EMISSIONS RECALL TO REPLACE YOUR VEHICLE'S OXYGEN SENSOR AND CATALYTIC CONVERTER
Dear Jeep Vehicle Owner:
It has been determined that some 1990 Jeep. Cherokee, Comanche and Wrangler vehicle equipped with a 2.5L engine, may be in violation of California
Emissions Standards.
The Problem is...
The oxygen sensor and catalytic converter 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. Driveability could also be adversely affected.
HC emissions consist of unburned fuel that is released into the atmosphere. HC in combination with NOx in the presence of sunlight, can cause the
formation of ozone. CO emissions are formed by the incomplete combustion of fuel. These pollutants are the primary components of smog.
What you must do...
^
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 this1 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 don't get this done...
The State of California requires the comoletion of emission recall repairs prior to vehicle registration renewal. In addition, the State requires that every
vehicle must pass an emission test (SMOG Check) every two years and before it is sold. Without the free service we are providing, your vehicle may be
more likely to fail this test and require that you make costly repairs.
