2001 Lexus LX470 Problems
RepairPal has identified the most common problems with the 2001 Lexus LX470 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
