I have a service engine soon light on and have hooked up an OBD11 reader to it and got code P0410 pertaining to a secondary air injection problem. hoses are fine, pump is new.


P0410 Oldsmobile - Secondary Air Injection System Malfunction

Possible causes: - Faulty Vacuum hoses damaged
- Faulty Air Pump inoperative
- Air bypass solenoid harness is open or shorted
- Air bypass solenoid circuit poor electrical connection
- Air bypass solenoid leaking/blocked or stuck open/closed
- Air diverter valve leaking/blocked or stuck open/closed

Tech notes: Visually inspect AIR pump and AIR bypass valve harness and connector, if connector are OK, then replaced AIR bypass valve.

When is the code detected? The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system.

Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
- Engine hesitation

P0410 Oldsmobile 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.

Abs code PO411


That is not an ABS system code, it is a powertrain fault code.P0411 - Secondary Air Injection System Incorrect Flow Detected, most common cause is a failed electric motor in the air injection pump.
The pump is under the hood.
Other Possible causes- Faulty Vacuum hoses damaged
- Air bypass solenoid harness is open or shorted
- Air bypass solenoid circuit poor electrical connection
- Air bypass solenoid leaking/blocked or stuck open/closed
- Air diverter valve leaking/blocked or stuck open/closed

Code po410


P0410 - Secondary Air Injection System Malfunction
Possible causes- Faulty Vacuum hoses damaged
- Faulty Air Pump inoperative
- Air bypass solenoid harness is open or shorted
- Air bypass solenoid circuit poor electrical connection
- Air bypass solenoid leaking/blocked or stuck open/closed
- Air diverter valve leaking/blocked or stuck open/closed

This is likely a pump problem caused by water being sucked into the secondary air injection pump under the hood.

How to change a 2000 ford explorer bypass hose?


You have to remove the tensioner assembly, not just the tensioner pulley, but the whole assembly, in order to access the plastic bypass hose.
Be very careful, as these pipes get old, the plastic becomes brittle, and possibly the flange end will break off and remain in the block when you remove the pipe, check the block opening carefully to remove all of the remaining flange.
Also, be very careful when removing the lover pipe nipple into the engine block, if you try to pry the tensioner assembly off the block, you will probably snap off the machined nipple that locates into the block, Ask me how I know!!! Good Luck, it can be done but you need to move carefully and deliberately. (by the way, a rebuilt tensioner assembly costs about $80 US, the pipe is about $6. New tensioner assembly comes with the pipe)
