    P0452 DTC not clearing

    Hello,

    I flashed the PCM three times now and for some reason, I still get a DTC for

    P0452 Fuel Tank Pressure Sensor Circuit Low Voltage, even though I unchecked it from the DTC list. the scanner picks it right up, right away, even when I reset the DTC list in the PCM.

    Is there something else that I need to do in conjunction with turning that DTC off?

    My application is a V8 RX-7, so I am not sensing the fuel tank pressure. Your help is greatly appreciated! Zach

    Nevermind. I forgot to set the error mode to 3.
