hello
ive just fixed my code 91(Fuel Tank Pressure Sensor low input) using the potentiometer fix in this thread https://honda-tech.com/zerothread?id=767817
but after driving for two days..code 90(Evaporative Emission Control System leak detected in the fuel tank area) popped up..what can i do to fix this problem?..where can fuel be leaking?
can it be the fuel rail?'cause i installed an aftermarket one awhile back.
i would appreciate any help..thanks!

The fact of the matter is this: Providing a static voltage input to the ECU for the FTP sensor implies that this voltage does not change. Well at one point, the ECU runs an EVAP monitor test to check for pin holes in the EVAP plumbing. It does this by closing down a solenoid which lets pressure build inside the gas tank. This pressure increase should be seen from the FTP sensor.

When you got this code, were you just about on empty [gas tank]? If yes, reset the ECU, fill up and try to keep the gas level in the 1/2 - 3/4 marks. I'm not saying this works, but from I've seen an empty tank triggers this code.
