Internal Control Module O2 Sensor Processor Performance Bank 2
Generic · emissions
Data confidence85%
The control module detected a fault associated with the Internal Control Module O2 Sensor Processor Performance Bank 2 circuit or function; the stored code identifies the affected component rather than a single failure mode.
Symptoms
MIL illuminated
Possible increased fuel consumption
Possible unstable idle
Possible causes
Aged or contaminated oxygen sensor
Sensor heater circuit fault
Wiring or connector fault
Exhaust leak near the sensor
Mixture fault upstream of the sensor
Recommended checks
Read live sensor voltage/current and heater status
Inspect wiring and connectors
Check for exhaust leaks near the sensor
Check fuel trim values for upstream mixture faults

Data confidence94%
Ford documents P064E:00 (no sub type information) for its 2024-2025 gasoline-engine OBD monitor strategy as internal control module o2 sensor processor performance (bank 2). This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.

Frequently asked questions about P064E
What does P064E mean?
Internal Control Module O2 Sensor Processor Performance Bank 2. The control module detected a fault associated with the Internal Control Module O2 Sensor Processor Performance Bank 2 circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is P064E generic or manufacturer-specific?
P064E exists both as a generic OBD-II code (same meaning on every make) and with 1 manufacturer-specific interpretation(s): Ford. Always read it in the context of your vehicle.
Can TuningBot remove P064E at file level?
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
