Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Tank Pressure Sensor (CNG)
Fuel Tank Pressure (FTP) sensor is integral to gas regulator. FTP sensor provides information on fuel system pressure to compuvalve. When ALT mode is selected using ALT/GAS fuel switch, compuvalve sends an input signal representing CNG pressure level to instrument cluster fuel gauge. FTT sensor and FTP sensor inputs are used to calculate amount of fuel.
