Flow Too Low. Intermittent Fault

Checking Hoses, Cables And Terminals
- Check hose between pulsed secondary air injection system (PAIR) pump and pulsed secondary air injection system valve for pinching and damage.
- Check the vacuum hose with check valve between intake manifold and solenoid valve, and the hose between the solenoid valve and pulsed secondary air injection system valve for pinching and damage.
- Check pulsed secondary air injection system pump ground terminal 31/1 and pulsed secondary air injection system pump relay power supply terminals 1 and 3 for loose connections and an intermittent open-circuit.
- Check pulsed secondary air injection system pump connector for loose connections and an intermittent open-circuit.
- Proceed to: Fault-tracing Information section below.

Fault-tracing Information
For intermittent faults fault-tracing is not followed by a verification because the fault is not present at this moment.

- Do you want to repeat fault-tracing?

Yes:
^ Proceed to: Checking Hoses, Cables And Terminals section above.

No:
^ Operation done.
