P060B Internal Control Module A/D Processing Performance

P060B is a generic OBD2 powertrain code. It means “Internal Control Module A/D Processing Performance” — the same on every make and model, because the definition comes from the SAE J2012 standard rather than from the carmaker.

The rule of thumb for this area (computer & output circuits): If the car runs normally, get it checked soon. A reference-voltage or processor code can come with stalling or limp mode — don’t rely on the car for long trips until it’s fixed.

“Range/performance” means the signal is electrically valid but doesn’t make sense against what the module expects from the other sensors. That points to a sensor that is dirty, slow or out of calibration — or to a real mechanical problem it is faithfully reporting — more than to the wiring. Typical causes in this area: Low or unstable supply voltage and poor grounds; A shorted sensor pulling down a shared reference voltage; Software that needs an update; Water damage or a failed module.

Fix the cause first, then clear it with any OBD2 scanner or app. Once the fault is gone the car also clears it on its own: the check engine lamp goes off after the self-test passes on three drive cycles in a row, and the stored code ages out after about 40 warm-ups. Clearing without a repair only hides it for a while — and resets the readiness monitors an emissions inspection looks at.

Yes. P060B is a generic SAE J2012 code, so its definition is identical on every make and model. What differs is the cause behind it and the repair procedure, which depend on the engine — that’s why the assistant on this page asks for your car.
