Service engine light is on, code P0452 what could be the problem?
You have either a bad fuel tank pressure sensor or the wiring near the sensor is damaged / broken wire - rodent chewed through it. These are the most common causes of this code. Changing this sensor requires the removal of the pickup box from the chassis.
