Re: Error Code P0133
Here is an clip from www.hmaservice.com about p0133
DTC Diagnostic item P0133 Oxygen Sensor Circuit Slow Response (Bank1, Sensor1) FAILURE CONDITIONS [FOR P0133] The ECM will set P0133 and MIL will turn on if the ECM does not sense the following conditions during two driving cycles: 1.. Over a period of 2 minutes, the ECM must sense a fuel compensation factor greater 85% or less than 95%: 2.. The ECM must make some correction in the air/fuel ratio when: a.. Engine RPM is between 1600 and 3200 RPM. b.. Engine load range is between 1.35 and 3.4 milliseconds. Catalyst temperature is above 372°C (702°F). System is in closed loop. This code indicates the engine air fuel ratio is not being adjusted by the front oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use. -- Gerald Lawson ASE Certified Master Auto Technician ASE Certified Undercar Specialist Hyundai Senior Master Technician Mitsubishi Master Technician "James D Thompson" <jaydeet@inna.net> wrote in message news:3f1f0f19.5544037@news.cis.dfn.de... > I got the little orange light on my 2000 Accent, so I checked and got > code p0133.
