If you’ve had a 2021 or newer Chery Tiggo 8 Pro roll into your bay with a blinking tire pressure light, you already know the drill. The OE sensor works—until it doesn’t. And when it fails, the customer doesn’t care about the CAN bus protocol or the battery soldering. They just want the light off and the car safe.
But here’s where the aftermarket gets murky. You pull up a listing for a “BL-ST-013” and see a wall of specs: 433MHz, IP67, clamp-in, pre-programmed. If you’re not fluent in TPMS datasheet speak, you might grab the wrong part and eat the labor cost. Let’s decode the numbers that actually matter for BL-ST-013 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Chery, Exeed, Hima | OE# 802000277AA, 802000589AA applications—and why this particular BH-Sens unit simplifies your life.
Reading the Three Specs That Decide Fitment
Frequency: 433MHz Isn’t a Suggestion
Chery’s global platforms—Tiggo, Arrizo, Exeed, and the newer Hima line—have used both 315MHz and 433MHz across different model years. The BL-ST-013 is locked to 433MHz. That’s the carrier frequency the vehicle’s receiver module listens on.
In practice, this means two things. First, you cannot install this sensor on a 315MHz vehicle and expect it to wake up. The RF signal won’t be heard, period. Second, pre-programmed at 433MHz means it transmits using the standard Chery data frame—including sensor ID, pressure, temperature, and battery status—without needing a cloning tool that speaks the manufacturer’s proprietary protocol.
Pro tip: Before you quote a job, check the tire pressure placard or the old sensor’s part number. If the original is stamped 802000277AA, you’re on 433MHz. If it’s 802000589AA, same story—those are the two OE references this BH-Sens unit replaces.
IP67: Water and Dust Resistance That Matches OE
IP67 is one of those ratings that gets thrown around loosely, but for a clamp-in sensor mounted inside the wheel, it’s the difference between a five-year service life and a corroded battery terminal at month eight.
The “6” means total dust ingress protection—no particulate gets inside the housing. The “7” means the sensor survives immersion in water up to one meter for 30 minutes. For a TPMS sensor, that covers pressure washing, puddle splashes, and the occasional deep-water crossing on a Tiggo 4 that’s been driven harder than Chery intended.
Here’s the real-world nuance: IP67 doesn’t guarantee performance after a tire shop mounts it incorrectly. If the valve core isn’t torqued to spec, the seal fails regardless of the housing rating. But with BL-ST-013’s sealed electronics, the typical failure mode shifts from “water got in” to “battery died at year six or seven.” That’s a predictable replacement interval, which is exactly what you want when quoting fleet maintenance.
Connector Type and Clamp-In Design: The Mounting Reality
The BL-ST-013 is a clamp-in sensor, meaning it secures to the wheel via a metal valve stem and a nut from the outside. This is the standard for Chery’s aluminum wheels. You’ll need a torque wrench rated for 4.0–6.0 Nm (about 35–53 in-lb) on the valve nut—over-torquing strips the brass threads, and under-torquing causes an air leak that sounds like a TPMS failure but isn’t.
The “pre-programmed” designation matters more than most techs realize. This sensor ships with a fixed ID that can be learned by the vehicle using the standard OBD-II relearn procedure on most Chery models. No TPMS tool that speaks the proprietary Shanghai Baolong protocol? Not a problem. You trigger the learn mode, hold a magnet near the valve stem, and the RF signal pairs the sensor.
A quick reality check: If the customer’s vehicle is a 2019–2022 Exeed TXL, the relearn procedure is the same. This is one of the few aftermarket sensors that covers multiple brands under the Chery umbrella without needing separate SKUs.
Why the BH-Sens Build Quality Cuts Down Comebacks
Baolong Technology—the parent brand behind BH-Sens—isn’t a no-name clone shop. They’re an OE supplier for several Chinese automakers, which means the BL-ST-013 doesn’t just meet the electrical specs; it’s built on the same production lines that feed Chery’s factory. For a shop owner, that translates into fewer warranty callbacks.
The unit weighs around one ounce, which is negligible for wheel balance. But the housing is a glass-filled nylon composite that handles temperature swings from -40°C to +125°C. That’s important if you’re in a climate where summer asphalt hits 60°C and winter nights drop to -30°C. The internal battery is rated for a 5–7 year service life under normal driving conditions—about 10,000 hours of active transmission.
Fitment Coverage You Should Know
The BL-ST-013 lists 17 vehicle applications across Chery, Exeed, and Hima. Here’s the practical breakdown:
- Chery Tiggo series (4, 5, 7, 8, 8 Pro) — all use 433MHz clamp-in sensors on their standard 17–19 inch wheels.
- Exeed TXL and VX — same TPMS platform, same relearn procedure.
- Hima (the budget sub-brand) — shares Chery’s electrical architecture, so the sensor carries over.
The one caveat? If you’re working on a Chery built for the Chinese domestic market with a 315MHz receiver, this sensor won’t work. Always verify the old sensor’s frequency stamp before ordering.
The Bottom Line for Parts Managers and Independent Techs
You’re not buying a sensor; you’re buying a solution to a diagnostic headache. The BL-ST-013 from BH-Sens checks the three boxes that matter: correct frequency, OE-grade sealing, and pre-programmed IDs that accept standard relearn procedures. It’s not the cheapest TPMS sensor on the market, but it’s priced well below a dealer OE part, and it eliminates the “clone the old ID” step that requires a $400 programming tool.
One final note on purchasing: if you’re stocking for a shop that sees multiple Chinese-brand vehicles, grab a small batch rather than single units. These sensors have a shelf life of about five years unopened (battery drains slowly), but they move fast enough that you won’t sit on dead stock. And when a 2023 Tiggo 7 rolls in with a cracked valve stem, having the part on hand turns a two-day wait into a same-day fix—which is how you earn a repeat customer.
