p0180: this stands for the fuel temp sensor, but i have no idea what it means...

p1165: no idea at all
p0464: no idea at all...

anyone know what they mean???
thanks

 

According to actron.com the P0464 means:
Fuel Level Sensor CKT Intermittent
Doesn't mean much to me

 

P0180 = Fuel Tank Temp Sensor
P1165 = Swirl Control Valve (Cali Spec only)
P0464 = Fuel Level Sensor Circuit

The P0180 and P0464 indicate something wrong with the sensors in the fuel tank itself. Either the sensors themselves are bad, or the readings they are putting out do not make sense in relation to the engine coolant temp and/or the intake air temp (as measured by that sensor). Have you been messing around with your fuel pump assembly?

The P1165 seems to be simpler... check the vacuum line connecting up to the swirl control valve (cylindrical plastic piece near driver side strut tower) and all other vacuum lines. If your lines are not hooked up correctly, your swirl control valve will not operate correctly and the butterfly valves in the intake manifold will not open up. Your car will be really slow past 3k rpm so you will know right away if that is the problem...
