P0607

DTC P0607 Control Module Performance

DESCRIPTION

DTC Detection 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. This is diagnosed by internal "mirroring" of the main and sub CPUs to detect processor errors. If outputs from the processors deviate from the standards, the ECM will illuminate the MIL and set a DTC immediately.

NOTE: An exhaust gas leak generates noise in the HO2S output. The ECM may interpret this as an HO2S transistor malfunction and set P0607.
