What It Helps Address

• Hard starting or extended crank time caused by a weak crankshaft signal
• Intermittent stalling related to inconsistent engine speed input
• Rough idle or hesitation tied to timing signal errors
• Check engine light conditions associated with crankshaft position sensor faults
• Misfire or drivability complaints when the engine control module loses accurate crank data

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a female connector with three male terminals, one connector, and one mounting hole. Confirm the vehicle application by year, make, and model before service, especially on 2022 Silverado 1500 LTD and Sierra 1500 Limited applications where fitment details differ from standard model naming. The part number 235-2373 should be matched to the original sensor configuration before replacement.
