P0410 Volvo Description

An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.

Note:

1. Need to look up additional OBD-II Trouble Codes(DTC), use the search box. Enter the 5 character trouble codes in the search box and submit the search. You can repeat the search as many times as you need, one diagnostic code per search.
2. Don't assume a particular OBDii code means the same for other automotive manufacturers as there are many manufacturer specific codes in use.
3. If your trouble codes are for a different automotive, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other manufactures. The search only looks at OBD codes valid for the currently selected manufacturer.
4. This code is for reference only.
5. Help us improve CarObdCode.com. Tell us fix the code. Any information is appreciated. Thanks.
