What P2B60 means
P2B60 checks whether the valve actually goes where it is told. On GM's 3.0 L Duramax the code sets when the gap between desired and measured position exceeds 12 % in 160 of 200 samples, only with a steady command, closed-loop control active and no coolant or outside temperature sensor fault (Type B). For LM2 trucks and SUVs GM issued 20-NA-039 and 22-NA-082 (ECM software), PIP5764 (corroded terminals at the centre actuator connector) and PIP5791, which has the valve swept from 25 to 95 % with GDS2 and then relearned. Hyundai and Kia link P2B60 to the cleaning routine of the ITM module on 1.6 T-GDI engines (23-EE-002H, 24-FL-003H, Kia ELE 285) and fix it with software.
P2B60 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 10 hours
- Clears after repairAfter a drive cycle
Symptoms of P2B60
- MIL on after two drives
- Engine temperature fluctuates or warms up slowly
- Often no driveability complaint beyond the warning lamp
Common causes of P2B60
- Most likelyEngine control software (GM 20-NA-039 / 22-NA-082, Hyundai/Kia ITM logic)
- PossibleCorroded terminals at the valve actuator connector (GM PIP5764)
- PossibleValve sluggish or not learned, needs a relearn after test
- Less likelyValve does not follow commands although wiring is fine
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2B60 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| B | Area: hybrid propulsion. |
| 60 | The exact fault in that area. |
What to do next
- Note P2B60 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 P2B60
What does P2B60 mean?
P2B60 means "Engine Coolant Flow Control Valve Position Sensor Circuit Range/Performance". P2B60 checks whether the valve actually goes where it is told. It is a generic code, so it means the same on every make.
Is it safe to drive with P2B60?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2B60 fail an emissions test?
Yes, it can. P2B60 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 P2B60 to fix?
Difficulty: medium. A typical repair takes 0.5 to 10 hours of work. This is a job for a workshop.
Will P2B60 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.
