I don't know what problem you're trying to diagnose or
the year of the truck. But I do know that the new style internationals, have known computer issues.
ie. speedodemeter not accurate/rt headlight out/cruise ctl. quits/some gauges quit/fuel transfer pump sucks the feed tank, to the point it dumps fuel in the street until you notice it or it runs out of fuel.
These are just a few of the more memorable ones.
And it starts out intermitent,and never all at once.
Start by checking the connections for the computer.
This worked on 3 of the trucks. The rest I sent to
international, were they sat waiting for computers.
I hope this helps Good luck.

What is service engine light code 12 mean



READING CODES USING MIL (CHECK ENGINE) LAMP

Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.

  1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
  2. Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.

The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:


Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46. Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.

Is there an ALDL port on a legend ...to plug in a scan tool


There is a connector but it is not like the connector used in the newer 1996 OBD2 cars, your year uses OBD1, here is how you check for codes in this car.

Acura OBD1 Codes Retrieval
Acura vehicles 1986-95 obd1 code retrieval
There are a few different ways to retrieve the codes for "check engine light" for Acura vehicles. One method is to use a led light (sometimes 2 led lights) on the computer or controller box itself. If it has 2 led lights, the color is red and amber. The red is used for flashing the codes whereas the amber is used for adjustment. If you have only a single led light indicator, then that is used for flashing the code.
The controller box can be found by lifting the carpet of the passenger side front foot well or floorboard. You can see the led lights without removing the controller. On other models, you can find the controller under the driver or passenger front seat.
The second way to get the code is using a jumper wire on the diagnostic connector located on the kick panel at the front passenger side. You then watch the codes being flashed at the dash panel after you turn the key on. To read the code being flashed is easy. Example: Code 23 is 2 long flashes followed by 3 short flashes. A longer pause separates the next code that follows.
Here are Acura vehicles 1986-95 general codes:
Code 0 Electronic control unit (ecu)
Code 1 02 (oxygen) sensor
Code 3 and 5 map sensor
Code 4 Crank angle sensor
Code 6 Coolant temperature sensor
Code 7 Throttle angle sensor
Code 8 Crank angle sensor (TDC)
Code 9 Crank angle sensor (CLY)
Code 10 Intake air temperature sensor
Code 12 EGR system fault
Code 13 Atmospheric pressure sensor
Code 14 Electronic air control valve
Code 15 Ignition output signal
Code 16 Fuel injector fault
Code 17 Vehicle speed sensor
Code 21 Spool solenoid valve
Code 22 Valve timing oil pressure switch fault
Code 23 Knock sensor
Code 41 Oxygen sensor heater fault
Code 43 Fuel supply system

We just picked up a 1985 Cadillac Deville with 42,000 original miles. The car had not been driven in 4 years. It was given a tune up, all liquids were changed. When we changed the gas filter there was...


Yes, water could be in the gasoline. Try to run a few tanks of gas through it to clear up that problem.

Are there any engine codes on this car that are readable? Maybe a throttle position sensor is not giving good data to the computer.

BASIC TROUBLESHOOTING
  1. NOTE: The following explains how to activate the Trouble Code signal light in the instrument cluster. Before suspecting the C-4 or CCC system, or any of its components as being faulty, check the ignition system (distributor, timing, spark plugs and wires). Check the engine compression, the air cleaner and any of the emission control components that are not controlled by the ECM. Also check the intake manifold, the vacuum hoses and hose connectors for any leaks. Check the carburetor mounting bolts for tightness. NOTE: For information regarding computer control/troubleshooting of the Electronic and Digital fuel injected vehicles, please refer to Section 5 of this manual. The following symptoms could indicate a possible problem area with the C-4 or CCC systems:
    1. Detonation
    2. Stalling or rough idling when the engine is cold
    3. Stalling or rough idling when the engine is hot
    4. Missing
    5. Hesitation
    6. Surging
    7. Poor gasoline mileage
    8. Sluggish or spongy performance
    9. Hard starting when engine is cold
    10. Hard starting when the engine is hot
    11. Objectionable exhaust odors
    12. Engine cuts out
    13. Improper idle speed (CCC only). As a bulb and system check, the Check Engine light will come on when the ignition switch is turned to the ON position but the engine is not started. The Check Engine light will also produce the trouble code/codes by a series of flashes which translate as follows: When the diagnostic test lead (C-4) or terminal (CCC) under the instrument panel is grounded, with the ignition in the ON position and the engine not running, the Check Engine light will flash once, pause, and then flash twice in rapid succession. This is a Code 12, which indicates that the diagnostic system is working. After a long pause, the Code 12 will repeat itself two more times. This whole cycle will then repeat itself until the engine is started or the ignition switch is turned OFF. When the engine is started, the Check Engine light will remain on for a few seconds and then turn off. If the Check Engine light remains on, the self-diagnostic system has detected a problem. If the test lead (C-4) or test terminal (CCC) is then grounded, the trouble code will flash (3) three times. If more than one problem is found to be in existence, each trouble code will flash (3) three times and then change to the next one. Trouble codes will flash in numerical order (lowest code number to highest). The trouble code series will repeat themselves for as long as the test leads or terminal remains grounded. A trouble code indicates a problem with a given circuit. For example, trouble code 14 indicates a problem in the cooling sensor circuit. This includes the coolant sensor, its electrical harness and the Electronic Control Module (ECM). Since the self-diagnostic system cannot diagnose every possible fault in the system, the absence of a trouble code does not necessarily mean that the system is trouble-free. To determine whether or not a problem with the system exists that does not activate a trouble code, a system performance check must be made. This job should be left to a qualified service technician. In the case of an intermittent fault in the system, the Check Engine light will go out when the fault goes away, but the trouble code will remain in the memory of the ECM. Therefore, if a trouble code can be obtained even though the Check Engine light is not on, it must still be evaluated. It must be determined if the fault is intermittent or if the engine must be operating under certain conditions (acceleration, deceleration, etc.) before the Check Engine light will come on. In some cases, certain trouble codes will not be recorded in the ECM until the engine has been operated at part throttle for at least 5-18 minutes. On the C-4 system, the ECM erases all trouble codes every time that the ignition is turned off. In the case of intermittent faults, a long term memory is desirable. This can be produced by connecting the orange connector/lead from terminal S of the ECM directly to the battery (or a hot fuse panel terminal). This terminal must always be disconnected immediately after diagnosis as it puts an undue strain on the battery. On the CCC system, a trouble code will be stored until the terminal R at the ECM has been disconnected from the battery for at least 10 seconds.

Check engine light comes on


A malfunction indicator lamp (MIL), commonly referred to as the "Check Engine Light" is an indicator of malfunction of the computerized engine management system. It is found on the instrument console of most automobiles. When illuminated, it is typically either an amber or red color. On vehicles equipped with OBD-II, the light has two stages: steady (indicating a minor fault such as a loose gas cap or failing oxygen sensor) and flashing (indicating a severe fault, that will eventually destroy the catalytic converter, such as a misfire). When the MIL is lit, the engine control unit stores a fault code related to the malfunction, which can be retrieved with a scan tool and used for further diagnosis. The malfunction indicator lamp is usually labeled with the text check engine, service engine soon, check engine soon, or a picture of an engine.
The MIL appeared in the early 80s along with computerized engine controls. Even the earliest systems, such as GM's CCC (Computer Command Carburetor) system had self diagnosis functionality. When the computer detected a fault, it illuminated the MIL. Up until OBDII, on most cars the MIL could output codes, when two pins on the ALDL are jumped, the light would flash the codes, for instance (blink) (pause) (blink) (blink) for code 12. Some manufacturers retained this feature even after OBDII, such as Honda.

Hope this help (remember comment and rated this). Good luck.

2005 FORD TAURUS WITH 43,000 MILES...ENGINE LIGHT JUST CAME ON...IS THIS AN IMMEDIATE ACTION ON MY PART?


I think the problem is from the Emission System, something must have gone worng with it. and sometimes it is necessary to check the O2 Sensor as well. But it will be better you scan your car with the computer and so as to know where the problem comes from, so the error code from the scanning will now indicate the repair to be done on your car. Kindly take your car to an Auto Service Center to retrieve the error codes and then ask then to repair it for you or you forward the error codes to us so as to know the best repair to be done on the car. Thanks

Engine block amber light


sounds like your check engine light is on. On 99ish 3 series the check engine light was an amber engine in the instrument cluster. I thought 5 series actually said service engine soon. If you cycle your key the bulb check should illuminate all lights. see if you have a light that says service engine soon, if not, the amber engine, is the check engine light.
