How does code P1133 work on an oxygen sensor?
The key to diagnosing and repairing code P1133 is to understand that oxygen sensors do NOT switch by themselves. A fully functional oxygen sensor only reacts, or “switches” from registering a lean-running condition, to registering a rich-running condition as a response to changes in the oxygen content of the exhaust stream.
What are the symptoms of car code P1133?
What are the symptoms of code P1133? 1 Hard starting. 2 Rough, or erratic idling under some conditions that may vary between applications. 3 Increased fuel consumption over extended periods. 4 Catalytic converter damage over extended periods. 5 In extreme cases, some black smoke may be visible from the tail pipe.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
When does an oxygen sensor fail in a car?
As vehicles grow older, there comes a point when the oxygen or air/fuel ratio sensor’s heater circuit will probably fail. When that happens, the easiest fix is to install a new sensor. But when the vehicle comes back two days later with the same heater code, what then? A local shop called me in on just such a case.
