$$ Light Hyundai: P0133-O2 Sensor SLOW? (SUPER SATURDAY 2024!)

Back in November of 2024 I drove 4 hours to Philadelphia for the Annual Super Saturday 2024 Training Event! https://midatlanticaca.org/super-saturday/ My good friend and mentor Keith DeFazio promised that the Training Seminars this year would NOT DISAPPOINT! Gary Smith and Adam Robertson presented two FANTASTIC seminars: "NETWORK NIGHTMARES: Solving the Diagnostic Distress" and "DIAGNOSING GNARLY INTERMITTENT FAULTS" After the Awesome Training event, I had two cars lined up to diagnose on the way back to Central PA. The first one is a 2001 Hyundai Elantra with a persistent "P0133-Oxygen Sensor SLOW Response" code. 3 NEW O2 sensors have been tried with no improvement... Let's see if we can pinpoint the root cause in the parking lot! Turns out to be a FANTASTIC example of why you NEED an OSCILLOSCOPE to avoid being tricked by SLOW SCAN DATA :) IVAN'S PICO WAVEFORMS: https://drive.google.com/drive/folders/17BhbHXlHxKd_DecW5LqMkKGNOjh6e4yT?usp=drive_link Enjoy!
