View Full Version : Friends Used 1999 DeVille

I have a friend of mine that just got a used 1999 deville. I pulled the following codes off of his computer. The vehicle wasn't running so I don't know if any are current. I'm going to clear and see if any come back.

P0463 Fuel Level Sensor Circuit High Voltage
P0603 Control Module Long Term Memory Reset
P0741 TCC System Stuck Off
P1520 Transmission Range Switch Circuit
P1527 Transmission Range to Pressure Switch Correlation
P1599 Engine Stall or Near Stall Detected
P1602 Loss of EBTCM Serial Data
P1604 Loss of IPC Serial Data
P1605 Loss of HVAC Serial Data

B1341 Air Mix Door Two Movement Fault

Does anyone know if any of these codes...or a combination of them may point to the vehicle ever having a serious problem? My friend says he has a feeling that it may have been in a wreck then fixed, but he's not for certain. I'll post finding after I clear it. If any come back I'll let you know. I'll keep searching the forum for mor info, but if anyone has an idea I'd appreciate it.

Have him try to pull the history from Carfax.
Get the car running.
Clear the codes.
And, see what, if any, codes develop.

Save those codes, you pulled, for future analysis.
