C0210 on Toyota by model: symptoms, diagnosis and fix
On the 2000-2005 Echo, the rear wheel bearing is built into the rear hub, and Toyota's parts catalog lists it only as a complete hub-and-bearing assembly. As the bearing wears, it makes a hum or growl from the rear that gets louder as the car speeds up. Owners have reported this at high mileage: one said the rear hub bearings on a 2003 Echo went out at about 200,000 miles, and a 2005 owner at 156,000 miles was told a rear-end hum was likely a rear wheel bearing. Unevenly worn tires and worn brakes can make a similar sound, so check the bearing before replacing parts. Don't keep driving on a failing bearing. It builds heat and can eventually lock up the wheel.
Common Symptoms
- Humming or droning noise from the rear that rises with road speed
- Noise may get worse when turning
- Rough or grinding sound when the raised rear wheel is spun by hand
- Play in the rear wheel when rocked at 12 and 6 o'clock
- Growling noise from the rear at highway speed
How to Fix
Check first: on a test drive, listen for a hum that rises with road speed and may get worse in turns. Then raise each rear wheel, rock it at 12 and 6 o'clock to feel for play, and spin it by hand while you listen for roughness or grinding. Having no play does not rule out a bad bearing, so the noise when you spin the wheel matters too. Also look at tire wear and the brakes, because both can sound like a bearing. Fix: replace the complete rear hub-and-bearing assembly on the noisy side. Toyota does not list the rear bearing on its own. Toyota's current part numbers for the 2004 Echo are 42410-52021 (driver side) and 42450-52021 (passenger side, noted for ABS-equipped cars). They supersede 42410-52020 and 42450-52020. Confirm the part against your VIN, because ABS and non-ABS cars may take different hubs. The front bearings are a separate job: they are pressed into the spindle and usually need a special puller or press. We found no recall or Toyota service bulletin for this. It is a normal wear repair.

Owner tips & cautions
- TipReplace both rear bearings at the same time — when one fails at 70,000 miles, the other is typically close behind
- WarningDo not drive on a bad wheel bearing — a seized bearing can lock the rear wheel at speed, causing loss of vehicle control

Frequently asked questions
What does C0210 mean on a Toyota?
C0210 stands for "Vehicle Speed Signal Missing." C0210 is a chassis code indicating the vehicle speed signal is missing, meaning a control module (often the ABS/brake or stability system) is not receiving the expected vehicle speed information. Vehicle speed is derived from wheel speed sensors or transmission output sensors and is shared across systems; when that signal drops out, this code sets. Symptoms can include a non-working speedometer, disabled ABS/traction/stability control, transmission shift issues, or cruise control loss. It points to a speed sensor, its wiring, or the network carrying the signal rather than a brake friction problem. On Toyota it is documented across 1 model: Echo.
What are the most common causes of C0210?
The most common causes of C0210 are: Faulty vehicle/wheel speed sensor, Damaged, corroded, or loose speed sensor wiring/connector, Faulty transmission output/vehicle speed sensor, Open or shorted speed signal circuit, ABS or control module fault not relaying the signal, Loss of communication on the data bus carrying speed data, Damaged sensor tone/reluctor ring. The specific cause varies by vehicle.
How much does it cost to fix C0210 on a Toyota?
Published repair estimates on Toyota range from $200 to $500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
