%DETAILS% this answer is out of the haynes code book. code 35 idle air control valve or cicuit. Or idle speed control switch or circuit(shorted). good luck One tip on the Idle Air system on GM's - some need to have a special reset on that part to clear the code. On the 1980-1990's GM's the procedur…e was to drive the car at a speed exceeding 50 mph for a minimum of five minutes, continuous. You will need to make sure the car stays above 50 for the full five minutes. Make sure to find a nice stretch of open highway where the legal speed will let you do this. This will cause the computer to push the idle air system wide open, then fully closed, to check it over the whole range. After this you can clear the codes and the code should not come back. If it does, cleaning of the intake may help, since dirt in the passages can affect this system also. (MORE)
if it is OBDII hook it up to the tester which can be done for free at advanced auto parts. Advance auto parts in my area will no longer clear codes for you.
Without a code reader (you can buy one for about $80 at most auto parts stores), you can sometimes erase the codes by disconnecting the battery cables. Most newer code readers allow you to erase the computer memory.
P0302 means number two cylinder has a misfire, due to possibly a spark plug, spark plug wire, ignition coil, fuel injector or something mechanical in the engine like a bad valve, valve spring or piston ring etc. For future reference OBD II codes are listed at DenLorsTools.com Tech articles under OBD… II codes and scan tools.. Answer . P0302 is a Cylinder Number 2 Misfire. Start at the front of the engine, where all the accessories are mounted(alternator, power steering pump, etc) then count each each spark plug from left to right in normal order. The cylinder to the left will be 1, and the cylinder to the far right will be 4. When you locate number 2 cylinder, check the plug wire for damage. remove the spark plug and inspect it for wear. A new set of spark plugs and wires will probably fix your problem. Otherwise it may me a coil pack or ignition module. Hope this helps.. Answer . It means the for some reason cylinder #2 isn't firing properly. That is usually a spark plug, plug wire, or ignition coil issue. But at times, I have found that an internal problem in the cylinder, like a valve sticking. I have also had a fuel injector cause this. Commonly too, on engines with individual EGR ports, one to each cylinder, I have had restricted EGR ports do this, in a situation where all but one was restricted. I would start with the easiest and most common fix, plugs and wires, and go from there.. (MORE)
Your check engine light came on in your 1999 Dodge Neon you checked the PCM codes and the one that is flashing in your car is not in your repair book what does code 45 mean?
There is no such code on an OBD2 vehicle which this 1999 Neon is. Each code has a unique letter and four numbers that correspond to a specific fault. The letter can be a B (body), C (chassis), U (network), or P (power train). Practically speaking, just about every code you'll have to deal with will …have a P prefix, but the proliferation of electronics means that the others may come up. A code 45 is an OBD1 code which you will not receive from this OBD2 vehicle. (MORE)

Actually, there are two coolant temperature sensors. One is for the gauge and the other tells the ECM [computer] what the coolant temperature is. If your gauge is reading normal, that sensor is probably OK. It is likely the other sensor is giving false info to the ECM which is turning on the light a…nd showing a code P0128. If it is sending a reading that is too low, the ECM demands more fuel from the injectors [usually resulting in poor fuel mileage]. If it is sending a reading that is too high [overheating] the ECM says to lean out the fuel mixture. The vehicle would then be very difficult to start and drive when cold until completely warmed up. False readings somewhere in the middle will give combinations of both symptoms. Good answer, interesting point. I'd just add that the basic meaning for a P0128 code is: Coolant Thermostat Problem . Usually not getting hot enough in the time given, that is standard. (MORE)

My 2001 Chevy cavalier's check engine light is on and code p0128 came up then i changed the thermostat but the check engine light is still on now what?
the check engine light has to be cleared with the scanner, that wipes out the codes and resets.. Answered by Littlestown Lube & Brake Littlestown, PA 717-359-5022. light will still be on. Black tape on dash light, best solution i can find.
Go to a repair shop and have them diagnosis the problem.. If you live at 2000 feet or more the check engine light will come on due to the oxogen. amount at higher altitudes.
Code PO102 is referring to the mass air flow sensor. The maf sensor tells the computer how much air is being taken ino the engine so it will know how much fuel is required. You need to check for any vacuum leaks or loose clamps on the air intake hose.

Get the code, then google it. You will find a lot of potential solutions, try them in order of least expensive to most expensive.

you have to give us the make and model of car or go by a auto parts store. They can tell you
it is low coolant temperature, could be the thermostat could be thesensor for coolant temperature.
Engine coolant Temperature ( ECT ) sensor does not meet minimum thermostat regulating temperature. Need to replace ECT sensor. Make sure engine is COLD before changing. The sensor is on the right head back beside the last spark plug.
OBD11 DTC definitions PO-456 EVAP emmission control system leak (very small) possibly faulty purge valve
O2 sensor circuit malfunction (sensor 1). I got this directly out of the Haynes Repair Manual, so I personally suggest you replace your Oxygen sensors.
It means you have an Evap purge control leak in the EVAP system. Basically when you have gasoline in a car there are a lot of excess fumes, these fumes are routed through the EVAP system of the car, through a charcoal canister, and returned back to your gas tank as liquid fuel. A leaking charcoal… canister, Evap Purge solenoid, PCV lines or PCV elbows can cause this. Also a leaking gas cap can cause this. I would recommend replacing the gas cap first. if that does not do it, check all the connections to the EVAP canister *located in the engine by the firewall*. If there are any leaks, change the elbows or lines. IF the problem still exists you most likely need a new charcoal canister or Canister purge valve solenoid. (MORE)
Disconnect positive battery cable and step on the brake the after 10 mins reconnect the battery cable andthe computer will be reset
Evap control systems are often times difficult to diagnose. Try using information here:. http://www.gearchatter.com/viewpost17788.php. If that is more than you want to deal with you may want to take it to a good mechanic.
This code is different from manufacturer to manufacturer. I need to know what kind of car this is to tell.

First off they didn't even make a 2003 KIA sportage yeah I know alot about cars especially KIA itself.
Engine thermostat malfunction, temp below normal range. . Basically the engine is not warming up fast enough.
P0128: Engine Coolant Temperature is below the Thermostat Regulating Temperature Basically the Computer sees that the engine is running too cold. It could be that the thermostat is stuck open and the engine is actually too cold. Or it could be a bad temperature sensor, wiring to the sensor, …or the PCM (computer) has a problem and is making a mistake. I would probably replace the thermostat and ECT (Engine Coolant Temp) Sensor first because both are inexpensive and relatively easy to change. (MORE)
You will need a code reader. Your local auto parts store can sell you a simple one for $60 to $80. It will come with directions and a book of code definitions.

This code indicates an incorrect Evaporative System Purge Control Valve flow. Can be caused by clogged, disconnected, or broken vacuum line between the EVAP Canister Purge Valve and intake manifold or bad Purge Valve itself. .
p0128-- coolant temperature below thermotat regulating temperature---change thermostat first, and make sure coolant is ok!! then if it does not work. change coolant temperature sensor.
The code means that EGR flow is insufficient. That probably means the EGR valve is stuck partially open or the EGR pump is not working correctly. You probably need to get it repaired before too long or it will dirty up your engines interior pretty bad. If you know of a good independent mechanic, it'…s a pretty easy fix and he will probably have an online source to get the parts a little cheaper. The dealers get pretty proud of these repairs and you are probably looking in the neighborhood of 300-500 dollars for the repair. (MORE)

O 2 sensor stuck lean This is usually caused by an exhaust leak, misfire or badly out of calibration fuel injection system. The code usually shows up alone as the computer ignores this problem if it sees a misfire and brings up that code instead.
P0128 means that the engine is not getting up to proper operating temperature. Basically means it is running too cool. It could mean that the thermostat is stuck in the open position, and sometimes (through research) it could even mean that the coolant level is too low. It is OK to drive, but it mig…ht run a little rough at times, and it should be checked out fairly soon. (MORE)
PO447 indicated a leak in the EVAP emissions system. First thing to do is check to make sure the gas cap is tight. Also check the seal on the cap. If that is good and the cap is tight then you have a problem somewhere with the hoses or the purge valve.
this means the car has a problem mechanicly an needs fixing, most garages carry out this test between 10 or 20 quid then re-test to see if problem still there allternatively take lead off batry for 20 mins, this should reset codes an turn lights off.
Large leak detected. 1 of 4 things: 1. Defective, loose, or missing fuel cap. 2. Evap canister is broken, hose cracked or disconnected. 3. Purge or vent solenoid defective. 4. Vacuum leak at engine.

Not enough info to answer. Codes are either two digits( pre 1996) or four digits (1996 and later). Also it is a huge help to include the year, make, and model
It is a code that is set by the ECU (computer) that tells you what part of the emissions system on the vehicle that has a problem. The code is retrieved with a scan tool. Most auto parts stores will retrieve the code for you free of charge. Remember, the code only tells you what part is being effect…ed not necessarily the defective part. Do not just throw parts at the problem unless you know exactly what you're doing. (MORE)
The check engine light error code PO172 means that the system is too rich. The reason why the system is to rich is due to the mass air flow sensor being dirty or faulty.
