P060A - Internal Control Module Monitoring Processor Performance
System
Powertrain (Engine & Gearbox)
Technical Description
The control module has detected a fault in the Internal Control Module Monitoring Processor Performance (P060A). The underlying code points specifically at the main processor and its watchdog circuit.
Multimeter Test Points & Nominal Values
| Test Point / Component | Measurement | Nominal Target Range | Test Condition |
|---|---|---|---|
| Internal Control Module Monitoring Processor Performance – Permanent B+ Supply | Voltage (V) | 12.4 - 12.7 V (ignition OFF) / 13.5 - 14.7 V (engine running) | At module supply pins |
| Internal Control Module Monitoring Processor Performance – Ignition-Switched Supply | Voltage (V) | 11.8 - 14.4 V | Ignition ON |
| Internal Control Module Monitoring Processor Performance – Ground Connections Voltage Drop | Voltage (V) | < 0.1 V per ground point | Under load to battery negative |
| Internal Control Module Monitoring Processor Performance – 5 V Reference Outputs | Voltage (V) | 4.95 - 5.05 V per circuit | Ignition ON, sensors unplugged one at a time |

Ignition ON
Under load to battery negative
Ignition ON, sensors unplugged one at a time
Oscilloscope Waveform Analysis
500 ms/div, 5 V/divPossible Causes
Internal processor or watchdog reset, often from voltage spikes, heat, or cold solder joints inside the module
Internal Control Module Monitoring Processor Performance is electrically operational but performing outside calibrated tolerance
Chafed or pinched wiring harness along the signal path to Internal Control Module Monitoring Processor Performance
Poor ground connection or excessive voltage drop (> 0.1 V) at the ground point for Internal Control Module Monitoring Processor Performance
Defective internal output driver or reference circuit in the control module for Internal Control Module Monitoring Processor Performance
Symptoms
Recommended Solution
Check supply quality and ground, look for water ingress at the module connector, and heat/cool the module while logging — if the reset returns the board is at fault.
Verify underlying mechanical operation and rule out blockage, vacuum leaks, or mechanical binding.
Verify loaded supply voltage and harness terminal pins at Internal Control Module Monitoring Processor Performance.
Check circuit continuity and ground-side voltage drop (< 0.05 V) for Internal Control Module Monitoring Processor Performance.
Inspect module enclosure and connector headers for water ingress, fretting corrosion, or PCB thermal damage.
Mechanic's Tip
A resetting processor often sets a swarm of consequential codes — clear all, road test, and see which code returns FIRST.
