FamilyPowertrain (P)

Typical symptoms

Engine will not start
Sudden stalling while driving
Stuttering start
Tachometer dropping to zero while driving

Common causes

Faulty or loose sensor
Damaged reluctor ring or metal debris on it
Wiring chafed near the engine block
Connector contaminated with oil
Air gap between sensor and ring out of tolerance

What to do

Deal with this before it strands you. The sensor is cheap, but check the wiring and connector first: engine heat destroys insulation, and a wire touching ground gives the same code.
