Check Engine Light

Trouble code P0420 means:Catalyst system efficiency below threshold

CODE 23** Indicates that the air temp sensor input is below the minimum acceptable voltage or sensor input is above the acceptable voltage.

The engine code is the 8th digit of the VIN.

1993 is a OBD 1 system so you must pull out the 15A EFI fuse under the hood for at least 30 seconds. Or unhook the battery for the same amount of time.

It depends on which light is on. The check engine, abs, airbag, and traction lights can only be reset with a scan tool after repairing the failure that caused them to turn on. The oil change due message is reset by turning the key to the run position, engine off, and pressing the gas pedal three times.

MID 128 PID 111 has to do with the engine coolant level in the Volvo. It is a code that can be gotten when the check engine light is flashing.

P0456 = EVAP control system, very small leak detected.

Start with checking for a loose gas cap or replacing the gas cap.

Check your gas cap. The check engine light may come on if the gas cap isn't on tight enough.

As for whether a car can pass inspection in Maine this way, I do not know.

You could try to fix this yourself, but that is not advised. At the very least you should take it to autozone or most any other auto parts stores, which will read the code/codes for free and figure out what to do from there.

The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

A check engine light is always caused by the same thing; the computer has detected a fault (some kind of problem) and is instructing you to connect a code scanner to read the code. That's the only way to know WHAT the computer is trying to tell you.

You have the codes checked with a scan tool, and you repair the cause of the code.

Above the gas pedal, under the dash, there is 2 wires with clips that you plug together. Check engine light will flash the codes recorded in the ecu.

Code p1443 is a malfunction in the evap system. It can be a loose gas cap, a bad flow sensor/circuit, a bad evap solenoid/circuit or even a leak in the evap system. The evap system is designed to trap gas fumes escaping from your gas tank/fuel system contributing to pollution. Code 1443 can be fixed by replacing the canister purge selinoid. The cost range is from $47 to $65 if your Ford dealership will match internet pricing. The dealership is the only place to purchase the item. The location is passenger side of engine near A/C condensor. It has 2 air lines connecting at the top and a plug with 3 wires at the bottom. The size is roughly 3 inches in circumfrance, by 4 inches long. It releases air and that's why the check engine light comes on related to the emission system. Once you find the location the part takes less than 5 minutes to replace . You still will have to get the check engine light code deleted from whomever. Autozone will do it for free.

I have a 2002 Galant GTZ - basically the same car. Disconnect the battery cable for a period of time. This will clear out the computer's memory and reset the light. If the light continues to come back on afterwards, then you might want to get it checked. I've done this on my Galant as well as a 1999 Jeep Cherokee and 1999 Dodge Avenger. I think it will work on any car where the engine light doesn't turn off unless externally reset. When I've done it, I've had the battery cable off for as long as overnight and short as 4 or 5 hours. Just depended on when I disconnected it and when I needed to drive it again. May be able to do it for less time. Just need it to be long enough for the computer to lose it's memory. Of course, you'll lose your radio presets as well.

you can only check it and clearit with an OBDII diagnostic scaner

P1390 indicates your timing belt skipped one or more teeth...

Open and read your owner's manual and you will find the answer The check engine light comes on when the computer diagnostic has stored an error code. It can be something as simple as the battery has been disconnected recently or something to do with the emissions controls. One way for you to find out is by checking the codes yourself. IT may help to point you in the right direction. This page gives the procedure and some of the codes. Of course, if none of this means anything to you, you can always have to dealer hook it up to their diagnostics. http://www.allpar.com/fix/80s-codes.html Take it to auto parts store they have the same diagnostic code reader and its a free check..

Emissions problem. Have the computer scanned for trouble codes. Under the dash on the drivers side there is a fuse block and there is a empty spot in the block that has ridges around it. put a spare fuse in it and turn the key but dont start the car and watch the check engine light it will flash the codes. Like Blink----BlinkBlink, which is a code 12 which is a no trouble code.

i know that a secondary air injection is what is known as an air pump and the pump new is 180 dollars at Advanced Auot Parts. But before you replace it try checking the fuse for the pump next to the battery and see if it is blown it is only about 3 dollars. It is in a black box on the left side of the battery right against the passenger side panel.

Have you checked for codes? Have you reset the codes?

That check engine light is trying to tell you that your vehicle has a problem, and what the problem is. It is giving code 24 and code 57. The meanings of these numerically designated codes can be fouond in the repair manual for your car. Get one at your local parts store, usually less than $20.

www.autonostics.com has a diagonstic testing tool (you can purchase for about $25) which simply plugs into a 16-pin socket typically found under the instrument panel. This tool comes with a book which contains a list of code definitons, although I am not entirely certain whether they are applicable to anything other than the tool it comes with.
