EMISSIONS RECALL TO REPLACE YOUR VEHICLE’S OXYGEN SENSOR AND CATALYTIC CONVERTER
Dear Jeep Vehicle Owner:
Chrysler Corporation has determined that some 1989 and 1990 Jeep Cherokee, Comanche and Wrangler vehicles equipped with a 2 . 5L engine, may be in violation of Federal Emissions Standards.
The Problem is..
What you must do...
The oxygen sensor and catalytic convener on your vehicle (identified on the enclosed form), may be susceptible to failure. This could result in hydrocarbon (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) emission levels above the allowable limits, which were established to protect the public health from the dangers of air pollution.
Simply contact your Jeep dealer to schedule a service appointment. Ask the dealer to hold parts for your vehicle or order them prior to your appointment.
Bring the enclosed Owner Notification Form with you to your dealer. It tells the dealer what service is required for your vehicle.
What Chrysler and your dealer will do.
Chrysler will repair your vehicle free of charge .(parts and labor). To do this, your dealer will replace the oxygen sensor and catalytic converter. The service will take about one hour but additional time may be required depending on how service work is scheduled and processed.

If you have trouble getting your vehicle repaired, please call the Chrysler Customer Center, toll free, at 1-800-853-1403. A representative will assist you in getting your vehicle repaired.

In order to ensure your full protection under the emission warranty made applicable to your vehicle under Federal law, and your right to participate in future recalls, it is recommended that you have your vehicle serviced as soon as possible.
