Does anyone knows how to fix the code P0452 on the 04 Acura MDX?|||The FTP (fuel tank pressure) sensor is located near the fuel tank. It is mounted on a bracket and has an electrical connector and two hoses connected to it. To troubleshoot the code you need a scan tool to view the computer data while you test the sensor in several different conditions. Lacking a scan tool and the knowledge to perform the troubleshooting, the only thing you can do is locate the sensor, inspect the electrical connection and the hoses for problems and then replace the sensor if they are ok%26gt;|||Fuel Tank Pressure Sensor (FTP)
P0452 Evaporative Emission Control System Pressure Sensor Low Input
Probably located in the fuel tank, on the pump assembly. I'm just guessing though.
Normal value is usually somewhere near 2.5 Volts at atmospheric pressure (may fluctuate some due to altitude). It shouldn't ever be above 4.5 Volts.|||It's located on the top of the fuel tank. Are you sure it's the sensor? Did you check or replace the gas cap? If the gas cap doesn't seal correctly it can cause that code too.
