EC-678 [QG (WITHOUT EURO-OBD)] DTC P0132, P0152 HO2S1 (A/T MODELS) 5. Touch “RECORD” on CONSULT-II screen. 6. Check the following. ● “HO2S1 MNTR (B1)/(B2)” in “DATA MONITOR” mode ● “HO2S1 (B1)/(B2)” voltage goes above 0.6V at least once. ● “HO2S1 (B1)/(B2)” voltage goes below 0.3V at least once. ● “HO2S1 (B1)/(B2)” voltage never exceeds 1.0V. CAUTION: ● Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7 ● Before installing new oxygen sensor, clean exhaust system threads using Oxygen Sensor Thread Without CONSULT-II 1. Start engine and warm it up to normal operating temperature. 2. Set voltmeter probes between ECM terminal 35 [HO2S1 (B1) signal] or 36 [HO2S1 (B2) signal] and 3. Check the following with engine speed held at 2,000 rpm con- ● The voltage fluctuates between 0 to 0.3V and 0.6 to 1.0V ● The maximum voltage is over 0.6V at least one time. ● The minimum voltage is below 0.3V at least one time. ● The voltage never exceeds 1.0V. 1 time: 0 - 0.3V → 0.6 - 1.0V → 0 - 0.3V 2 times: 0 - 0.3V → 0.6 - 1.0V → 0 - 0.3V → 0.6 - 1.0V CAUTION: ● Discard any heated oxygen sensor which has been dropped SEF646Y SEF647Y SEF648Y MBIB0019E |
