Product Description
CUMMINS 5550064 OEM TURBO SPEED SENSOR KIT – ISB 6.7L (2007.5–2012)
The genuine CUMMINS 5550064 turbo speed sensor kit provides the precise turbocharger shaft-speed data required for correct operation of the HE351VE variable geometry turbocharger used on 2007.5–2012 6.7L ISB Cummins engines. This signal is critical for accurate VGT vane positioning, boost control, turbo braking, and engine protection strategies.
If your turbo is setting speed-related fault codes, causing poor turbo vane response, entering derate, or exhibiting fluctuating boost levels, the Cummins 5550064 OEM sensor restores the factory-correct signal quality needed for the ECM to properly manage turbo operation. This kit includes the speed sensor and required installation components.
