What the P0133 code means. Bank 1 Sensor 1 is a sensor that is used by the computer (ECM) to monitor the amount of oxygen exiting the engine. ... P0133 indicates the ECM senses that the O2 Sensor is not changing its voltage output quickly enough to the changing air-fuel ratio.

What causes O2 sensor slow response?
The slow response of an O2 sensor may be due to a sensor that is just getting old and over time may get contaminated with time with carbon and other contaminants that deteriorate the sensor over time.
Where is bank 1 sensor 1 located?
On most in-line engines, the bank 1 sensor 1 will be located at the engine's front side, near the cylinder head. On most front-wheel-drive models with V6 engines, this sensor will be on the backside against the firewall. Most rear-wheel-drive cars and pickups will have this sensor on the passenger side.
Can you drive with a P0133 code?
Like with most O2 sensor problems, you can most likely keep driving with a P0133 code, but you'll want to get it fixed. You'll be using more fuel and won't have a chance of passing an emissions test if required in your area.
What is slow circuit response?
Diagnostic trouble code (DTC) P0139 stands for “O2 Sensor Circuit Slow Response (Bank 1, sensor 2).” It indicates that the powertrain control module (PCM) has detected a potential issue with the signal from the rear oxygen sensor on bank 1. ... But the rear sensor's signal should vary somewhat over time.
What does O2 sensor delayed response mean?
OBD Code P013E - O2 Sensor Delayed Response - Rich to Lean (Bank 1 Sensor 2) <<See All OBD Codes. When this code is set it means that the 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.
Can O2 sensor be bad without code?
Like other engine sensors, there's no need to replace an O2 sensor as long as it is working properly and accurately reading the oxygen content of the exhaust. ... Such problems may not be bad enough to set a code, but they could have a detrimental effect on engine performance, fuel economy and emissions.
Can you drive your car with a bad O2 sensor?
Can You Drive With A Bad Oxygen Sensor? Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don't leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.
Can a faulty O2 sensor cause misfires?
If an oxygen sensor or mass airflow sensor is failing, it could give incorrect data to your engine's computer, causing the misfire. When a vacuum line is broken, it can cause a fuel-injected motor to misfire.
