Vehicle Speed Sensor: Initial Inspection and Diagnostic Overview
PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
^
Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a
continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be
checked by monitoring for a voltage drop with the system operational (under load).
^
Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (Refer to General
Troubleshooting Procedure). See: Diagrams/Diagnostic Aids
