Defect

On turbocharged vehicles, the engine control computer's fault detection threshold for the intake manifold pressure sensor is set incorrectly. At high altitudes or other low-atmospheric-pressure environments, the system may falsely detect a sensor fault during deceleration. If the vehicle continues to be operated in this condition, the engine warning light may illuminate while driving and the electronic stability control system may cease to function.

Corrective action

On all vehicles, reprogram the engine control computer with the corrected software.
