What does EVAP fuel tank pressure sensor do?
What does EVAP fuel tank pressure sensor do?
The fuel tank pressure sensor is responsible for detecting leaks in the fuel system, whether it be an evaporative leak or bad seal on the fuel cap. Once the FTP detects a leak in the fuel tank/system, it alerts the ECU to trigger a “Check Engine” light.
What does p0453 mean on an EVAP sensor?
Basically P0453 means the PCM (Powertrain Control Module) noticed the EVAP Pressure sensor or FTP is indicating a higher than normal pressure (above 4.5 Volts) in the EVAP system. NOTE: On some vehicles the FTP is a part of the fuel pump assembly in the tank.
Why do I get error code p0453 on my fuel tank?
This can happen for several reasons such as a damaged fuel tank pressure sensor, open or shorted signal wire or a damaged sensor connector. The best solutions for this error code entail inspecting the EVAP system and testing the output voltage.
When is the code p0453 set in the ECM?
The code P0453 is set when the ECM reads a high voltage signal from the EVAP control system pressure sensor.
Why does my car have a pending code p0443?
In the absence of an illuminated warning light, code P0443 may be displayed as a pending code. A strong odor of fuel may be present. If the purge valve is stuck open for whatever reason, the idle quality may deteriorate, the engine may run rough at some throttle settings, or the engine may even stall unpredictably.

What is the diagnostic trouble code for evaporative emission control?
P0453 is a diagnostic trouble code (DTC) for “Evaporative Emission Control Pressure Sensor High Input”.
In the absence of an illuminated warning light, code P0443 may be displayed as a pending code. A strong odor of fuel may be present. If the purge valve is stuck open for whatever reason, the idle quality may deteriorate, the engine may run rough at some throttle settings, or the engine may even stall unpredictably.
