C0627 code meaning
Variable Effort Steering Sensor Circuit High
What C0627 means
The high counterpart: the sensor signal sits above the top of the band the module treats as valid. In the Kelsey-Hayes design a healthy channel peaks near 4.4 V on a 5 V supply, so a reading close to the supply rail or beyond it points to a short to the reference or to battery voltage, or to a broken sensor ground that lets the input float high. That patent handles high, low and in-between levels as separate faults so service can tell them apart. Ford's variable-assist systems used such a steering wheel rotation sensor together with road speed, and Ford's effort patent names steering rate and angle as inputs. No maker publishes C0627. As with C0626, the module ignores the sensor and steers on a fixed or speed-only curve.
C0627 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0627
- Variable assist disabled, steering effort fixed
- Steering warning lamp or message
Common causes of C0627
- Most likelySignal wire shorted to the 5 V reference or to battery voltage
- PossibleOpen sensor ground letting the signal float high
- PossibleSensor output stage failed and stuck high
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0627 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0627
What does C0627 mean?
C0627 means "Variable Effort Steering Sensor Circuit High". The high counterpart: the sensor signal sits above the top of the band the module treats as valid. It is a generic code, so it means the same on every make.
Is it safe to drive with C0627?
C0627 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will C0627 fail an emissions test?
C0627 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0627 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will C0627 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
