Re: check engine warning light on continious
The easiest way to reset that light is to go to an AutoZone or Advance Auto..and they have the code readers..and they will see what code you have and they will remove the codes from you car computer and reset the light for free..or you can buy a code reader and do it yourself..i hope this helps....Keith

The warning messages can interrupt the display until cleared or reset by the driver. The warning messages are either single cycle, non-resettable, or repetitive warning messages.
The single cycle warning messages display once whenever the ignition switch is turned to the ON position or a fault occurs in a system, and can be cleared by pressing the RESET button. The single cycle warning messages are:
The instrument cluster (10849) carries out a display proveout to verify that all warning/indicator lamps and monitored systems are functioning correctly. When the ignition switch (11572) is in the ON position with the engine (6007) off, the following indicators will illuminate:
CHECK ENGINE/malfunction indicator lamp (MIL).
CHECK GAGE warning indicator.
Charge system warning indicator.
Anti-lock brake warning indicator (ABS).
Safety belt warning indicator (60second proveout).
Air bag indicator.
An indicator is inoperative - CHECK ENGINE/malfunction indicator lamp (MIL)
The first trial. Switch on ignition. The engine oil pressure warning light for thered light. Start and run the engine, warning lights, half a minute later re lit, butthe Yellow state. Repeated tests a few times are so. Turn off the engine. Pull out the dipstick check the amount of oil, the normal. Self diagnosis to connect to the GTl diagnostic instrument, choose 3 E46 chassis models, click on the"test" button, the scanning of the electronic control system of the whole car.After click two times right. Enter the fault code list interface, can be seen in the"KOM combination meter" project. The store has a fault code.then use the obd code reader to check out it.
warning lamp some used for warn low oil pressure, etc. Wtith the bulbs use for most warning light circuit it is hard to determine whether or not the filamente is good. Will be a good idea to replace the bulb. For test the faulty warning lamp, turn the ignition switch to START, this light the warning lamp. I f the light does not come on , disconnect the sender switch lead. . Use a jumper wier to connect the sender witch lead to ground. With the ignition in RUN the warning lamp should light. If the lamp is illuminated replace the sending switch. If the light does not come on,either the bulb is burned our or the wiring is damaged.Use test light for confirm voltage is present at the sensor terminal connector. If there the bulb is bad. God bless you
code p 0654 refers to engine rpm output--circuit malfunction ===causes wiring ---ECM
code p 0650 refers to malfunction indicator lamp(MIL)--circuit malfunction====causes wiring --MIL---ECm
also refers to crankshaft position/cam shaft position sensor bank 1 sensor A --correlation===causes wiring---CKP sensor ---CMP sensor--mechanical fault
The person running the test is an idiot. The OBDII test instrument is not capable of determining if there is a warning lamp failure. It is probably guessing based on voltage level, but lamp resistance does normally vary. The test is supposed to be done visually. Take it to someone else, and they will probably be more competent and pass your car.
There are many yellow lights on vehicles. They can be different on the same make and model of any particular vehicle depending on what option packages your vehicle is equipped with. Your best bet is to look it up in your owners manual. If you do not have an owners manual, I offer this advise: On all vehicles with the warning lamps in the instrument cluster, the yellow lamp are advisory lamps. ie. telling you that there is a malfunction with a system or letting you know that certain systems have been disabled. It is usually safe to operate the vehicle with the yellow warning lamps illuminated long enough to get the vehicle to a repair facility. (Check Engine Lights, Airbag Lights, Low washer Fluid Lights, etc.)The red lamps on the other hand, mean that the vehicle is not safe to drive before the cause of the lamp coming on has been resolved. (examples are the red Brake Warning Lamp, The Engine Teperature Warning Lamp, The Oil Pressure Warning Lamp.)
Since you stated the the lamp is yellow, I would say that it would be safe to drive the car to your local repair facility and ask them about it and get a professional opinion of what to do about it.
Which warning light? Check engine? Traction? Transmission? Can you give me a more detailed description? With a check engine light Autozone will check it for free and give you the code that caused the light to come on. With the code you can troubleshoot and repair.
