When your Prius has P0606, the PCM may no longer be able to do this job effectively. The PCM’s job is to manage the engine timing and interpret the data for optimal combustion. Misfiring- When driving the vehicle may misfire as though it has normal ignition problems.Service Engine Soon Light- This is the most common symptom associated with P0606 in your Prius.It’s highly unlikely that the check engine light will be the only symptom.

Here are the most common symptoms of P0606 in your Prius. When it fails this test P0606 will be stored in it’s memory and you’ll get the P0606 trouble code. The PCM regularly performs a self diagnosis cycle. If your Prius has P0606 it’s highly likely that the ECM/PCM (engine or powertrain control module, they mean the same thing) has failed. Which means that it has the same meaning for the Toyota Prius that it would for any other vehicle.
