DTC P0607: Control Module Performance [08/2019 - ]: Description

The ECM continuously monitors its internal processors (CPUs) and heated oxygen sensor (HO2S) transistors. This self-check ensures that the ECM is functioning properly.

DTC Code	DTC Detection Condition	Trouble Area
P0607	ECM CPUs malfunction HO2S transistors malfunction	Exhaust gas leak HO2S ECM

NOTE:

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