I just picked up my "new" 98 C-5. I have a "service vehicle soon" message that keeps coming back. I read the codes and I have several History codes, the only current code is p0141, can someone shed some light on cause and remedy? I will clear all the history codes and see which come back.

Thanks

These 2 sites below explain each Code & what to do. I had the same problem with rear 02 sensors after LTs installed, even with 02 Sims, so I finally turned them OFF (using HP Tuners)..

Without long tubes:
replace above referenced o2 sensor (there are 4 total, 2 pre-cat, 2 post cat)

With long tubes:
make SURE that the wiring is all tucked away from the heat. I had codes for over a year I tried everything including new sensors. Finally got a good look under the car and tucked/tied all wires away from pipes and BAM -- no more codes!

Others have not been so lucky and have had to actually turn the codes off.
