service engine light turns on and off with code P0133 gradually ?
2007 Hyundai Tucson 2.7 SE. my service engine light keeps coming on for two days then turns off. But when i start my car again the next day the light comes back on then turns off again that happens gradually . My guess: O2 censor but im not sure how to get the code because the car feels normal any idea. Many thanks Elkarshofy :confused: |
Could be several things:
OBD-II Trouble Code: P0133 Oxygen Sensor Circuit Slow Response (Bank1, Sensor1) |
Hi Tucsonor
Thanks for replay , I hope if you can tell me where is the Oxygen Sensor Located on my Car? |
There are 4 O2 sensors.
https://www.hyundaitechinfo.com/file...1/0336003A.gif Bank 1 is always the side of the engine with cylinder #1. Bank 2 is always the side of the engine with cylinder #2. Bank 1 is the bank of cylinders on the firewall side. Bank 2 is the bank of cylinders on the radiator side. Sensor 1 is the O2 sensor before the cat. Sensor 2 is the O2 sensor after the cat. So the one you want is the sensor BEFORE the cat on the FIREWALL side of the engine. |
Thank you so much NovaResource
