Citroen Xsara Picasso - Engine warning light comes on | HELLA

If the error listed above is reported and error code P0410 is output, the cause may be a damaged secondary air pump filter.

Error code 'equivalent' to:

- P0410, 'Secondary air injection system malfunction, secondary air pump, secondary air valve, secondary air hoses'.

A damaged secondary air pump filter can result in internal dirt accumulation.

Furthermore, the secondary air control valve/solenoid valve may get stuck in the open position on vehicles that are cold started multiple times in a short period.

In this case, proceed as follows:

- Thoroughly clean the secondary air hose.

- Replace the secondary air pump.

- Check the functionality of the secondary air control valve/solenoid valve and replace it if necessary.
