The turbocharger speed sensor is located on the top of the turbocharger between the compressor and the turbine housings. INSITE™ electronic service tool can be used to monitor the sensor for proper operation.
Inspect the turbocharger speed sensor body for signs of melting or damage. If signs of melting or damage are found on the sensor, inspect the turbocharger coolant supply for restriction.
If the turbocharger speed sensor is being removed due to an oil leak, inspect the turbocharger speed sensor o-ring for signs of damage. If the o-ring is cut or damaged, the o-ring must be replaced.
If there are no cuts or damage evident to the o-ring, it is possible to reseal and prevent oil leaks. To do this, apply Loctite™ 5699, or equivalent, to the o-ring and the area where the o-ring sits on the speed sensor, prior to assembly.
If installing a new turbocharger speed sensor, make sure the new turbocharger speed sensor has a new o-ring installed.
If the turbocharger speed sensor was removed due to an oil leak, it is possible to reuse the turbocharger speed sensor and either replace or inspect the o-ring for reuse (as described in the Inspection section above).
Apply Loctite™ 5699, or equivalent, to the o-ring. This helps seal and prevent oil leaks.
Install the turbocharger speed sensor into the engine. Tighten the capscrew that holds the speed sensor in place.
