Check engine codes.
The wifes 01' 4x4 Blazer with the 4.3l Vortek is giving out 3 codes.
1. P0453
2. P0446
3. P0452
Any help with these would be great.
A bit of recent history. The only work I've had to do is replacement of the fuel pump about a month ago. Other than that it's been fine.

1. P0453 Evaporative Emission Control System Pressure Sensor High Input
2 P0446 Evaporative Emission Control System Vent Control Circuit Malfunction
3. P0452 Evaporative Emission Control System Pressure Sensor Low Input
Sounds like something is up with the evap system.....

RE: Check engine codes.
Reset the codes and make sure your gas cap is tight. See if they come back. The P0453/P0452 seem erroneous.
