Circuit/System Verification
- Ignition OFF for 8 hours or greater.
- Ignition ON, observe the scan tool IAT Sensor and ECT Sensor parameters. The IAT, ECT, and ambient temperatures should be within 15°C (27°F) of each other.
- Engine running, observe the scan tool IAT Sensor parameter. The reading should be between -39 to +120°C (-38 to +248°F) depending on the current ambient temperature and the vehicle operating conditions.
- Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
