DTC P2096:00: Notes

DTC P2096:00 (MZR 1.5) DETECTION CONDITION AND POSSIBLE CAUSES

DTC P2096:00	Target A/F feedback system too lean
DETECTION CONDITION	The PCM monitors the target A/F fuel trim when under the 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. Diagnostic support note This is a continuous monitor (fuel system). The MIL illuminates if the PCM detects the above malfunction 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 first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	HO2S malfunction Exhaust gas leakage HO2S malfunction IAT sensor malfunction Erratic signal to PCM APP sensor signal malfunction ECT sensor No. 1 signal malfunction MAF sensor signal malfunction TP sensor signal malfunction VSS signal malfunction Related connector or terminals malfunction Related wiring harness malfunction A/F sensor malfunction Exhaust gas leakage A/F sensor malfunction MAF sensor malfunction Air suction in intake-air system Fuel supply system malfunction or insufficient fuel line pressure Fuel leakage from fuel system Pressure regulator malfunction (built-into fuel pump unit) Fuel pump malfunction Improper operation of fuel injector Fuel injector related wiring harness malfunction Fuel injector malfunction Ignition system malfunction Ignition coil malfunction Ignition coil related wiring harness malfunction Spark plug malfunction Insufficient engine compression ECT sensor No. 1 malfunction PCM malfunction
