• In the DTC check, it is very important to determine
whether the problem indicated by the DTC either: 1)
still occurs, or 2) occurred in the past but has returned
to normal. In addition, the DTC should be compared
to the problem symptom to see if they are related. For
this reason, DTCs should be checked before and after
confirmation of symptoms (i.e., whether or not
problem symptoms exist) to determine current system
conditions, as shown in the flowchart below.
• Never skip the DTC check. Failing to check DTCs
may, depending on the case, result in unnecessary
troubleshooting for systems operating normally or
lead to repairs not related to the problem. Follow the
procedures listed in the flowchart in the correct order.

DESCRIPTION
The ECM continuously monitors its internal processors (CPUs), A/F sensor transistors and heated oxygen
sensor (HO2S) transistors. This self-check ensures that the ECM is functioning properly. These are
diagnosed by internal "mirroring" of the main and sub CPUs to detect the processors error. If outputs from
the processors deviate from the standards, the ECM will illuminate the MIL and set a DTC immediately.

INSPECTION PROCEDURE
(a) Allow the engine to idle.
(b) Check for exhaust gas leak around the heated oxygen
sensor.

DESCRIPTION
The ECM continuously monitors its main and sub CPUs. This self-check ensures that the ECM is
functioning properly. If outputs from the CPUs are different and deviate from the standards, the ECM will
illuminate the MIL and set a DTC immediately.
The ECM also monitors the cruise control cancel circuit. If this circuit malfunctions, the ECM will set a
DTC immediately (MIL is not illuminated).
NOTICE:
First check for an exhaust gas leak around the HO2S if P0606 is present. An exhaust gas leak
generates noise in the HO2S output. The ECM may interpret this as an HO2S transistor
malfunction.
