The first hard freeze of the year is when TPMS failures spike. In my shop, we see it every November: Exeed owners rolling in with a blinking tire pressure light, convinced the sensor battery died. Sometimes it has. More often, it’s the sensor’s response time lagging in sub-zero conditions—a known issue with cheaper 315MHz units and aging OE parts.
Here’s what’s changed: Exeed’s factory TPMS systems, particularly on the TXL and VX models, were designed around a 433MHz communication frequency. That’s not a trivial spec. The higher frequency penetrates ice buildup on valve stems better and maintains signal integrity when tire pressure drops 4-6 PSI overnight in a cold snap. The aftermarket has finally caught up with proper 433MHz replacements that don’t cost dealership prices.
Temperature’s Real Effect on Sensor Accuracy
Let’s talk physics for a second. Tire pressure drops roughly 1 PSI for every 10°F decrease in ambient temperature. A sensor that reads 32 PSI at 70°F will show 29 PSI at 40°F. That’s within normal operating range, but many Exeed drivers panic and over-inflate. The sensor itself isn’t wrong—it’s reading actual pressure. The problem is driver interpretation.
But there’s a second, less obvious temperature effect: battery performance. TPMS sensor batteries are rated for 5-7 years, but cold weather accelerates voltage drop. A sensor entering its fifth winter with marginal battery voltage will start transmitting intermittently. The vehicle’s receiver might get a reading every 90 seconds instead of every 10. That’s when false warnings appear.
The BH-Sens BL-ST-013 unit we’ve been stocking addresses both issues. It’s a pre-programmed, clamp-in sensor running at 433MHz with a genuine Baolong Technology board inside. Cold-start transmission time is noticeably quicker than generic aftermarket units—roughly half a second faster in our bench tests at 20°F. That matters when you’re pulling out of a driveway at 6 AM in January.
Winter Prep: What Exeed Owners Should Actually Do
Before recommending any sensor replacement, here’s the practical checklist I run through with Exeed customers:
- Check valve stem condition: Clamp-in sensors have rubber gaskets that harden in cold weather. Cracks mean slow leaks that read as pressure drops.
- Verify the sensor’s pressure range: The BL-ST-013 covers 0-87 PSI, which is overkill for passenger Exeed models but useful if you’re running winter tire setups with different pressure requirements.
- Test signal strength at cold start: Park the car overnight, then check the TPMS display within 30 seconds of startup. Delayed readings indicate a weak transmitter.
- Replace in axle pairs: If one sensor fails, the opposite wheel’s sensor is usually close behind. Doing both saves a second trip to the shop.
The BL-ST-013 fits 17 Exeed, Chery, and Hima applications with OE numbers 802000277AA and 802000589AA. That cross-compatibility makes it a sensible stock item for shops serving multiple Chinese-brand vehicle owners.
Summer Heat: The Other Extreme
Winter gets the attention, but summer kills more TPMS sensors. Underinflated tires generate excessive heat, and that heat cooks the sensor’s internal battery. I’ve pulled sensors from Exeed VX models in July that were literally deformed from sustained high temperatures.
The 433MHz frequency helps in summer too. Higher frequency sensors use less power per transmission, which means less internal heat generation. It’s a small margin, but over 100,000 miles, it extends service life noticeably.
One thing to note: this sensor is pre-programmed. You won’t need a TPMS tool to clone the original sensor’s ID. That saves about 20 minutes of labor per wheel—and eliminates the risk of programming errors that can trigger the ABS light on some Exeed variants.
Storage and Longevity for Spare Sensors
If you’re a shop stocking spares or a DIY owner keeping a backup, storage conditions matter more than most people think. TPMS sensors are sensitive to:
- Extreme heat: Don’t leave them in a tool shed or car trunk during summer. Ambient temps above 140°F shorten battery life.
- Direct sunlight: UV degrades the rubber housing and can cause the seal to fail prematurely.
- Stacking heavy items on top: The valve stem is brass and can bend under pressure.
Store them in a cool, dark place—ideally between 50-80°F. The BL-ST-013 weighs about an ounce, so it’s small enough to keep in a parts drawer rather than on a shelf where it might get crushed.
The Bottom Line for Exeed Owners
If your Exeed is approaching 5 years old or you’re seeing intermittent TPMS warnings in extreme temperatures, don’t default to a dealership replacement. The BL-ST-013 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Chery, Exeed, Hima | OE# 802000277AA, 802000589AA from BH-Sens delivers OEM-equivalent performance at roughly a third of the dealer price. It’s a direct fit for the 17 most common Exeed applications, and the 433MHz frequency matches factory receiver expectations.
We’ve sold these through two full seasonal cycles now, and the return rate sits under 1%. For a TPMS sensor, that’s excellent.

Buying Takeaway
For shops: stock the BL-ST-013 as your default Exeed TPMS replacement. It covers most of the Chinese-brand vehicles you’ll see in a given year, and the pre-programmed format speeds up installs.
For owners: if you’re doing winter tire swaps or prepping for a seasonal road trip, this is the sensor to keep in your glovebox. One replacement unit covers all four wheels if you have the factory TPMS tool—or just have your local shop handle it. The price point makes stocking a spare painless.
The seasonal cycle will always stress TPMS systems. The difference is whether your sensor is engineered to handle it. The BL-ST-013 is.
