Keep the secondary air injection pump switching on command with the Standard Ignition Secondary Air Injection Relay / Air Pump Relay, part number RY-562. This Volvo 850 relay is a direct-fit replacement for the 1993-1997 Volvo 850. See the "Vehicles it fits" section for engine-level details.
The relay takes a low-current control signal and uses it to switch power to the secondary air injection (air) pump. The pump sends fresh air into the exhaust system as part of the vehicle's emissions controls. The part is listed under both names, secondary air injection relay and air pump relay.
Signs the air pump relay may need replacing: The air pump does not run, the air pump keeps running after it should shut off, or a check engine light appears with secondary air injection trouble codes. The pump, fuses and wiring can cause the same symptoms, so diagnose the circuit before replacing the relay.
