Technical Service Bulletin # 90C51
Date: 941101
Recall - Excessive CO Emissions
Number: 90-C-51
Section: 6E
Date: Nov., 1994
Subject:
PRODUCT EMISSION CAMPAIGN 90-C-51 - HIGH ALTITUDE CO EXHAUST EMISSIONS
Model and Year:
1990 GEO METRO WITH 1.0L ENGINE (VIN CODE "6" - RPO LP2)
(NON-XFi VEHICLES ONLY)
To: All Chevrolet/Geo Dealers
The Administrator of the U.S. Environmental Protection Agency (EPA) and General Motors have determined that certain 1990 Geo Metro vehicles with
1.0L engines (VIN CODE "6" - RPO LP2) may exceed high altitude carbon monoxide (CO) Federal emission standards. This condition applies to
vehicles registered in Colorado, Nevada, New Mexico and Utah (vehicles which have moved to these states from California which are equipped with
RPO YF5 do not require this campaign repair). These standards were established to protect the public health and welfare from dangers of air pollution.
Excess emission of pollutants may cause a vehicle to fail state mandated emission tests.
To correct this condition, vehicles registered in the four affected states will have a redesigned oxygen sensor installed.
