OBD-II Diagnostic Trouble Code
C0710 — Steering Position Signal
C0710 indicates a problem with the steering position signal received by the brake or stability module. The signal was missing, invalid or not plausible compared to yaw rate and wheel speed data. Meaning can differ by OEM; it may refer to a hardwired sensor or a network message.

What this means for truckers
C0710 (Steering Position Signal) — steering angle sensor signal fault.
Before you replace parts — try this first
C0710 on the Brakes system is most often steering angle sensor not calibrated — not a dead part. On commercial diesels especially, work these in order before spending money on parts:
- Confirm the symptoms. Match what your truck is doing to the Symptoms section below. If the code is set but the symptoms are not there, clear the code and re-test after a drive cycle — it may not return.
- Clean and dry the sensor connector. Water, road salt, or oil seeping into a connector is the #1 fake sensor failure. Disconnect, look for green corrosion or moisture, spray with electrical contact cleaner, dry, reseat. Many faults clear here for $0.
- Inspect the wiring harness. Trace the wire from the sensor toward the ECM — look for chafing against the engine block, melted insulation near the turbo or exhaust, or pinch points where a clamp has rubbed through.
- Test the sensor before swapping it. Most Common Causes (below) list the expected voltage or resistance range — a $20 multimeter saves a $300 sensor swap that does not fix the problem.
- Only then, replace the part. Use the OEM or a tier-1 aftermarket. Cheap sensors throw the same code in two weeks.
Symptoms
Stability control light on and stability control disabled. ABS normally works. Often appears after alignment, steering repair or battery disconnect.
Common causes
- CommonSteering angle sensor not calibrated ($80–$200)
- OccasionalWiring or network fault from the sensor ($100–$400)
- OccasionalFailed steering angle sensor ($250–$800)
- OccasionalWheel alignment off so steering wheel is not centered when driving straight ($150–$350)
How to fix
Calibrate the steering angle sensor
When to use: After alignment or steering work
Check steering angle data while turning
When to use: To find dropouts or wrong direction
Check alignment and steering wheel centering
When to use: Steering wheel is off center
Repair wiring or replace sensor
When to use: Signal is lost or erratic

Frequently Asked Questions
Can I drive with code C0710?
C0710 is severity 3 — plan service within a few days. Performance is likely degraded already (you may feel reduced power, harsher shifts, or slightly worse fuel economy). Continuing to drive risks additional damage to adjacent components.
How much does it cost to fix C0710 on a commercial truck?
Total repair cost ranges $80–$800 depending on the root cause. The cheapest fix is usually the first one listed below — Steering angle sensor not calibrated — which is also the most common. On commercial trucks the cost is usually higher than passenger vehicles due to part availability and shop labor rates ($120–185/hour at most truck shops, vs $90–130 at general auto shops). DIY-capable fixes (sensors, hoses, filters) are at the low end; major component replacements (turbo actuator, high-pressure fuel pump, transmission solenoid pack) are at the high end. Always diagnose with a scan tool BEFORE replacing parts — guessing wrong on a $1,500 turbo actuator when the actual issue was a $30 boost hose is a common expensive mistake.
Will C0710 fail a DOT inspection?
C0710 is generally not a direct DOT inspection fail item by itself. Inspectors focus on safety-critical systems (brakes, steering, tires, lights, hours-of-service). However, the check engine light alone can trigger additional inspection scrutiny. Best practice: fix the code and clear it before a planned inspection.
What's the difference between C0710 and related codes?
There are no directly related codes in the standard catalog. Diagnose this code on its own merits and check for any companion codes the ECM may have stored alongside it.
How do I prevent C0710 from coming back after a repair?
For C0710 (Steering Position Signal), prevention centers on the brakes system. Clean wheel speed sensors at every brake service. Inspect tone rings for cracks or rust. Keep ABS sensor harnesses away from chafe points. Don't drive through deep water that can flood the rear wheel-speed sensor connectors.
