P06D1Internal Control Module Ignition Coil Control Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
