Why Fitment Matters for Chevrolet TPMS Sensors
Chevrolet vehicles use direct TPMS sensors mounted inside the wheel. If you install the wrong sensor—wrong frequency, wrong protocol, or wrong valve type—the system won’t sync. The TPMS light stays on, and you’ll waste time and money on returns. For the BL-ST-048 (433MHz, clamp-in), the most common mistake is buying a 315MHz sensor for a 433MHz system, which happens frequently on older Chevrolet trucks.
Understanding Chevrolet TPMS Frequencies
Chevrolet used two main frequencies:
- 315MHz – Older models (roughly 2000–2006, some early 2007s)
- 433MHz – Most models from 2007 onward (Silverado, Tahoe, Suburban, Equinox, Malibu, Cruze)
The BL-ST-048 operates at 433MHz. If your Chevrolet is a 2008–2020 model, it almost certainly uses 433MHz. But exceptions exist: some 2007–2008 Chevy Impala and Cobalt models still used 315MHz. Always check.
Compatible Chevrolet Models for BL-ST-048 (OE# 13530661)
Based on the OE numbers (13530661, 13533166, 13538565, 13538566, 13538761, 13549707), this sensor covers these Chevrolet platforms:
| Chevrolet Model | Year Range | Notes |
|---|---|---|
| Silverado 1500 | 2007–2020 | 433MHz, clamp-in valve |
| Tahoe / Suburban | 2007–2020 | Same platform as Silverado |
| Equinox | 2010–2020 | Verify valve type (clamp-in vs. snap-in) |
| Malibu | 2008–2020 | 433MHz after 2008 |
| Cruze | 2011–2020 | European protocol, but compatible |
| Traverse | 2009–2020 | Often requires relearn after install |
| Colorado / Canyon | 2015–2020 | 433MHz system |
Note: The BL-ST-048 is pre-programmed and cloneable. It mirrors the original sensor’s ID, so no TPMS relearn tool is needed in many cases—just install and drive. Some Chevrolet models (2015+ Silverado, 2016+ Tahoe) may still require a relearn procedure using a TPMS tool or the vehicle’s menu.
How to Verify Fitment Before Buying
Follow these four steps to avoid a mismatch:
1. Check Your Original Sensor’s OE Number
Remove the wheel, look at the sensor body. The OE number is printed on the side (e.g., 13530661, 13538565). If you can’t find it, check the valve stem—Chevrolet often stamps the number there. Match it against the BL-ST-048 OE list: 13530661, 13533166, 13538565, 13538566, 13538761, 13549707.
2. Confirm the Frequency
If you don’t have the sensor yet, check your vehicle’s build date or VIN. For 2008+ Chevrolet models, the frequency is almost always 433MHz. You can also call a dealership with your VIN—they’ll tell you the exact frequency and OE number.
3. Check Valve Type: Clamp-in vs. Snap-in
The BL-ST-048 is a clamp-in sensor (nut and metal stem). Chevrolet trucks and SUVs (Silverado, Tahoe, Suburban) use clamp-in sensors. Some Equinox and Malibu models use snap-in sensors (rubber stem). If your vehicle uses snap-in, this sensor won’t fit physically.
4. Verify Tire Size and Pressure Ranges
This sensor is pre-programmed with a standard pressure range (typically 30–40 PSI). For heavy-duty Chevrolet models (2500/3500 series) that run higher pressures (50–80 PSI), this sensor may not be compatible. Stick to the 1500 series and standard SUV/CUV models.
Common Chevrolet TPMS Fitment Pitfalls
- Mixing frequencies: Installing a 315MHz sensor on a 433MHz system will fail immediately. The TPMS light will flash and stay on.
- Wrong valve type: A clamp-in sensor won’t fit a snap-in valve hole (and vice versa). Always match the physical design.
- Relearn issues: Even if the sensor is compatible, some Chevrolet models (2015+ with Autoloc protocol) require a TPMS relearn tool to register the new sensor. The BL-ST-048 is cloneable, which simplifies this—but if you’re replacing all four sensors, you may need to clone the original IDs or perform a relearn.
Recommended Part
For most Chevrolet 2007–2020 models with 433MHz systems, the BL-ST-048 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Buick, Cadillac, Chevrolet, Nevo | OE# 13530661, 13533166, 13538565 is a direct-fit replacement. It matches OE specs, is pre-programmed, and clones easily. If you’re unsure about your specific year or trim, contact us with your VIN—we’ll confirm compatibility within hours.
FAQ
How do I know if my Chevrolet uses 433MHz or 315MHz TPMS?
Check the build date. If your Chevrolet was manufactured after mid-2007, it’s likely 433MHz. You can also look at the original sensor—if the OE number is 13530661, 13533166, or 13538565, it’s 433MHz. If you see a 257… series number (like 25776878), it’s 315MHz.
Will the BL-ST-048 work on my 2012 Chevrolet Silverado 2500HD?
It may work, but only if your Silverado 2500HD uses standard tire pressures (40–50 PSI). Some heavy-duty trucks run higher pressures that exceed this sensor’s range. Check your owner’s manual or the door jamb sticker for recommended tire pressure. If it’s above 50 PSI, look for a heavy-duty TPMS sensor.
Do I need a TPMS relearn tool after installing the BL-ST-048?
Not always. Because the sensor is pre-programmed and cloneable, it can copy the original sensor’s ID. If you replace a single sensor and clone the ID, the system will recognize it immediately. If you replace all four sensors without cloning, you’ll need a relearn tool (or the vehicle’s built-in relearn procedure in the driver information center).
Can I install a BL-ST-048 on a 2016 Chevrolet Equinox with snap-in sensors?
No. The BL-ST-048 is a clamp-in sensor with a metal stem and nut. The Equinox (2010+) uses a snap-in rubber stem sensor. You would need a snap-in 433MHz sensor instead. Always match the physical valve type before buying.
