The Turbo Boost Sensor (TBS) is threaded into the intake manifold. See Figure 27369 . The Series 50G natural gas engines use a wide range sensor that allows pressure measurement under conditions of either manifold vacuum or boost.

Turbo Boost Pressure Sensor Series 50G
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 TBS information to control engine air fuel ratio. The TBS information is also used to control ignition timing.
The TBS is non-serviceable and must be replaced as an assembly. No adjustment is required.
Remove the TBS as follows:
Install the TBS as follows:
Note: The TBS is an electronic device. Use care during installation.
