What could cause a P1151 code?
What Is a Ford Trouble Code P1151? This trouble code is signaled by your heated exhaust oxygen sensor, or HO2S. This sensor is used to test the amount of oxygen to ensure an accurate air/fuel ratio. A failed test means there isn’t enough air mixing with your fuel.
What’s an O2 sensor in a car?
The O2 sensor checks the amount of oxygen in the exhaust, compared to the amount in the air. It feeds that information to the engine computer, which then adjusts fuel and air intake. Like most auto parts, the O2 sensor has a life span. Depending on the kind of sensor, it is typically from 30,000 miles to 100,000 miles.
How do I fix the code P0171 on my Ford?

- Replace the fuel pump or fuel filter.
- Change the fuel pressure regulator.
- Replace the powertrain control module.
- Change one or more injectors.
- Replace one or more oxygen sensors.
- Change the mass airflow sensor.

What does lack of ho2s21 switch?
There are a variety of possible causes for this error code. You may see this code due to an issue with a lean in the engine vacuum, fuel injector, or fuel pressure regulator, a fuel pressure that’s too low, and defective sensors, including the O2 sensor bank 2 or the mass airflow (MAF) sensor.
Can I drive with a faulty oxygen 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.
How can I tell which O2 sensor is bad?
Signs That Your Oxygen Sensor Is Bad
- A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor.

What causes bank 1 system too lean?
A Code P0171 or system too lean bank 1 means either too much oxygen or too little fuel in the exhaust. This is a ‘lean’ condition or a ‘low fuel trim’ code. The P0171 OBD-II code indicates that the fuel system on the first bank of the engine is weak or that a vacuum leak exists near this side of the engine.
What is Bank 1 too lean?
The OBDII trouble code P0171 – System Too Lean (Bank 1) means that the engine air-fuel mixture is too lean, or there is too much air and too little fuel. Driving a car with the code P0171 can cause more damage to the engine over time, as when the engine runs lean, the combustion temperature is higher.
Can a bad O2 sensor cause a P0420 code?
Can a bad O2 sensor cause a P0420 code? Yes. A typical catalyst monitor uses the signal from the downstream oxygen sensor to determine catalyst efficiency, and the signal from the upstream sensor is a reference point. As such, failure of either the upstream or downstream oxygen sensor can cause code P0420 to set.
Will catalytic converter cleaner fix P0420?
How to Fix P0420 Engine Code with Catalytic Converter Cleaner
What is ho2s21 switch?
The P1151 code is only applicable to Ford vehicles. It indicates that there’s a problem with one of your oxygen sensors, which is what the name’s description indicates. HO2S indicates your heated exhaust oxygen sensor, and 21 indicates a problem with bank 2, in that the sensor indicates your oxygen is running lean.
What is a HO2S?
Modern vehicles use a heated oxygen sensor (HO2S) with a heating element that quickly brings the sensor up to operating temperature. The downstream sensor is primarily used for post-catalyst monitoring and checks the oxygen content of the exhaust gas that exits the catalytic converter.
What are the symptoms of a failing oxygen sensor?
Signs a Vehicle has a Bad O2 Sensor
- Check Engine Light Comes On.
- Noticeable Loss of Fuel Efficiency.
- Sulfur or ‘Rotten Egg’ smell from Exhaust.
- Black smoke from exhaust.
- Emission levels reach high levels.
- Your engine hesitates, skips, begins bucking or has power surges.
How do I know if my O2 sensor is bad or catalytic converter?
The check engine light often appears if your catalytic converter is clogged, although since the O2 sensor reports slower (because it measures efficiency over a longer period of time than other sensors), you might get a “check engine” light for something else like engine misfires, before you get a check engine light for …

How do I know if I have a bad O2 sensor or catalytic converter?
Can I clean my catalytic converter without removing it?
Things to consider before starting
There are some things that you have to consider before trying to clean your catalytic converter. In a lot of cases, the parts inside the catalytic converter will become loose. If this is the case, you can’t repair your catalytic converter without removing and replacing it.
Is HO2S the same as O2 sensor?
The Oxygen(O2) Sensor is installed in the exhaust system to determine the amount of oxygen left in the exhaust stream after combustion. This is used by the ECU to determine if more or less fuel (longer or shorter injector duration) is need to achieve optimum air/fuel ratios.
Will a oxygen sensor stop a car from running?
The only problem will be that your vehicle will run sluggishly or roughly, or it will stall. The default, limp-home fuel setting of an engine computer unit that receives no signal from the O2 sensor is an overly rich mixture.
What does a car do when the oxygen sensor is bad?
If your vehicle has a bad oxygen sensor, it could run irregularly or sound rough when it idles. A faulty oxygen sensor can impact your engine’s timing, combustion intervals, and other essential functions. You could also notice stalling or slow acceleration.
What does P1151 code mean?
What does code po131 mean?
P0131 is telling us there is a fault in the oxygen sensor, located in the bank 1 sensor 1 location of the vehicle. This is also called air/fuel sensor, or heated O2 sensor. This means that the ECU has detected either improper voltage from the oxygen sensor or improper air-fuel ratio.

Are bank 1 and bank 2 sensors the same?
Q: Are bank 1 and bank 2 sensors the same? Bank 1 and bank 2 have similar sensors. However, bank 1 has two sensors, of which sensor 1 is located near the engine before the catalytic converter, an upstream sensor called pre CAT, and sensor 2 is located after the catalytic converter called post CAT, a downstream sensor.
Is there a fuse that controls the O2 sensor?
yes, there is a fuse for the o2 heaters. check all the fuses. it may also be a harness issue and needs to be checked as well.

How to test an Oxygen Sensor with a Clamp-meter
- Make sure the engine exhaust system is cold.
- Switch the clamp-meter on, to ‘DC current/DC amperage’ mode.
- Put the clamp around either of the oxygen sensor heater power wires (but not both).
- Turn the engine on.
- Observe the reading, which should be between 0.25A and 1.5A.
What kills an oxygen sensor?
MALFUNCTIONING AND FAILED SENSORS Oxygen sensors can fail when the sensor’s ceramic element is exposed to certain types of silicone compounds or when an oil-burning engine leads to the sensor becoming oil-fouled. Also, a small amount of tetra-ethyl lead in the gasoline can kill an oxygen sensor.
What sensor controls the EGR valve?
The EGR fraction is controlled by the EGR valve and intake manifold pressure is controlled with the VGT. Critical sensors are an exhaust manifold pressure sensor (P2), an intake manifold pressure sensor (P2) and a speed density estimate of total mass flow.
