1. Back probe into the Dark Green wire at the Fuel Tank Pressure (FTP) sensor and monitor voltage.
2. Check for voltage to drop to 0 when moving the wire harness Next to the tank.
Trouble code P0452 means: Evaporative Emission System Pressure Sensor/Switch Low Input
Trouble code P0452 means: Evaporative Emission System Pressure Sensor/Switch Low Input

P0452 - Fuel Tank Pressure Sensor Circuit Low Voltage
The code P0452 on a Buick LeSabre is a fuel tank pressure sensor circuit low voltage warning. This sensor is on the top of the fuel tank.
P0452 is fuel tank pressure sensor circuit fault. I have never heard of a P0440, but 400 series codes are in the emmissions, i.e., EGR and Evap system. I would try to fix the 452 and see if the 440 goes away with it.
P0455 and P0452 have to do with fuel vapor leaks, will not cause a starting problem. P0340 is a cam sensor code. You need to diagnose for a failed cam sensor.
Fuel tank pressure-check your gas cap etc.
P0452 Evaporative Emission System Pressure Sensor/Switch Low Input I just fixed this the other day. First of all make sure your fuel cap is on tight as this may be the cause. If the service engine soon light is still on then do the following: 1) Your Fuel Tank Pressure Sensor might be bad or it might have broken like it broke on mine. Or.... 2) If it is broken you have to buy a new fuel pump because the Sensor is not sold as a separate part on your vehicle.
i have a izuso rodeo 1999 3.5 liter i need how i fix the code po452 were is the location is the sensor and how is the sensor
