What Does P1728 Mean?
The powertrain control module has detected inconsistent wheel speed signals between multiple wheel speed sensors. This indicates one or more sensors are providing readings that don't correlate with the others during normal driving conditions.
Common Causes
40%
Faulty wheel speed sensor or damaged sensor wiring
25%
Damaged or contaminated tone ring (reluctor ring) on hub assembly
20%
Mismatched tire sizes or significantly different tire wear
10%
Corroded or loose wheel speed sensor connector
5%
ABS/PCM module programming issue or fault
Diagnostic Steps
1
Step 1: Verify all tires are same size and have similar tread depth/wear patterns
2
Step 2: Use scan tool to monitor live data for all wheel speed sensors during test drive
3
Step 3: Inspect each wheel speed sensor for physical damage, air gap, and connector condition
4
Step 4: Check tone rings for damage, missing teeth, or metallic debris buildup
5
Step 5: Test resistance and AC voltage output of suspect wheel speed sensor(s)
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The powertrain control module has detected inconsistent wheel speed signals between multiple wheel speed sensors. This indicates one or more sensors are providing readings that don't correlate with the others during normal driving conditions.
The most common cause of P1728 (Different Wheel Speed Signals Range/Performance) is: Faulty wheel speed sensor or damaged sensor wiring
Typical repair costs for P1728 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May disable ABS, traction control, and electronic stability control. Can cause transmission shift issues. Drive with caution and reduced speed, especially in wet conditions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1728 to identify the root cause.
