2009 Chevrolet Malibu LTZ with engine code P0452 after replacing the fuel pump

Question

I recently replaced my fuel pump, and the car still won't start. There was a code that popped up and it read P0452...what can I do to get my car up and running again?

Answer 1

HI there,

This code is for the evap system pressure sensor. This is mounted to the top of the gas tank. This should not prevent the car from starting. You have to determine if the car is lacking fuel or spark. Also, check the security system. If the security light is on the car may be immobilized, this would seem like a fuel pump problem.

Answer 2

P0452 Chevrolet Code - Fuel Tank Pressure Sensor Circuit Low Voltage
