• If any signs of water and/or corrosion was found on the ambient air temperature
sensor wiring harness (1), it must be replaced.
• If water and/or corrosion was found at the X119 connector (5), the main body wiring
harness connector must be replaced.
• If water and/or corrosion was found at the B9 connector (2), the ambient air

technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
