Applicable truck models
This diagnostic reference applies to Caterpillar C11, C13, and C15 diesel engines classified under the “All Others” sub-group. These engines are widely installed in Class 8 on-highway trucks from manufacturers such as Peterbilt, Kenworth, and Western Star, as well as in select vocational and off-highway applications. The DTC 0105-03 specifically addresses a high-voltage reading from the intake manifold air temperature sensor, which can indicate an open circuit, a failed sensor, or a wiring fault in the sensor harness. Workshops servicing any truck or machine equipped with these CAT engine platforms should keep this reference on hand.
