Last friday, I started my car and then it dies like 3 seconds after. Ended up taking it to the dealership, and they just told me today, that the intake is causing problems because it is sucking in too much air.
Does the vehicle sucking in too much air actually cause this problem? I brought my car to a Toyota dealership initially, and it pulled fault code P0657.
What does this mean?
OBD Code P0657refers to
The ECM continuously monitors its internal memory status, internal circuits, and output signals to the throttle actuator. This self−check insures that the ECM is functioning properly. If any malfunction is detected, the ECM will set the code and illuminate the engine light.
Symptoms
Possible sumptoms of OBD code P0657
- Engine Light ON (or Service Engine Soon Warning Light) - Engine may not start
Causes
Possible causes of OBD code P0657
- ECM Harness power supply circuit is open or shorted - ECM Programing - Faulty ECM The Error code is generally activated on detection of the following conditions: Indicates the ECM has experienced an internal memory fault.
Possible Solutions
- Resecure ECM connectors - Reprogram ECM - Replaced ECM
I thought the problem may have been either my high pressure fuel pump or some kind of fuse. Does this seem right? Or are they trying to screw me out of my extended warranty coverage?
