P06D1 Internal Control Module Ignition Coil Control Performance

Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modeNo

On ignition systems where the coils are driven through a separate driver chip inside the engine module, P06D1 reports that this internal coil control does not work correctly. Ford checks the communication with the coil driver chip continuously and sets the code within 1 s at 200–3200 rpm, positive torque and 11–16 V. GM Europe's V6 (Saab 9-5 2.8 T) reports it as an internal engine module fault with the lamp after two trips. Misfires or rough running can follow if coils are no longer fired correctly. Primary circuit faults of individual coils are P0351–P0360, driver shorts P2300 ff. Check supply and ground, look for software updates; otherwise the module is the likely cause.

Likely causes

Coil driver chip or internal communication in the engine module faulty
Engine module software
Supply or ground problem at the module
Shorted coil overloading the driver

Symptoms

  • Check engine light
  • Misfires or rough running
  • Possibly no start
