DESCRIPTION
The oxygen sensors for the 2.7L V6 (Delta) engine have been changed to a different type. The tables below provide the production change dates and oxygen sensor properties.
The O2 sensors, wiring harness & ECM are NOT Interchangeable.
PRODUCTION CHANGE DATES
| Model | Effective Production Date |
|---|---|
| Santa Fe (SM) V6 | August 4, 2002~ |
| Sonata (EF) V6 | August 16, 2002~ |
| Tiburon (GK) V6 | January 1, 2003~ |
OXYGEN SENSOR PROPERTIES
| Oxygen Sensor Properties | Previous (SM V6 before 8/4/02) (EF V6 before 8/16/02) (GK V6 before 1/1/03) | New (SM V6 on or after 8/4/02) (EF V6 on or after 8/16/02) (GK V6 on or after 1/1/03) |
|---|---|---|
| Sensing Material | Titanium | Zirconium |
| Sensor Operating Range | 0 - 5 V | 0 - 1 V |
| Sensor Principle | Variable Resistance | Voltage Generating |
| Lean Mixture | 5 V | 0 V |
| Rich Mixture | 0 V | 1 V |
NOTE:
- Do NOT attempt to change the O2 sensors from one type to the other on a vehicle.
- The O2 sensors, wiring harness and ECM related to this change are NOT Interchangeable.
- If a vehicle was originally equipped with Titanium O2 sensors, Zirconium O2 sensors cannot be installed. Please refer to the production date information to confirm which type of sensor applies.
- If a vehicle was originally equipped with Zirconium O2 sensors, Titanium O2 sensors cannot be installed. Please refer to the production date information to confirm which type of sensor applies.
OXYGEN SENSOR CONNECTOR INFORMATION
The O2 sensor connectors of the Titanium and Zirconium O2 sensors are different to prevent installation of the incorrect sensor type.
- If the O2 sensor connectors require abnormal force when attempting to connect the wiring harness to the sensor, the incorrect sensor is being installed.
- Although the connectors are different, if abnormally high force is used, it may be possible to improperly force the connectors together. This will result in a comeback with the Check Engine Light ON for O2 sensor codes.
- If the correct sensor is connected to the correct harness connector, the connectors slide together easily, and only require normal effort to secure the locking clip.
- If abnormal resistance is felt when connecting the sensors, refer to the production change information in this TSB as-well-as the photos in this TSB, which indicate the differences between the previous & new sensor types and connector designs to confirm that the correct sensor is being installed.

WARRANTY INFORMATION
Normal warranty applies.
The contents of TSB 03-36-003 , OXYGEN SENSOR LOCATION AND ENGINE BANK TERMINOLOGY - CLARIFICATION, are included below for reference:
DESCRIPTION
The picture below explains the following terms:
- Engine BANK
- Up = Sensor 1 = Front = Closest to the exhaust manifold = Before the Catalyst
- Down = Sensor 2 = Rear = After the Catalyst
- Bank 1 is toward the Dash Panel
- Bank 2 is toward the Radiator
The following O2 Sensor EXAMPLES show how to interpret the terminology:
- B1/S1 = Bank 1/Sensor 1 = Dash Panel Side, BEFORE the catalyst
- B2/S2 = Bank 2/Sensor 2 = Radiator Side, AFTER the catalyst
