C061A code meaning
Brake Pedal Position Sensor B Offset Exceeded Learning Limit
What C061A means
C061A is the same learn-limit check for the second channel, B. Many pedal sensors hold two independent elements; on GM trucks since 2012 one potentiometer feeds the ECM and the other the BCM, each with its own 5 V reference, ground and signal. Each controller keeps its own released-position value and updates it whenever it sees a lower voltage, so a short dropout on one channel can leave B with a skewed zero while A stays correct. The Hitachi patent rejects a learned zero outside its prescribed range as a sensor fault. Snap-on and GM's 16-NA-155 stress relearning in both modules without touching the pedal. Which physical channel a maker calls B is not public, and no maker documents C061A; channel A is C0619.
C061A at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of C061A
- Brake system warning or message
- Mismatch between modules about pedal state, e.g. brake lights versus cruise control
- Shift interlock or start function may act up
Common causes of C061A
- Most likelyDropout or fretting corrosion on the channel B reference, ground or signal pin
- PossibleLearn done in only one module, or the pedal moved during the learn
- PossiblePedal rest position changed by a mat, bracket damage or adjustment
- Less likelyDrifting second element inside the pedal sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of C061A means
| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 1A | The exact fault in that area. |
What to do next
- Note C061A 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 C061A
What does C061A mean?
C061A means "Brake Pedal Position Sensor B Offset Exceeded Learning Limit". C061A is the same learn-limit check for the second channel, B. It is a generic code, so it means the same on every make.
Is it safe to drive with C061A?
C061A does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will C061A fail an emissions test?
C061A 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 C061A to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. This is a job for a workshop.
Will C061A clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
