Service bulletin 25-002-14

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Malfunction Indicator Lamp Illumination Due To Oxygen Sensor This bulletin involves the installation of an Oxygen (O2) Sensor Overlay Harness for any Oxygen Sensor related DTC(s). The Overlay Harness will consist of twelve 18 AWG wires (six from each Oxygen Sensor) that run to a new Oxygen Sensor Module connector. Four wires will be removed from the original vehicle O2 Module connector and installed in the new overlay harness O2 Module connector.Do NOT replace any parts prior to performing this bulletin and the Verifications test below. If the vehicle has any of the following DTC?s for O2 Sensors, Stored, Pending or Active, perform the Repair Procedure. P013A O2 Sensor 1/2 Slow Response - Rich To Lean (Soot related code, see note). P013B O2 Sensor 1/2 Slow Response - Lean To Rich (Soot related code, see note).
