DescriptionINFOID:0000000001670924
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.
DTC LogicINFOID:0000000001670925
DTC DETECTION LOGIC
Under the condition in which the heated oxygen sensor 1 signal is
not input, the ECM circuits will read a continuous approximately
0.3V. Therefore, for this diagnosis, the time that output voltage is
within 200 to 400 mV range is monitored, and the diagnosis checks
that this time is not inordinately long.
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11V at idle.
