2000 Lexus LX470 ProblemsLoud Vacuum Cleaner Noise on Cold Start
Drivers may hear a loud noise, much like a vacuum cleaner, coming from their engine on cold starts. This affects the 1998-2005 Lexus LX470.
The noise is from the secondary air pump, which sends hot air to the catalytic converter when the engine is cold. This allows the catalytic converter to clean exhaust better, and lower emissions while the engine is warming up.
Pump failure may result in:
- Check engine light
- OBD trouble code P1445
- Smog test failure
Fixing the issue involves removal of the intake manifold, and replacement of the secondary air pump.
The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.
Occasionally, the Check Engine Light is illuminated due to failures in the evaporative emission (EVAP) system. Our technicians tell us that proper diagnoses is generally required to confirm the exact fault causing the warning light to come on.
