QUESTION

Is the data of “Catalyst Temperature #12” 1000°C (1832°F)?

Yes No

Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

NOTE:

In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
