Fault Codes Requiring Diagnosis

• 0717 - Y3/8n1 turbine speed sensor signal unavailable.

• 2767 - Y3/8n2 internal speed sensor signal unavailable.

Diagnose the transmission and affected sensor before replacing parts. Control faults or intermittent operation do not prove that the sensor alone is responsible; inspect connections and traces of overheating or contact wear.

Contents, Material and Repair Scope

Supplied as a set of two speed sensors. Listed material: plastic. Installation location: automatic transmission. These are replacement sensors, rather than a complete transmission or VGS control assembly.
