C0034 on Ford
Right Front Wheel Speed Sensor Circuit
C0034 on Ford vehicles indicates right front wheel speed sensor circuit. Au7o has documented this code across 1 Ford model — most commonly on Transit Connect. C0034 is a chassis/brake code indicating a fault in the right front wheel speed sensor circuit. The ABS module uses this sensor to monitor right-front wheel rotation for anti-lock braking, traction, and stability control, and it sets the code on an open, short, or invalid signal. Expect the ABS, traction, and stability control warning lights to come on with those features disabled, though standard braking generally remains available. Typical repair costs on Ford range from $120 to $650, depending on the specific model and root cause.
Common Causes of C0034
- •Failed right front wheel speed sensor
- •Damaged or chafed sensor wiring
- •Corroded or loose sensor connector
- •Damaged or contaminated tone/reluctor ring
- •Excessive air gap or wheel bearing looseness
- •ABS control module fault

Transit Connect owners report intermittent ABS and traction control warnings caused by wheel speed sensor signal dropouts, often due to sensor contamination, corrosion at connectors, or damaged wiring near the hubs. The issue can be intermittent and may also disable stability control functions until repaired. This pattern appears in NHTSA complaints and owner reports describing ABS/AdvanceTrac warnings and sensor replacement.
