2003 kia Sedona at a cold start the rpm runs very high and it will take over 2 minutes before its slowly starts to drop.


TPS, IAC, EGR, MAF, MAP. all sensors all having to do with the way the car starts and runs. Does it idle fine after warm up or does the idle jump up and down, or does it go so low sometimes, you think it's going to die on you? I'd look at the TPS and IAC 1st. Go to autozone or advanced auto parts and have then plug the OBD II code reader into your ECU and see if they can pull a code.

Go to www.hmaservice.com and register your vehicle by VIN #..
you'll then have access to wiring diagrams, shop manuals,
service bulletins, illustrations, etc. To diagnose a 2000 or 2001 1.5L Accent Diagnostic Trouble Code (DTC) P1128 (FUEL SYSTEM LEAN -- PART LOAD), check the following:
  • Check the intake system for air leaks.
  • Check that the Mass Air Flow (MAF) Sensor (P/N 28164-22610) operation meets the specifications listed below. If the MAF sensor output is significantly lower than the reference value (10% or more), then replace the MAF sensor.

P1506 code on my 1999 ford ranger


Here is a link to a page of codes for Ford. I say that but with the OBD-II you should have in your model the codes should be the same for all makes and models Per Uncle Sam.

http://www.obd-codes.com/trouble_codes/ford/

your specific code indicates an Idle Air Control Over Speed Error this doesnt mean that there is a problem with the sensor although there cold be a problem with it. It means something made the sensor not work correctly. Dont go replacing parts at random. I did this with my 89 f150 and spent hundreds in parts for a plugged injector. Go figure.

Hope this helps... Dale

Does the check engine light automatically come on at 180000 for a 2004 Ford Ranger?


No it's not programmed to come on at any specific mileage. If it does come on then there is a problem detected by the computer. You will need an OBD II code reader to retireve the code(s). Once the code(s) have been retrieved, you can figure out how to fix it.

P0100 OBD-II Trouble Code

Technical Description

Mass Air Flow (MAF) Circuit Malfunction

Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.

You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.
Causes

A code P0100 may mean one or more of the following:

* The MAF may be disconnected, or a wiring connection may be bad.
* The MAF sensor may be faulty.

Possible Solutions

Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
Then start with the cheapest, easiest repair procedures:

* Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
* Replace the MAF sensor.
