Eighty-Eight Royale FWD V6-3.8L VIN K (1996)
Vehicle Speed Sensor: Initial Inspection and Diagnostic Overview
PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS:
1. Before component replacement, check that system connections are clean and tight.
^
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).
^
Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems. (refer to General
Troubleshooting Procedures.) See: Diagrams/Diagnostic Aids
