Treadway:
op, the Ect sensor you changed, i'm guessing it is the one visible at the top close to the engine. That is the wrong one. The car has two, there is one at the bottom of the radiator, get that one replaced and you're home free, your engine will start just fine at cold start and your fuel economy will improve. From a honda civic user who also changed the top one thrice but the code kept returning before i eventually discovered the car had another attached to the radiator base. Cheers

Elxandre:
How did you measure the mpg sir?

GAZZUZZ:
Trace the temp circuit connections from source to ECU.

If it is fine, replace the Engine ecu.

luvinhubby:
Check your power steering oil containers, it's often neglected by car owners & technicians. When dirty, it pushes dirt into the pump causing damage and failure.
More tips coming.

Namzy:
Cold switch or coolant temperature sensor? Check the wiring if you are sure you replaced the sensor with a good one. Also your serpentine belt needs replacement for the battery light and power steering wahala as its loose hence all connected pulley parts temporarily misbehaves especially when wet

Dozieson:
Leave these stories and check your thermostat. It may have failed inside the engine. Except you will continue using the car that way

Dozieson:
P0128 may also mean that your car engine thermostats has either failed or removed. So your mech needs to check if the thermostat is still intact and working well or removed

emy77:
You presently have no engine thermostat in your civic, or at best its stuck in an open position.

Go to oyingbo and buy a functional thermostat, install it, make sure your radiator fans work off and on as per factory setting (and not the always on naija mechanics advocate).

Do these things, and thank me. Surprising folks still do not appreciate the effect of these things on car fuel economy.
