What are Some Common Problems with Lexus LX 470?
Your LX 470 might've gone full-size on the quintessential Lexus combination of luxury and capability. However, the SUV wasn't without issues during its career in the late 1990s and early 2000s. Luckily, they're easy to diagnose if you know what signs to look for.
Here are three of the commonest, and what to do about them.
1. EVAP System Faults
If the Check Engine light is on in your LX 470, then most likely, a bad charcoal canister or a loose or worn gas cap is affecting the evaporative emission (EVAP) system. This is a known issue for models from between 2002 and 2007 with 150,000 miles or fewer on their odometers. You'll probably need to replace one, the other, or both, depending on what turns out to be the problem.
2. Defective Exhaust Parts
If the engine in your LX 470 makes a loud, vacuum-like noise when you start it; if the Check Engine light comes on; if inspection feeds back error code P1445; and if the SUV fails a smog test, then most likely, the secondary air pump feeding to the catalytic converter has failed. This is a known issue for models from between 1998 and 2005. You'll have to take the intake manifold, out, put a new air pump in, and reinstall the manifold.
3. Bad Sensors
Another reason why the Check Engine light may be on in your LX 470 is a faulty oxygen sensor. This is a known issue for models from between '98 and 2000. Run an inspection to be sure the sensor's the problem; if it is, you'll have to replace it.
