NHTSA Recall 94V032000 — Mack Vehicle Speed Control

What's wrong

FUEL INJECTION SYSTEM RECONFIGURATION TO COMPLY WITH ENGINE EMISSION STANDARDS CAUSE HIGHER ENGINE VIBRATION LEVELS WHICH LEAD TO EARLY WEAR AND COMPLETE FAILURE OF THE SECONDARY THROTTLE RETURN MECHANISM.

The risk

IN THE EVENT THE PRIMARY THROTTLE RETURN FAILS, FAILURE OF THE SECONDARY THROTTLE RETURN SYSTEM WOULD NOT PROVIDE PROTECTION AGAINST LOSS OF THROTTLE CONTROL.

The fix

A NEW PRODUCTION SECONDARY THROTTLE RETURN SYSTEM CONFIGURATION WILL BE INSTALLED.

SYSTEM: FUEL; FUEL PUMP.VEHICLE DESCRIPTION: CLASS 8 TRUCKS EQUIPPED WITH E6 AND E7 ENGINES WITH ROBERT BOSCH P7100 MECHANICALLY-GOVERNED FUEL INJECTION PUMPS.NOTE: IF YOUR VEHICLE IS PRESENTED TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND THE REMEDY IS NOT PROVIDED WITHIN A REASONABLE TIME AND FREE OF CHARGE OR THE REMEDY DOES NOT CORRECT THE DEFECT OR NONCOMPLIANCE, PLEASE CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S AUTO SAFETY HOTLINE AT 1-800-424-9393.
