Flow Too Low. Intermittent Fault

Checking Hoses And Pipes
- 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 31/44 and pulsed secondary air injection system pump relay power supply terminal C2 for an intermittent open-circuit.

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:
^ Return to Checking Hoses And Pipes section above.

No:
^ Operation done.
