P060BInternal Control Module A/D Processing Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- The analog-to-digital converter turns every analog sensor voltage into a number, so a faulty converter can falsify many values at once. The module checks it by timing its start-up calibration (GM 6.6 L diesel: 0.30 s or longer is a fault), by converting fixed internal reference voltages (about 4.73–4.83 V must be read), by grounding a test channel that must then read near 0 V (Ford diesel: over 249 mV is a fault) and by comparing with a second converter. GM sets it in the first trip, Ford with the check engine and wrench lamps as a level 3 check; the module usually enters limp mode. Ford fixed an F-150 2.7 L case (with misfire codes) by reprogramming. GM also uses P060B in the brake module – then ABS warnings appear and the engine module is not the culprit. The old wording 'A and D' simply spelled out 'A/D'.
- What you may notice
- Check engine light, at Ford also the wrench lamp
- Reduced power or limp mode
- Several sensor or misfire codes at the same time
- ABS/ESC warning if the brake module set the code
- Likely causes
- LikelyFaulty module software (update available)
- PossibleUnstable supply voltage or poor ground at the module (weak battery, voltage spikes)
- PossibleInternal defect of the converter or its chip
- RareShorted sensor input pulling the converter reference
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
