Please discard all paper copies of ITB98-008.
SERVICE INFORMATION
If a 1997 I30 has a MIL "on" and DTC P0136 rear O2 sensor stored in the ECM, refer to Figure 1 to identify the rear O2 sensor configuration. Use the
diagnostic information in this bulletin to help determine the cause of the DTC and to determine if it is necessary to install the available countermeasure
exhaust kit. This kit upgrades the rear O2 sensor and exhaust to 1998 specifications by repositioning the O2 sensor to minimize any damage to it as a
result of exhaust moisture contacting the element.
SERVICE PROCEDURE
Examine the rear O2 sensor placement in the exhaust system and compare it to Figures 1a and 1b.
A.
If the vehicle has the original configuration (as in Figure 1a), install the countermeasure exhaust kit.
B.
If you diagnose that the O2 sensor is not operating correctly, and it is necessary to replace the 02 sensor in a vehicle that has already been
upgraded with the countermeasure kit (as in Figure 1b), be sure to use the 1998 P/N referenced in the Parts Information section at the end of
this bulletin.
CAUTION:
The 1997 O2 sensor P/N will not fit in a vehicle with the revised sensor configuration from the countermeasure exhaust kit.
Original Exhaust Kit Removal (see Figure 1a)
1.
Remove the protective shield below the catalytic converter (save the shield and bolts for reinstallation).
2.
Remove and discard the rear O2 sensor and sensor protective side shield. Disconnect electrical connector through the grommet.
