Cobalt L4-2.0L SC VIN P (2005)
Customer Notification
General Motors will notify customers of this special coverage on their vehicles (see copy of typical customer letter included with this bulletin - actual
divisional letter may vary slightly).
Service Procedure
The purpose of this field action bulletin is to determine if it is necessary to replace the catalytic converter on certain 2004-07 model year Saturn ION Red
Line and 2005-07 model year Chevrolet Cobalt SS vehicles, equipped with 2.0L 4-cylinder (RPO LSJ) engine. The catalytic converter is an emission
control device added to the engine exhaust system in order to reduce hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx)
pollutants from the exhaust gas.
All diagnostics on a vehicle should follow a logical process. Strategy Based Diagnostics is a uniform approach for repairing all systems. The diagnostic
flow is the place to start when repairs are necessary and may always be used in order to resolve a system problem. For a detailed explanation, refer to
Strategy Based Diagnosis in SI.
Determine the condition of the catalytic converter. Refer to Symptom - Engine Exhaust and Restricted Exhaust in SI.
-
If diagnosis indicates that the catalytic converter must be replaced, replace the Catalytic Converter. Refer to Catalytic Converter Replacement in
SI.
-
If diagnosis indicates that the catalytic converter does NOT require replacement, determine the cause of the customer-reported exhaust concern
using the diagnostic service information in SI. Diagnostic time and service repairs for exhaust system components other than the catalytic
converter are NOT covered by this field action. Diagnostic time and service repair work for exhaust system components other than the catalytic
converter must be billed under warranty or customer pay.
