P0606
CIRCUIT DESCRIPTIONThe ECM performs internal tests on the microprocessor and some specific data coming into the processor.
CONDITIONS FOR RUNNING THE DTC
The engine speed must be more than 1,120 RPM.
CONDITIONS FOR SETTING THE DTC
The ECM determines that an internal data test did not pass.
ACTION TAKEN WHEN THE DTC SETS
The ECM illuminates the Malfunction Indicator Lamp (MIL) and records the operating conditions in the Freeze Frame on the first drive trip that the diagnostic runs and fails.
CONDITIONS FOR CLEARING THE MIL/DTC
The ECM turns OFF the MIL after 3 consecutive drive trips that the diagnostic runs and passes. A History DTC clears after forty consecutive warm-up cycles in which no failures are reported by this or any other emission related diagnostic. The scan tool clears the MIL/DTC.

2. Diagnose any other stored DTCs prior to diagnosing the P0606. DTCs for the throttle position sensor and other sensors may cause the ECM to set a P0606.
