Code p0453 refers to evaporative emission (EVAP) pressure sensor-- high out put === causes wiring short to positive--- EVAP pressure sensor--- ECM
I would change the sensor unless you have been messing with the wires.

2009 chevy traverse engine light flashs only over 25mph


A flashing check engine light means that you have an engine misfire, You need to have the fault codes read with a code reader or scan tool. Many auto parts stores do this test for free (except Calif.)

What does it mean when code p1516 shows up on a06 chevy impala


There is a service bulletin on this for some Chevy trucks, may include your model of car. I would check with Chevy to be sure.
The code means the computer has received a reading from the throttle position sensor that is out of range and not what it should be.
The throttle actuator control module would need to be tested to proceed.

The power light, seperate from the check engine light, is usually a transmission code. Have the vehicle scanned with a code reader so you can isolate the issue.
