Section 2.24
Air Intake Pressure Sensor

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

Figure 1. 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.‪

Section 2.24.1
Replacement of Air Intake Pressure Sensor

The AIP sensor is non-serviceable and must be replaced as an assembly. No adjustment is required.‪

Section 2.24.2
Removal of Air Intake Pressure Sensor

Remove the AIP sensor as follows: ‪

  1. Disengage the locking tang on the AIP sensor connector body. Grasp the terminal body and gently pull it from the sensor.
  2. Remove the AIP sensor from the intake manifold.

Section 2.24.3
Installation of Air Intake Pressure Sensor

Install the AIP as follows:‪

Note: The AIP sensor is an electronic device. Use care during installation.

  1. Install the AIP sensor into intake sensor manifold. Torque to 2.4-3.0 N·m (21-26 lb·in.).
  2. Engage the locking tang on the AIP connector body.
  3. Turn the ignition to the ON position. Observe the DDR for any diagnostic code(s). If any code(s) other than code 25 is logged, refer to the Detroit Diesel Single ECM Troubleshooting Manual (6SE497).
