Code C1222 Description
The C1222 code indicates a speed wheel mismatch, which means that the vehicle's onboard computer system has detected a discrepancy in the speed of one or more wheels compared to the others. This issue can have significant implications for the vehicle's performance and safety. The speed wheel sensors are crucial components of the vehicle's anti-lock braking system (ABS) and traction control system. They provide real-time data on the speed of each wheel to the computer, allowing it to make adjustments to prevent skidding and maintain stability during braking and cornering.
Common Causes of C1222
- Faulty speed wheel sensors
- Damaged wiring or connectors
- Malfunctioning ABS module
- Issues with wheel bearings or hub assemblies
- Incorrect tire sizes or inflation levels
Symptoms of C1222
- ABS warning light or traction control light illuminated on the dashboard
- Traction control system engaging unexpectedly
- Uneven braking or pulling to one side during braking
- Reduced stability or handling during driving
How to Fix C1222
- Diagnose the specific wheel or wheels causing the mismatch using a diagnostic scanner.
- Inspect the speed wheel sensors, wiring, connectors, and ABS module for any signs of damage or malfunction.
- Replace any faulty speed wheel sensors, repair damaged wiring or connectors, or replace the ABS module as needed.
- Test drive the vehicle to ensure the issue has been resolved and recalibrate the ABS and traction control systems if necessary.
Cost to Fix C1222
The cost of repairing a speed wheel mismatch can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, replacing a faulty speed wheel sensor can cost between $100 to $200 per sensor, while repairing wiring or connectors may range from $50 to $150. If the ABS module needs to be replaced, the cost can be higher, typically ranging from $200 to $600. Labor costs can add to the overall repair bill, with rates typically ranging from $80 to $150 per hour. It's advisable to consult with a professional mechanic or auto repair shop for a more accurate cost estimate based on your vehicle's make and model.

Discuss the causes and fixes for C1222 OBDII Code
-
2001 Mustang Cobra DOHC w/ 67,000 miles. The only lights that flashed on and then off were the "Traction Control", then the "ABS" light.
-
The means that one (or more ) of the wheel is turning either slower of faster that the other ones. You could start by checking the tires, make sure all the tires are the same size and are in good condition. If the all the tires are OK, then of the wheel sensors is not reading properly.
-
You need an special OBDII scanner that can access the ABS system and read the signal from each sensor. Did you checked the tires condition and pressure?
-
I only have a "CarMD" and I don't see any mention of reading ABS; but as far as the tires go, it has excellent tires and I check the tire pressure regularly. But more importantly, my car was built before they (Ford) installed tire pressure monitoring. I did buy an a Ford Rotunda "VCMII" pass-thru; so I could re-program my computer (using the rented software from Ford). Unfortunately, I was not able to down-load that software and my email to Ford have gone unanswered.
Can't I use a "multimeter" to test the ABS at each wheel and at the pump, to locate the problem?
