SOURCE: service engine light staying on

Hello tdamm...No...the service engine soon (SES) light on your yukon is not telling you to change the oil.
This is a warning light that is illuminated when there is a problem affecting the Emission system and the engines computer management (ECM) has detected it from a fault. It could be something as simple as a loose or defective gas cap. If the SES light is blinking, it's more serious....
The yukon needs to be connected to diagnostic equipment (scanner) for fault diagnosis.
You can go to autozone they will hook up an OBD II scanner to your vehicle and explain the codes to you.
Good luck...i hope this helps and will fixya up.

SOURCE: How do i clear the "service engine soon"

Disconnect the battery for a minuit and turn on the light's to power down any electrical power. Reconnect the battery and that should clear the "servie engine light soon",but if there are any DTC codes, the "Service engine light" will come back on.
On board diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection so you can generally retrieve the codes yourself. No need buying a scanner or running to any parts stores to check the Engine Light. This system is called obd1 and applies to most vehicles made before 1995 for domestics and 1993 on imports.

For GM domestic vehicles made before 1995, the diagnostic connector is located under the dash panel by the driver side. To get the check engine codes to flash in your dash panel, use a jumper wire or a paper clip and connect terminals A and B of the diagnostic connector. Turn your ignition key on with engine off and the codes should start to blink. All codes should start with code 12 which is one long flash followed by 2 short flashes. This code 12 means the diagnostic system is normal and will repeat itself continuously if there are no trouble codes. Otherwise, code 12 will flash 3 times before flashing the fault codes.

the codes can be erased or cleared by disconnecting the battery negative terminal for 1 minute and reconnect. Just make sure to check your service manual in case you have electronic equipment such as radio or clock that needs reprogramming in which battery disconnection is not recommended. Finally after performing repairs on the culprit code, always go for a road test to confirm if the problem is fixed.

Good luck and hope this help, here is a link to the DTC codes. http://www.gmtuners.com/OBD1_DTC.htm

Wheel speed sensors misadjusted, damaged , or metal shavings and other debree, since they are magnetic can give false readings from one of the wheel circuits. Over sized tires can give of false speed readings as well. there are many other causes including bad relay, control module, e.t.c. It is best to have the proper scan tool to diagnose an ABS problem

I replaced intake manifold on 1998 gmc serria 1500 5.0 liter it got rid of the erratic idling but now if I go above 50 mph I have a loud whining and the engine service light flashes on and off if i let off...


get the failure codes! flashing "service engine soon" lamp means you are damaging your catalyic converters. you could have restricted converters also either too lean fuel mix or or too rich fuel mix. the only other way the lamp flashes is if the engine is misfiring. bottom line, get the codes first so i can help further. the codes will lead you to the problem. it will not necessarily tell you what the problem is.

Service Soon light is on.. what does that mean?


In most cases the light will go out by itself once the problem is resolved that made the light illuminate. You can RESET the light by removing and re-installing the fuse(s) marked as ECM in the fuse panel or by disconnecting the battery for several seconds.

If the light continues to illuminate, You will need to extract the computer codes from the computer via the factory specifications to see what code(s) are being stored in the computer.

NOTE: Disconnecting the battery will cause the engine to run a little erratic until you drive it for several miles so the computer can re-learn it's proper settings.
