Lexus LX470 (2005-2007) Tire Pressure Monitoring System (TPMS) Sensor Guide
Dealing with a flashing TPMS light on your LX470? Here’s what you need to know before buying new sensors.
- A flashing TPMS light means a system fault, likely a dead sensor battery due to the vehicle's age.
- Always check the spare tire's pressure first, as it also has a sensor and is a common cause for the light.
- For best results, choose an OEM-quality aftermarket brand like Denso, Schrader, or Huf.
- It is most cost-effective to replace all five sensors at once to avoid repeated labor costs.
Is Your TPMS Light On? Understanding the Signs
The TPMS warning light on your LX470's dashboard can mean a few different things. Understanding the light's behavior is the first step to diagnosing the problem.
- Solid Light: A solid, continuously lit TPMS light usually means one or more of your tires, including the spare, is low on air. Check all five tires and inflate them to the pressure listed on the sticker inside your driver's door jamb.
- Flashing Light: A TPMS light that flashes for about a minute when you start the car and then stays on solid indicates a problem with the TPMS system itself. This is the most common sign of a dead sensor battery or a failed sensor. Since the sensors in a 2005-2007 model are now over 15 years old, battery failure is very common.
Don't Forget the Spare Tire
The Lexus LX470 of this generation includes a TPMS sensor in the spare tire. A low spare is a very common reason for the TPMS light to come on, so always make it the first thing you check.
Choosing the Right Aftermarket TPMS Sensor
When a sensor fails, you don't have to go to the dealership. High-quality aftermarket sensors are widely available and can save you a significant amount of money. However, quality can vary. Here’s a breakdown of reputable brands.
Tier 1: OEM Quality & Direct Fit
- Denso: Denso is a well-known original equipment manufacturer (OEM) for Toyota and Lexus. Choosing a Denso sensor (like part number 550-0103) is the closest you can get to the original part without the dealership price tag. They are pre-programmed and ready for installation.
- Schrader: Schrader is another top-tier OEM supplier for many car brands. Their sensors are known for reliability and are a solid choice for your LX470.
- Huf / BH Sens: Huf (also known as BH Sens) supplies OEM sensors and offers direct-fit, pre-programmed replacements that function just like the original parts.
Tier 2: Reliable Aftermarket Options
- Continental/VDO: VDO is the aftermarket brand of Continental, a major automotive supplier. They offer reliable sensors that are a good alternative to OEM.
- Bosch: Bosch offers universal programmable sensors that cover a wide range of vehicles. While they require programming with a special tool, they are a quality option.
Tier 3: Budget-Friendly Choices
- Dorman: Dorman is a popular aftermarket brand that offers a direct replacement for the LX470. While generally considered a budget-friendly option, ensure you are getting the correct pre-programmed part for your vehicle.
- Standard Motor Products (SMP): SMP offers both direct-fit and programmable sensors. They are a well-established aftermarket brand providing functional replacements.
Pro Tip: Replace Them All at Once
TPMS sensor batteries typically last 7-10 years. If one sensor has failed on your 2005-2007 LX470, the others are likely not far behind. To save on future labor costs, it is highly recommended to replace all five sensors at the same time, especially when you are already getting new tires.
Cost to Replace TPMS Sensors on a 2005-2007 LX470
The cost can vary depending on the brand of the sensor and the labor rates in your area. Installation requires the tire to be removed from the wheel, so labor is a significant part of the cost.
| Item | Estimated Cost (Per Sensor) |
|---|---|
| New Aftermarket Sensor | $37.00 - $76.97 |
| New OEM Sensor | $88 - $120 |
| Shop Labor (Install & Program) | $50 - $100 |
Frequently Asked Questions (FAQ)
Do I need a special tool to install new TPMS sensors?
While you can't physically install the sensor without a tire machine, the more critical part is programming. After the new sensors are installed, their unique ID codes must be registered with the vehicle's computer using a compatible TPMS scan tool or Toyota's Techstream software. Most tire shops can perform this service for you.
Can I use programmable/universal sensors?
Yes, brands like Bosch and Schrader offer programmable sensors. These must be programmed by the installer with a special tool to mimic the original sensor for your LX470 *before* installation. Direct-fit sensors from brands like Denso or Huf are simpler as they come pre-programmed from the factory.
Why is my TPMS light still on after getting new sensors?
This usually happens if the new sensor IDs were not correctly programmed into the vehicle's computer. The system needs to learn the new IDs to communicate with them. Take the vehicle back to the installer and ask them to perform the TPMS relearn procedure. Also, ensure the shop checked the Main/2nd switch in the glovebox, as having it on the wrong setting can cause issues.
Can I just ignore the flashing TPMS light?
While you can, it's not recommended. A flashing light indicates the system is not working, meaning you will not be alerted to a genuinely low tire. Many owners find the light annoying and some resort to covering it with tape or disabling the system entirely, but this defeats an important safety feature.
Are there any recalls for the TPMS on the 2005-2007 LX470?
No, there are no specific recalls or technical service bulletins (TSBs) from Lexus related to widespread TPMS sensor failure for this model range. Failures are typically due to the age and battery life of the original sensors.
