Vehicle Speed Sensor: Initial Inspection and Diagnostic Overview

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS

1. Check for a broken (or partially broken) wire inside of the insulation which could cause system failure 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).

2. Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems. (See General Troubleshooting

Procedures.)  See: Diagrams/Diagnostic Aids
