Summary

IT HAS BEEN DETERMINED THAT CERTAIN EMISSION RELATED COMPONENTS OF THE 1989 JEEP EQUIPPED WITH THE 2.5L ENGINE, MAY BE SUSCEPTIBLE TO FAILURE. FAILURE OF THESE COMPONENTS MAY CAUSE THE VEHICLE TO BE IN VIOLATION OF CALIFORNIA EMISSIONS STANDARDS. HYDROCARBONS, CARBON MONOXIDE AND OXIDES OF NITROGEN COULD BE ABOVE THE ALLOWABLE LIMITS, WHICH WERE ESTABLISHED TO PROTECT PUBLIC HEALTH FROM THE DANGERS OF AIR POLLUTION. TO CORRECT THIS PROBLEM, DEALERS WILL REPLACE THE OXYGEN SENSOR, CRANKCASE VENTILATION HOSE AND IF EQUIPPED, THE TRANSFER CASE VACUUM HOSE AND FUEL TANK VENT BOOT. IN ADDITION, THE THE EXHAUST MANIFOLD WILL BE CHECKED FOR AN EXHAUST LEAK NOISE AND REPLACED AS RQUIRED. *TW
