DTC P2096: Notes

DTC P2096 DETECTION CONDITION AND POSSIBLE CAUSES

DTC P2096	Target A/F feedback system too lean
DETECTION CONDITION	The PCM monitors the target A/F fuel trim while under target A/F feedback control. If the fuel trim is more than the specification, the PCM determines that the target A/F feedback system is too lean. Rear HO2S sensor voltage is more than 0.1 V Diagnostic support note This is a continuous monitor (Fuel system). The MIL illuminates if the PCM detects the above malfunctioning condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA is available. DTCs are stored in the PCM memory.
POSSIBLE CAUSE	Exhaust gas leakage Rear HO2S malfunction IAT sensor malfunction ECT sensor malfunction Air suction in intake-air system Front HO2S malfunction MAF sensor malfunction Insufficient fuel line pressure Fuel pressure sensor malfunction Relief valve, (built-in fuel delivery pipe) malfunction Spill valve control solenoid valve (built-in high pressure fuel pump) malfunction High pressure fuel pump malfunction Fuel pump malfunction Leakage fuel Improper operation Ignition system Insufficient engine compression Fuel injector malfunction PCM malfunction
