What is trouble code po133?
The code P0133 indicates your vehicle’s oxygen sensor is having a problem. The oxygen sensor essentially works by transmitting a voltage reading to the computer. This reading changes every time the air-fuel ratio changes, which in turn changes every time the driver presses the pedal.
What causes a P0133 code?
Code P0133 is triggered when the voltage output that your O2 sensor is meant to send to your ECM does not change quick enough in relation to the air to fuel ratio when you press on the gas pedal.
How do I fix po133 code?
What repairs can fix the P0133 code?
- Usually a replacement of the oxygen sensor will fix the P0133 code.
- At times the sensor itself will not be causing the code P0133, so a technician must check for other faults such as vacuum leaks, a dirty mass air flow sensor, or leaks in the exhaust system.
What does O2 sensor delayed response mean?
OBD Code P013E – O2 Sensor Delayed Response – Rich to Lean (Bank 1 Sensor 2) <Engine Control Module (ECM) has detected a problem with the amount of resistance in the heater circuit for the oxygen sensor on bank one of the engines.
Is there a fuse for 02 sensor?
There are no fuses for the O2 sensors. They are controlled by the PCM.
What does p0133 stand for in diagnostic code?
Diagnostic Trouble Code (DTC) P0133 stands for “Oxygen Sensor Circuit Slow Response (Bank 1, Sensor 2).” It is triggered when the downstream oxygen sensor (located after the catalytic converter) in Bank 1 takes too long to transmit signals to the PCM.
What causes an O2 sensor to set p0133?
Not cleaning the wires and electrical terminals of the O2 sensor Overlooking the fact that a leaking vacuum line or intake manifold leak may cause erratic O2 sensor voltage readings. Voltage readings which may set a code P0133
How much does it cost to repair a car p0133?
The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0133 code detected? The response of the voltage signal from the sensor takes more than the specified time.
What to do when the freeze frame code is p0133?
When the code P0133 is set, record the freeze frame data in fine detail. Next, duplicate the code setting conditions on a test drive, paying particular attention to load, MPH, and RPM. The best tool to use on this test drive is a data streaming scan tool that has factory quality, dedicated live data.
