Advanced Diagnostics - DTC P1193: Fuel Tank Pressure (FTP) Sensor Circuit High Voltage











General Description
The fuel tank pressure (FTP) sensor senses fuel tank absolute pressure and converts it into electrical signals. The FTP sensor outputs low signal voltage at low fuel pressure and high signal voltage at high fuel pressure. If the FTP sensor output voltage is a set value or more, the powertrain control module (PCM) detects a malfunction and stores a DTC.
