Check engine light only at half tank

Post by Earn_est_89 »

I have a s80 2006 2.5t AWD. My car check engine light comes on at half tank and throws the code p0089. I've replace the fuel pressure sensor and fuel pump and module. I have even bought a new gas cap. everytime i fill up the tank the light goes away on its own but when it gets to half tank it comes back .If I let the gas gets too low it stalls and becomes hesitant. I'm stuck has anyone expirenced this ?????

I think I'm experiencing this same thing with my 2006 XC70. Did you figure out a solution?
