Detection Condition

PCM monitors input voltage from front HO2Ss when engine speed is more than 1500 RPM and ECT is more than 158°F (70°C). If input voltage from front HO2Ss remains less or more than 0.45 volt for 33.6 seconds, PCM determines there is no front HO2S inversion and DTC is set. This is a continuous monitor. MIL is illuminated if PCM detects malfunction in two consecutive drive cycles.
