P060B — Control Module Analog-to-Digital Processing Performance Fault

Severity: medium Drive with care, to a shop

What P060B means

Inside the engine control module, an analog-to-digital converter turns sensor voltages into digital values the processor can use. P060B is set when the module's self-test finds that this conversion is not performing correctly. Sensor readings may then be wrong even if the sensors themselves are fine.

Symptoms

  • Check Engine light on
  • Erratic or illogical sensor readings
  • Several sensor codes set at once
  • Rough running or hesitation
  • Limp mode or reduced power
  • Symptoms vary with the affected internal function

Possible causes

  1. Low or unstable supply voltage to the module (weak battery, poor terminals)
  2. Poor module ground or corroded connector pins
  3. Voltage spikes or a failing alternator
  4. Fault in the sensor reference voltage circuit (short in the harness)
  5. Software or coding fault, often after programming
  6. Internal hardware failure of the control module
  7. Rarely, interference from damaged wiring

How to diagnose

  1. Scan all modules, save freeze frame data and note which codes appear with P060B
  2. Test the battery: resting voltage and terminal condition
  3. Measure charging voltage with the engine running; it should be steady
  4. Check fuses and relays that feed the module
  5. Inspect engine and module grounds, and the module connector for corrosion or moisture
  6. Check the sensor reference voltage (typically 5 V) and wiring for shorts
  7. Check the software version and look for updates or manufacturer bulletins
  8. Clear the code and see if it returns

Common fixes

  • Charge or replace the battery and clean and tighten terminals
  • Repair power or ground faults, harness damage or connectors
  • Replace a faulty alternator or voltage regulator
  • Update or reflash the module software
  • Repair or replace the control module only after power and ground checks pass

P060B on different brands

Ford · manuals
On Ford, P060B:00 describes an internal control module A/D processing performance condition in the 2024-2025 gasoline OBD monitor strategy; it identifies the detected monitor condition rather than a confirmed failed component.

Questions and answers

What does P060B mean?

The control module detected a problem converting analog sensor signals into digital data. It is an internal self-check, so the cause can be the module itself or its power supply.

Do I need to replace the ECM for P060B?

Not right away. First check the battery, charging system, fuses, grounds, connectors and software updates. Replace the module only if those checks find nothing.

Can I drive with P060B?

Briefly and carefully if the engine runs smoothly. If it stumbles, enters limp mode or sets multiple codes, have it checked before driving more.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
