Condition
Some customers may comment that the fuel gauge is erratic (does not go to Full or moves off Full too quickly).
Cause
This condition may be caused by the Powertrain Control Module (PCM) calibration.
Correction
Important: The Exhaust Gas Recirculation (EGR) valve may need to be updated before reprogramming the PCM. Refer to Corporate Bulletin Number 06-06-04-002A to determine which type of EGR valve is on the vehicle being serviced.
Technicians are to reprogram the PCM with an updated calibration using one of the following procedures:
| • | On 2006 model year vehicles built with the 3.5L (LX9) engine and a Delphi EGR valve, replace the original Delphi EGR valve with the new Siemens EGR valve kit (P/N 89018175). Install the new Siemens EGR valve, tube and harness connector. Refer to Corporate Bulletin Number 06-06-04-002A and then reprogram the PCM using the updated calibration. |
| • | On 2006 model year vehicles built with the 3.5L (LX9) engine and a Siemens EGR valve, do not replace the EGR valve - just reprogram the PCM using the updated calibration. |
Refer to the Engine Control Module Programming and Setup (3.5 or 3.9) procedure in SI for more information.
The new PCM calibrations were made available to dealerships as part of TIS2000 incremental satellite update version 1.5, which was broadcast to dealers January 23, 2006. As always, make sure your Tech 2® is updated with the latest software version.
