codes p2761, p0748
work done prior = none
work done to repair = none
tip/donation yes
Buick tech jk
question = I have the service engine soon light on the dash of my 2006
Buick Lucerne. I had it scanned and the codes come up p2761, and p0748.
Also it does not start sometimes. Can you please help with these
problems, i absolutely love this car. Thanks you.
JK:
Thank you for the tip/donation.
These codes are transmission related. There is a common wiring problem that
can cause intermittent no crank or start and these trans. codes. There is an
area under the hood where a main engine harness rubs through and damages
several different wires. This would be the first place to look.
I will send a pic of the area shortly.
Let me know if you do find some damaged wires and need help with the repair.
If wires look OK, then we can check a few other things......

WARNING LIGHTS
Check Engine / Service Engine Soon / SES light
Todays GM vehicles use many sensor, switches, solenoids, and other electrical components to control or
monitor every aspect of the engine.
From controlling the fuel and ignition systems, to monitoring the emissions.
A problem in any of these systems, or subsystems, can cause the check engine light to come on.
The first step in any diagnosis of the check engine light is to get the computer (PCM or ECM) scanned for codes.
Any time this warning comes on, a code is stored in the computer memory along with many data parameters
that were present at the time of the fault.
A simple code reader that can be purchased at any automotive supplier can retrieve these codes. Many of the
large national parts store chains will scan the system at no charge. The code will give an indication as to what
system has / had a problem. The more expensive scanners will also show live data, and allow further diagnosis
by being able to control parts of a particular system.
