Electrical Control Fault:
Fault code P0070 indicates the engine control module has detected incorrect operation of the pump motor relay. This is an electrical fault, not a failed sensor.
What Does Volvo Fault Code P0070 Mean?
On Volvo vehicles, fault code P0070 means the ECM is commanding a pump motor relay but is not seeing the correct electrical response. This usually relates to auxiliary pumps, emissions systems, or engine support systems depending on model and engine variant.
