A misfire condition will trigger the malfunction light to come on. Other engine malfunctions will do it too. Have a diagnostic meter connected to find out how many codes are generated so you will know what other problems may be happening.

Ok as a guess that you have a SUV and you have different air faults. if you are a DYI'er go to an auto parts store and get an error code tool. Harbor freight for $30-50. Hook it to the car and find out which sensor is it calling for. Note, you can reset the check engine light on most tools that are not the cheapest.

O/D light blinks, but with that the check engine light is ON.--- This will make your troubleshooting easier.When the check engine light comes on, and remains on, this indicates that there is error stored in your cars computer.---- Once the computer is scanned, you will get error codes, as per that error code it will point towards faulty part, which is causing the O/D light to blink.-------- Most probably the O/D light blinks, If a problem exists in No. 1 or No. 2 solenoids or speed sensors .
--------------- For car after 1995 it requires OBD2 tool and for car before 1995 it requires OBD1 tool.------- --------- You car will require OBD1 tool.There are very few auto parts store and repair centers who have OBD1 tool.In your case you required OBD1 tool.------ You can just contact local auto-parts store and they will guide you to the nearest store who has OBD1 tool.There you can get your car scanned.If there is error set in your cars computer, then you will receive the error code.As per error code it will point towards the faulty part causing this problem in your car.------------- -------------- The codes which you get is scanning will be mostly any of this following codes:--- DTC P0500 - Vehicle Speed Sensor Malfunction
. DTC P0750 - Shift Solenoid "A" Malfunction
. DTC P0753 - Shift Solenoid "A" Electrical Malfunction
. DTC P0755 - Shift Solenoid "B" Malfunction
. DTC P0758 - Shift Solenoid "B" Electrical Malfunction
. DTC P0770 - Shift Solenoid "E" (SL) Malfunction
. DTC P0773 - Shift Solenoid "E" (SL) Electrical Malfunction
. DTC P1520 - Stop Light Switch Signal Malfunction
. DTC P1705 - Direct Clutch Speed Sensor Circuit Malfunction
. DTC P1765 - Shift Solenoid Valve SLN Circuit Malfunction
. DTC P1780 - Park/Neutral Position Switch Malfunction --------------- Now it all depends on what code you get, as per that you can replace the following part.------- This will help.Thanks.Helpmech.

The first thing I usually do when seeing a malfunction indicator light on, is to have it scanned with an OBD-II scanner available from Sears, Walmart, or a local auto parts store such as Autozone or Advance Auto Parts. Some auto parts stores will scan it for free.

The self-diagnostic system identifies malfunctions of signal systems such as sensors, actuators and wire harnesses based on the input signals received by the ECCS control unit. Various malfunctions are coded and displayed on the control unit by a series of blinking red and green lights. Results of the self-diagnosis are retained in the control unit's memory and are displayed when the mode selector, located on the rear of the control unit, Fig. 122, is switched to the On position. When displaying malfunction codes, the code number can be determined by counting the number of light pulses. The red light represents the first digit of the code, while the green light represents the second digit of the code. For example, a Code 32, would be displayed as three flashes of the red light, followed by two flashes of the green light. Malfunction codes can be translated as follows:

1. Code 11 -- Crank angle sensor circuit malfunction.
2. Code 12 -- Air flow meter malfunction.
3. Code 13 -- Water temperature sensor circuit malfunction.
4. Code 21 -- Ignition signal malfunction.
5. Code 23 -- Idle switch circuit malfunction.
6. Code 24 -- Transmission switch and clutch switch circuit malfunction.
7. Code 32 -- Starter signal malfunction.
8. Code 42 -- Throttle sensor circuit malfunction.
9. Code 43 -- Injector circuit malfunction.
10. Code 44 -- All monitored systems satisfactory.

First thing to check is whether the gas cap is on tightly. If it is, the next would be to replace the gas cap. That solves 90% of these problems.

P0440 is a generic code for Evaporative Emission Control System Malfunction... pretty much for all makes. It takes 1 malfunction to create a pending DTC... at 2 consecutive malfunctions the MIL(Malfunction Indicator Light,Check Engine Light, etc.} Ok, after you fix it, it should take 3 trips to turn off the light, then 40 more to Remove the code from the computers memory

there is a malfunction in the srs system.

the flashing airbag light is indicating a failurein the system and it is flashing a code.

the beeping is coming from the controll module, if the controller detects a malfunction in the airbag warning light than it will beep in place of flashing the light, this is to inform the driver of a air bag malfunction.

the light bulb may be bad or it may have a poor connection even if you saw the light on, the controller said there is a resistance issue in that circuit.

but you still need to have that system check to find out what started the malfunction and commanded the light on.

good luck
