Product Overview

The 1791013 is a genuine Paccar oxygen sensor designed for specified Kenworth truck applications. This lambda sensor measures oxygen in the exhaust gases to support engine air-fuel mixture control.

Product Features

The 1791013 oxygen sensor is manufactured to Paccar factory specifications for measuring oxygen levels in engine exhaust gases.

  • Measures oxygen content in the exhaust stream, providing the exhaust-gas information used by the engine management system.
  • Supplies oxygen feedback for air-fuel mixture control, supporting adjustments based on the oxygen remaining after combustion.
  • Designed to operate at the elevated temperatures encountered during normal use within the engine exhaust system.
  • Constructed for exposure to harsh exhaust conditions at the sensor’s operating location within the exhaust assembly.
  • Supports engine emissions control through its exhaust oxygen sensing function, which contributes to the system’s mixture-control information.
