What is the P0099 fault number? What is the description of the failure of Heated Oxygen Sensor, (HO2S), Switch Displays Low/Lean Bank 2 Sensor 1? How do I fix the P0099 fault code What are the causes and symptoms of the P0099 error code?

What is the P1151 Fault code?

P1151 is only applicable to Ford vehicles, unlike many OBD fault codes. This code is activated by the heated oxygen sensor, (HO2S). This sensor can be used to determine the air/fuel ratio as well as to test for oxygen content. If you don’t get enough fuel in your vehicle, a dense mixture of fuel and air will result. The test will fail. This is when the PCM / ECU generates the fault code.

This can be caused either by improper air intake or too much fuel. It’s usually an indication of an electrical problem with your HO2S or PCM/ECU.

 

What are the symptoms for P1151 Malfunction Code?

It is unlikely that you will notice performance problems in your vehicle. You will not see any performance issues in your vehicle if the check engine lights come on.

Fault code P1151 can be ignored if there are no symptoms. This sensor may be triggered by a more serious problem in your engine, fuel system or induction system. It is important to determine the root cause and then find a solution.

 

What causes the P1151 fault code?

The P1151 fault code can occur for many reasons. It is important to inspect many interrelated components for possible reasons, such as the electrical system (induction system), PCV system, internal engines components, EGR and fuel system . The main cause of the problem can be an electrical problem with any one of these parts.

First, check your electrical system for any problems. You may have damage to your powertrain control module or HO2S. There may be water in the wiring connectors or loose wiring connectors. Check the wiring harnesses for corrosion, damage, and shorts. These will result in an incorrect reading of HO2S and a code P1151.

Next, check your fuel system. Trouble codes can be caused by fuel injector problems, low fuel, and excessive fuel pressure. You should inspect your fuel system for any damaged or contaminated components. This could lead to an imbalance in fuel and air.

Other systems could also be at fault for this fault code. This could be caused either by an air leak from your mass air flow sensor or by a leaking gasket inside your EGR. This error code may also be caused if the engine oil dipstick is not correctly placed.

An engine could have problems like cylinder compression, cam timing issues or oil overfilling. An error code P1151 will also be generated if there is an exhaust leak close to the HO2S. Each one of these causes should be examined carefully to determine the cause.

 

How to Fix the P1151 Fault Code

There are many reasons why you might need to fix the problem quickly. You may need to adjust some issues like a dirty fuel injector, or a misplaced Dipstick. More extensive repairs are required for components such as the damaged powertrain control module and leaking EGR.

After you have repaired the problem, you can delete the code and see if it’s still the issue. If the code appears again, continue looking for other causes and fixing what you find. Run your tests by deleting all the code.

Do not wait to notice performance problems. You can prevent further damage to your fuel system, EGR system or inboard engine components by looking for the problem.
