I do have HARD STARTING with the car but after carrying out scan test the report goes thus:
Code P1496 5volts supply too low
code P1599 A/C pressure sensor volts too low
code P0122 Throttle position sensor voltage low
code P0106 Barometric pressure out of range
code P0108 MAP sensor voltage too low
code P0121 TPS voltage does not agree with MAP
code P0113 Intake air temperature sensor voltage high.
carrying out this scanning really proof to me why the checkengine light is always ON, pls, how can I regulate the codes back to normal voltage that it`s suppose to operate?
the car scanner I used was X - 431 Launch.
Check your battery first, if it'snot up to stuff it will send false codes. Make sure all your vacuum lines are connected an dno vacum leakage. You could have a few sensors there tthat require more indepth testing. It sbetter to have a pro look at this to actually save you money so you don't by unecessary parts.

Thanks hmac300, the check engine light came up after I replaced the engine with a used one, but with it I still cruise the car but the fuel consumption is high and I do experience hard starting, but I use to step on the throttle pedal and after like 5 to 6mins it come bac to notmal.

I think the is in order now but still consume more fuel than before and when I touched the exhaust pipe I use to notice black smoke deposited on it.
