, P0107, P0108, P0111,

P0138, P013A, P013B, P013E, P013F, P0140, P0141, P015A, P015B, P0201, P0202, P0203, P0204,
P0261, P0262, P0264, P0265, P0267, P0268, P0270, P0271, P0300, P0301, P0302, P0303, P0304,
P0340, P0341, P0365, P0366, P0411, P0442, P0443, P0446, P0449, P0452, P0453, P0455, P0496,
P1248, P1249, P124A, P124B, P2147, P2148, P2150, P2151, P2153, P2154, P2156, P2157, P219A,
P2227, P2228, P2229, P2230, P2270, P2271, P2440, or P2444 is not set.
The barometric pressure (BARO) is greater than 70 kPa (10.2 PSI).
The manifold absolute pressure (MAP) is between 0-200 kPa (0-29 PSI).
The intake air temperature (IAT) is between -20°C and +50°C (-4 and +122°F).
The start up engine coolant temperature is warmer than -20°C (-4°F).
The fuel control intrusive diagnostics are not active.
The engine is operating under cruise, light acceleration, or heavy acceleration.
DTCs P2096 and P2097 run continuously when the conditions above have been met.
Conditions for Setting the DTC
The correction limit for a condition causing a lean or rich air/fuel ratio has been exceeded.
Action Taken when the DTC Sets
DTCs P2096 and P2097 are Type B DTCs.
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 occurs:
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 percent 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
DTCs P2096 and P2097 are Type B DTCs.
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.
Diagnostic Aids
The post catalyst fuel trim diagnostic is very sensitive to heated oxygen sensor (HO2S) design. A non-OE sensor or an incorrect part number may cause a DTC to set.
Certain aftermarket air filters may cause a DTC to set.
Certain aftermarket air induction systems or modifications to the air induction system may cause a DTC to set.
Certain aftermarket exhaust system components may cause a DTC to set.
