DTC P0606 ECM / PCM Processor

DESCRIPTION

DTC Setting Condition:

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

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.
