The Turbo Boost Sensor (TBS) is mounted to the intake manifold with two bolts. A rubber O-ring is used to seal the sensor to the manifold. See Figure 24985 .
Turbo Boost Pressure Sensor
The TBS 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. The ECM uses this information to regulate fuel supply and reduce engine smoke.
The TBS is non-serviceable and must be replaced as an assembly. No adjustment is required.
Remove the TBS as follows:
Note: Be careful not to lose the O-ring.
Install the TBS as follows:
Do not overtighten the bolts that mount the TBS to the intake manifold. Damage to the TBS may result. Torque the bolts to no more than 2.4-2.9 N m (21-26 lb in.) torque.
