Code P0606 2007 Toyota Prius Description
The ECM memory status is diagnosed by internal mirroring of the main CPU and the sub CPU to detect Random Access Memory (RAM) errors. The two CPUs also perform continuous mutual monitoring. The ECM illuminates the MIL and sets a DTC if: 1) outputs from the two CPUs are different or deviate from the standards, 2) the signals sent to the throttle actuator deviate from the standards, 3) a malfunction is found in the throttle actuator supply voltage, and 4) any other ECM malfunction is found.
What are the Possible Causes of the DTC P0606 2007 Toyota Prius?
- Faulty Engine Control Module (ECM)
- Engine Control Module (ECM) Harness power supply circuit is open or shorted
- Engine Control Module (ECM) Programming
How to Fix the DTC P0606 2007 Toyota Prius?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
