Hello

My car is showing me the following codes.

P0442
P0443
P0118
P0123
P1490
P0455

 

did they just appear all at once? was anything done to car before codes appeared? ,p0442 , p0443 , p0455 are fuel system related most likely cause is a loose gas cap, gas cap bad ,bad filler neck. p1490 is low speed fan control relay circuit most likely cause bad relay in the power distribution box(fuse box under hood) you can try switching relays with another one in box ,p0123 throttle position sensor 1 high ,most likely causes bad connection, bad wiring , bad sensor or problem with pcm ,p0118 engine coolant temperature sensor high ,could be thermostat ,bad wiring ,connections , or bad sensor

 

P0123 p0118 and p1490 happend all at once after I replaced the coolant bleeder
