Monitor Description
WARNING: This page is about a different car, the 2010 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
The ECM continuously monitors its internal processors (CPUs) and Heated Oxygen (HO2) sensor transistors built into the ECM. 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 the DTC immediately.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0607 | When one of following conditions is met (1 trip detection logic):
|
|
| For Mexico models: ECM CPU error |
ECM |
NOTE:
An exhaust gas leak generates noise in the HO2 sensor output. The ECM may interpret this as an HO2 sensor transistor malfunction and set P0607.
