Good To Know

Q: What are the common signs of a failing crank position sensor? A: A failing sensor often causes intermittent stalling, no-start conditions, or a check engine light with a timing code stored, and replacing it is usually straightforward.

Q: Does the battery need to be disconnected before installation? A: Disconnecting the battery is a sound safety practice for electrical work, and the connector should be checked for a firm, clean fit after installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
