Yes the tank must be dropped, but not entirely removed, the sensor is on the top of the tank.

the evaporative emission system (EVAP) control system pressure sensor has sent high voltage to the ecm or engine control module and triggered this code either the purge valve located under the car by the gas tank has gone bad, or the charcoal canister has become gas soaked and is pressurizing from gas fumes, or the sensor or wires have shorted , there is also a secondary valve located und the cover of the intake that should also be checked for shorts that can trigger this code but usually it is the one under the car that goes out 9 out of 10 times it is from fuel being burped into the evap canister or charcoal canister from the gas tank which is caused from overfilling the tank or mid day heat of 90 or better with a full tank

They didn't have a fuel pressure sensor in 2000.... are you referring to the fuel tank pressure sensor? That sensor measures the vacuum/pressure in the fuel tank and is related to evaporative emission control. That sensor is externally located directly on top of the fuel pump on top of the fuel tank. It has a 3-wire connector plugged into it.

Make sure you tighten your gas cap when refueling, until it clicks a minimum of 3 - 5 times. If this does not turn off the light, have it cleared at an auto center, & replace the defective fuel cap. They use an intricate system to equalize air pressure in the tank, to allow gas flow, wthout allowing evaporation of the gas. (Green Friendly) & EPA rules. Thew system is pressurized, If cap defective,, it will set the code.

Possible causes:------Faulty fuel tank pressure sensor.

• open/short in wiring harness between pressure sensor & VCM.
• Faulty VCM.

---------------- The fuel pressure sensor has to be checked and replace.-----------Thanks.Helpmech.

The Fuel tank pressure sensor or Fuel pressure sensor? The pressure sensor for the fuel line is located in the Engine compartment, although I don't have the exact location it is located on the fuel line. If your talking about the Fuel level sensor that is actually part of the Fuel pump assembly. You should pick up the Haynes Repair manual on your vehicle before attempting either repair.

EVAP Emission Control System - Small Leak Detected (1.0 mm). This code can be set when 1. fuel filler cap is not completely tight, 2. when various hoses get punctured or the canister close valve does not seal completely, 3. there is an actual leak in the charcoal canister, fuel tank, or other EVAP system component, 4. if any one of these components are malfunction (a), fuel tank pressure sensor, (b) purge control solenoid valve, (c) canister close valve, or (d) fuel cap. An engine vacuum leak would not set this code, Usaly there is a sensor on fuel tank called Evap controll switch that has failed
