Hi. I have a 2001 Toyota Echo with over 180,000 miles. I have a check engine light. The code that comes up is: P1656 (Intake CMP Sensor Actuator Solenoid Control Circuit). I'm wondering if I need to change the Cam Shaft Sensor or the Cam Shaft actuator solenoid.
Engine: 1.5 liter
Got code from ECM: P1656
This code is for your oil control valve, you may want to remove it and see if the screen is clear.With all the miles you have there may be some clogging on the screen if so just clean it with some carb cleaner and make sure it is good and clean.This should take care of your problem.Good luck,Don
