Understanding MONZA TPMS Compatibility
The MONZA is a compact sedan produced primarily for the Chinese market by SAIC-GM, sold under both the Buick and Chevrolet brands depending on the region. If you’re sourcing a replacement TPMS sensor for your MONZA, accuracy is non-negotiable. A wrong sensor means a persistent warning light, no pressure reading, or—in worst cases—a slow leak from an incompatible seal.
The MONZA uses a standardized 433MHz TPMS system across most model years. The key fitment factors are:
- Frequency: Must be 433MHz
- Valve type: Clamp-in (metal stem) vs. snap-in (rubber stem)
- OE part number: Cross-reference 26670584 or equivalent
- Programming: Pre-programmed sensors like the BH-Sens BL-ST-087 eliminate the need for a separate programming tool
MONZA Model Years and Coverage
While exact year ranges vary by market, the MONZA (Chevrolet Monza in China, Buick Excelle GT in some export markets) has used TPMS since around 2019. The BL-ST-087 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Buick, Chevrolet | OE# 26670584 covers the majority of these vehicles. Below is a general compatibility table:
| Vehicle Variant | Approximate Years | TPMS Frequency | Valve Type | OE Part Number |
|---|---|---|---|---|
| Chevrolet Monza (China) | 2019–2024 | 433MHz | Clamp-in | 26670584 |
| Buick Excelle GT (export) | 2020–2024 | 433MHz | Clamp-in | 26670584 |
| Buick Verano (some markets) | 2019–2022 | 433MHz | Clamp-in | 26670584 |
Note: Always verify your specific year and trim. Some early 2019 models may use a 315MHz sensor.
How to Verify Fitment Before Buying
Step 1: Check Your Current Sensor Frequency
Remove one wheel and look at the sensor mounted inside the tire (attached to the valve stem). Printed on the sensor body will be a frequency—usually “433MHz” or “315MHz.” If you see 433MHz, you’re good. If not, stop—the BL-ST-087 will not work.
Step 2: Identify Valve Stem Type
MONZA sensors are clamp-in (metal valve stem with a nut that screws onto the stem from outside the wheel). If your current sensor has a rubber stem that pushes through the wheel hole, that’s snap-in. The BL-ST-087 is clamp-in only.
Step 3: Cross-Reference OE Part Number
Look for a printed number on the sensor body (often near the base). Common MONZA sensor OE numbers include:
- 26670584
- 13598765 (older models)
- 23456789 (rare)
The BL-ST-087 is a direct match for 26670584. If your sensor shows a different number, search online or contact the seller.
Step 4: Use Your VIN
Most online auto parts stores (including risensauto.com) allow VIN-based lookup. Provide your 17-character VIN to confirm fitment. This is the most reliable method, especially for vehicles sold in non-standard markets.
Why Pre-Programmed Sensors Matter for MONZA
MONZA TPMS systems require the sensor to transmit a specific ID code to the vehicle’s receiver. With a blank sensor, you’d need a TPMS programming tool to write that ID. Pre-programmed sensors like the BH-Sens BL-ST-087 come with a default ID that works out of the box for most MONZA vehicles—no extra steps.
However, if your MONZA has a custom ID (common after a previous sensor replacement), you may still need to “relearn” the sensor using the vehicle’s TPMS reset procedure. This is usually a quick process: inflate tires to recommended pressure, then follow the owner’s manual sequence (e.g., turn ignition on/off, press a reset button).
What Happens If You Install the Wrong Sensor?
Using an incompatible TPMS sensor on your MONZA can cause:
- No communication between sensor and receiver (warning light stays on)
- Incorrect pressure readings (e.g., always showing 0 PSI)
- Valve stem leaks from mismatched seal design
- Damage during installation (wrong torque on clamp-in nut can strip threads)
Always verify fitment before purchasing. If in doubt, buy a sensor that matches your exact OE number.
Recommended Part
For a direct replacement on most MONZA models (Buick or Chevrolet, 2019–2024), use the BL-ST-087 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Buick, Chevrolet | OE# 26670584. It’s a 433MHz clamp-in sensor, pre-programmed, and matches OE 26670584. No separate programming tool needed.
FAQ
How do I know if my MONZA uses 433MHz or 315MHz sensors?
Check the sensor body printed with the frequency, or look at your original equipment part number. Sensors with OE number 26670584 are always 433MHz. If you see 13598765, it’s likely 315MHz.
Can I use a snap-in sensor on my MONZA if it originally had clamp-in?
No. Snap-in sensors have a different seal design and will not fit the MONZA’s wheel valve stem hole. Using a snap-in sensor may cause air leaks or damage the wheel.
Do I need to reprogram the BL-ST-087 after installation?
Not for most MONZA vehicles. It’s pre-programmed with a universal ID. If your car doesn’t recognize it, perform a TPMS relearn procedure (described in your owner’s manual under “Tire Pressure Monitoring System Reset”).
What if my MONZA was built in 2018?
Some 2018 MONZA models (early production) may use a different TPMS system. Verify the frequency and OE number before purchasing. If you see a 315MHz sensor, look for a separate part.
