Frequently asked questions about P2078
What does P2078 mean?
Intake manifold air control actuator position sensor/switch - circuit high. The control module detected that the signal in the Intake manifold air control actuator position sensor/switch circuit stayed above the expected operating range.
Is P2078 generic or manufacturer-specific?
P2078 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove P2078 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.
