How do I clear check engine light

The check engine light is set by the onboard computer detecting a malfunction or out of tolerance condition. The code(s) can be read with an OBD-II scanner. Once the condition(s) that cause the codes are repaired, the code can be cleared with the OBD-II scantool. You can purchase these tools at local auto parts stores. Be careful though; the cheapest ones will only read the codes, but cannot reset the Check Engine Light.

How to read check engine light "95 F 450 heavy duty truck

Should be OBD 1 which does not need a scanner. You jumper two wires at the plug in the engine compartment to make the light flash.
If you do an internet search for Ford KOEO test you should find photos and instructions including what the codes mean.

My check engine and ESC lights are on in my 2007 Kia Sedona LX. Code P054 - likely cause? Does it have to be a dealer fix? Car's performance doesn't appear to be affected, handles great thusfar,...

Well, I would like to help you but P054 is not a valid code. There are not enough digits for it to be a valid OBD code. I would recommend reading the code again and make sure you post it correctly if you want help with it.

As for the Check Engine light and the Electronic Speed Control (ESC) light being on, this means that there is a malfunction in one of the many systems that are monitored by your Powertrain Control Module (PCM). The PCM has also disabled your ESC (A.K.A. cruise control) for whatever reason.

It should be noted that although the problem does not seem to be affecting the way the vehicle drives, it is very likely that whatever is wrong is going to destroy some high-dollar parts like the catalytic converters if you don't get it fixed.

As far as getting it fixed at the dealer...It all depends on EXACTLY what is wrong. Most OBD fault codes can be serviced by anyone with the correct information for the code involved, providing they have the equipment and knowledge to properly diagnose the code. Codes that involve reprogramming of the PCM to fix are usually better to have done by the dealer. In these cases, the reprogramming can be done under emmissions warranties for free if the vehiclle meets certain criteria.

Engine light on

This is OBD - On - Board -Diagnostic Display.
On Board Diagnostics, OBD-II, is required on all automobiles and light trucks from 1996 onward. OBD-II is a set of specifications for monitoring and reporting on engine performance in modern automobiles.
If the Service Engine light is on, then connecting a Code Scanner on OBD Connector, the Code is picked up and the code explanation can be found. If this is a False Code, this can be Cleared with the code scanner, after reading the code. The location of OBD-II connector in your car can be found here:
Remember the Check Engine light only comes on for emissions-related failure (which includes fuel and ignition, too). A separate warning light will illuminate if there are non-emission problems such as low oil pressure, charging system problems, etc.
If the light is on because of a misfire or fuel delivery problem, and if the problem does not occur after three drive cycles, the Check Engine light may go out. Whether the light goes out or remains on, a code will be snt and remain in the computer memory to help you diagnose the fault.
More information for the codes can be found here:
After the code is picked up with a scanner, the code explanation is founded, and a decision has to be made to fix the problem or to clear the code. This can be done with the same scanner. If you do not have a scanner, any car repair shop can do the job.
