2004 Lexus LX470 ProblemsCheck Engine Light due to EVAP system fault
The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.
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.

2004 Lexus LX470 RecallsSide Curtain Air Bags Deploy Unexpectedly
The side curtain air bags may deploy unexpectedly, resulting in possible occupant injury. Dealers will replace the air bag control module with one that has improved programming free of charge to resolve the concern.
A snap ring securing the steering shaft may disengage in the event of severe impact of the front wheel. If the snap ring is disengaged and the steering wheel is repeatedly turned to the lock position, over time, the steering shaft could become disconnected. This would result in loss of steering control, increasing the risk of a crash. Dealers will replace the snap ring with a newly designed one and install an additional device to prevent separation of the steering shaft. This recall is expected to begin on August 23, 2010.
