P0133 Hyundai - Accent 2002 GS

Question

How do you change the oxygen sensor for code P0133 on a Hyundai Accent 2002 GS 1.6 engine?

Answer 1

Hi there,

This code points to the front O2 sensor. This is mounted right in front of the engine in the exhaust manifold. Replacement is simple, disconnect the electrical connector, unscrew the sensor and install the new one. Clear the codes and test drive.
