CABLE AS 1495092 - Caterpillar

Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below. Problem
The existing intake manifold air temperature sensor can fail do to both water and contamination through the harness connector.Solution
Replace the 274-6718 Pressure Sensor Gp with the 299-3956 Pressure Sensor Gp and replace the ladder clip with a 183-4274 Bracket to hold the interface connection between the external harness and the pigtail sensor. These modifications can be made using the existing external harness.The removal and installation procedure for the new sensor assembly is shown below.Required Parts
