What P0C62 means
P0C62 means the reference level on the S2/S4 winding circuit of the motor B resolver climbs above its upper limit. GM triggers it at 4.5 V on the 2011 and 2016 Volt and ELR, 4.9 V on the 2019 Volt and 3.0 V on the 2012 two-mode trucks; on the 2016 Volt the level must stay high for 0.2125 s within 0.3125 s, rated Type B over two trips. P0C62 shows up in every GM note of the PIC5856 series, from the 2013 original to version F of 2019, for 2011-13 Volt and 2014-16 ELR, usually paired with P0C58 and sometimes P0C57. Because both windings of the same resolver report high at once, GM's remedy after clean wiring checks is a new motor B position sensor plus the latest module calibration.
P0C62 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0C62
- Service engine soon lamp, often with P0C58
- Reduced propulsion power
- Code may return after clearing until the sensor is replaced
Common causes of P0C62
- Most likelyFaulty motor B position sensor on 2011-13 Volt and 2014-16 ELR (GM PIC5856)
- PossibleOpen S2 or S4 wire or terminal backed out of the connector
- Less likelyDrive motor generator control module without the latest calibration
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C62 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| C | Area: hybrid propulsion. |
| 62 | The exact fault in that area. |
What to do next
- Note P0C62 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 P0C62
What does P0C62 mean?
P0C62 means "Drive Motor B Position Sensor Circuit B High". P0C62 means the reference level on the S2/S4 winding circuit of the motor B resolver climbs above its upper limit. It is a generic code, so it means the same on every make.
Is it safe to drive with P0C62?
Drive gently and only to a workshop. With P0C62 the car can go into limp mode (reduced power) to protect itself.
Will P0C62 fail an emissions test?
Yes, it can. P0C62 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0C62 to fix?
Difficulty: workshop only. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P0C62 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
