Question about 2002 GMC Yukon Denali

1 Answer

The Message Center on my 2002 GMC Yukon XL is giving false readings. It is telling me to check the oil and check the fluid level. I have had both of those items checked and they are fine, the oil pressue is fine. The check oil light stays on most of the time and the check fluid light is infrequent. I am a widowed mother with 3 children and really need to try to repair this myself. Our finances are more than tight. I am hoping this is an easy fix and someone could help me determine where and what it is that I need to change out. I was told it is porbably sensors? Thanks in advance, Diane in Woodstock, GA

The oil level sensor is located in the oil pan. There should be a yellowish/brownish plastic looking large diameter nut sticking out the side of the pan with some wires going to it. Unplug those wires and see if the message goes away. If it does then don't worry about it until you have the means to do so. Just monitor the oil level ever thousand miles or so.

The senors are pretty reasonable priced and available form the dealer. They are threaded into the pan and a medium sized crescent wrech is all you really need to remove and install.

EBCM


No, absolutely not, although the EBCM might possibly be the problem, it is a costly item and 95% of the time is replaced for nothing. Make sure to get the system diagnosed properly, if he can't get a reading from the diagnostic machine, check the abs (EBS) fuse(s), it (they) might be burnt. Then check for fluid level and fluid leaks in the brake system. If these are OK, get the wiring checked to the EBCM for powers, grounds, and data (diagnostics).
