The Series 60G Air Intake Pressure (AIP) sensor is threaded into the intake manifold. See Figure 27856 . The Series 60G natural gas engines use a wide range sensor that allows pressure measurement under conditions of either manifold vacuum or boost.

Air Intake Pressure Sensor Series 60G Engine
This device is a pressure sensor that sends an electrical signal to the ECM. The ECM uses this information to compute the amount of air entering the engine. Fuel supply is regulated by the AIP sensor information to control engine air fuel ratio. The AIP sensor information is also used to control ignition timing.

The AIP sensor is non-serviceable and must be replaced as an assembly. No adjustment is required.
Remove the AIP sensor as follows:
Install the AIP as follows:
Note: The AIP sensor is an electronic device. Use care during installation.
