What does Ford code P1151 mean?

What does Ford code P1151 mean?

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. This could be the result of improper air intake.

How many O2 sensors does a Lincoln LS have?

Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.

What is HO2S?

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.

How do you fix trouble code P0171?

What repairs can fix the P0171 code?

  1. Replacing the fuel pump.
  2. Replacing the fuel filter.
  3. Replacing the fuel pressure regulator.
  4. Replacing the powertrain control module.
  5. Replacing one or more injectors.
  6. Replacing one or more oxygen sensors.
  7. Replacing the mass air flow sensor.
  8. Repairing a vacuum leak.

Can bad fuel injectors cause P0171 code?

Clogged fuel injectors or a dirty fuel filter will cause a similar backup. In cases where the vacuum system is leak-free, there is enough gas reaching the engine, and the code P0171 still shows with your check engine light, there remains a hope of finding the cause.

Can a bad PCV valve cause P0171?

The most common causes of the P0171 code are vacuum or intake leaks, low fuel pressure, faulty PCV valve, or a faulty MAF sensor. Other things can also cause the P0171 code.

Is it OK to drive with a P0171 code?

Any time your check engine light is on, you should take the reading seriously. A P0171 code is no exception to this rule. When the engine stores this code, you should not drive your vehicle far, if at all. When your engine runs lean, there is not enough gasoline for it to run efficiently.

How much is it to fix a P0171 code?

What is the cost to resolve a P0171 code? This code will require a diagnostic check, which will run about $100 depending on the time it takes to find the issue.

What does the code P0052 mean?

Diagnostic trouble code (DTC) P0052 code stands for “HO2S Heater Circuit High Voltage (Bank 2, Sensor 1).” This code is set when the powertrain control module (PCM) detects that there is a mismatch between the desired and actual state of the control circuit of the heated oxygen sensor (HO2S) 1 on bank 2.
