2000-2002 ACCENT CHECK ENGINE LIGHT DTC P0133
FRONT OXYGEN SENSOR SLOW RESPONSE
DESCRIPTION:
When diagnosing Code P0133 (Front Oxygen Sensor - Slow Response) on a 2000 - 2002 model year Accent, verify the integrity of the front exhaust
pipe between the front and rear oxygen sensors. A leak in the pipe can affect the ECM diagnostic logic for the front oxygen sensor.
REPAIR PROCEDURE:
1.
Inspect the exhaust front pipe for a possible exhaust leak.
NOTE:
An exhaust leak may be more noticeable if you inspect while a helper temporarily partially restricts the exhaust outlet tip to build back pressure in the
exhaust.
2.
Replace the exhaust front pipe if leak is confirmed and continue with the next step.
