BMW engine light

Comes on if DME engine management system self diagnostic fault detected. Will stay on until codes are called up and memory erased.

With OBD read the code as follows. Turn on ignition key, press accelerator pedal to the floor five times within 5 seconds. The check engine light will remain on for 5 sec , blik off, come on for 2,5 sec, go off for 2,5 sec and fault code will begin to flash. If more than one fault exist 2nd fault code will be separated by 2,5 sec pause. after fault codes there will be a 0.5 sec flash and light will remain off. to read codes again do procedure again.

Canceling of codes. make sure fault code is present (short blink and light goes out for long period), depress throttle pedal for at least 10 sec. read fault codes again and check for code 1444 (no faults stored.)

Check also the following, fuel pump, oxygen sensor, fuel injectors, engine coolant temp sensor, idle speed control valve, mass airflow sensor and too many other things.

I have a 97 Plymouth Voyager 3.0 engine the oil light comes on and keeps dinging for about an hour first thing in the morning and sometimes later would like to know how to fix or at the very least dis

first of all check the oil level in your engine. If is ok,then check whether the oil filter is a correct one . Change the oil filter with the correct filter and follow it for a day and if the problem gone means that the filter was not keeping the oil in a correct quantity and pressure.Also check if the oil pressure is a good one and it keeps working accurately. A simple try as a test but not for long is to disconnect the cable and follow it if there is not any warning comes on then change the oil switch.

In 97 mercury mountaineer, how to turn off "check engine" light

Go to the local parts store, have them check the codes (they will do this for free usually). It will tell you what sensor needs to be checked/replaced. Once the part is replaced, it will clear on its own. They can also reset the code, but it will come back if the trouble persists.
