Check evaporator coil sensor location. Thermal regulated chamber allows an accurate setting of temperature. That may include but is not limited to vehicles from Ford, Chevrolet, Dodge, Ram, etc. When the PCM receives a signal from the FTP that there is excessive tank pressure or vacuum the PCM will then send a signal to the EVAP purge solenoid to correct the fuel tank pressure level. In this test program the control temperature sensor was placed on the reservoir, evaporator, and thermal mass (simulating the heat source) to maintain the respective component at a constant temperature. The sensor is located near the evaporating coil. Dip the sensor in ice water, and measure the resistance between its terminals. The shop manual for my car told me to clear the fault codes (after I performed the repair) and do the Onboard Diagnostic tests so that's what I did. WDS should give an indication that the test is active (it may take up to 30 minutes before the test will initialize).
