SOURCE: check engine light code is p1131 fuel air metering

Check the vacuum hoses under the hood for a leak. The elbow on the PCV hose commonly develops a hole. You may be able to hear a hissing leak. Replacement works better than any patch.

If you can't find any hose leaks, the mass air flow baro sensor may be damaged. It's in the air cleaner box. Cleaning the wires (degreaser or brake fluid) on the sensor may help.

If cleaning doesn't work it may have to be replaced.

After cleaning or replacement you should disconnect the battery ground cable and reattach it after a couple of minutes to clear the light.

Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.

These codes are dealer specific. Please call you local dealer and they will give you the exact meaning.

For now I think you may find the code needs to be verified.
Here is my advice.
Have the reading done by - Auto Zone and also Advance Auto all over again. If the codes match
Take down the vin# - call the dealer and tell them the code. Ask them what it means and - -ask if your vin# brings up and recalls or service needs as issued by the factory. Some things never go out of date.

One last this - your header here says 1995 -your note says 1998. You need to sort that out as well.

What do code p1131 mean on a Lincoln Continental 2002


Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 1
In simple terms, it means the engine computer is not "seeing" the O2 sensor switch from rich to lean like it should be doing.
When the O2 sensor switches to lean the computer makes the injectors open more to let in more fuel, until the sensor switches to rich.

P1131 Ford - Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 1

Repair Importance Level: 3/3

Repair Difficulty Level: 2/3

http://engine-codes.com/p1131_ford.html

Forum Code

Possible causes

- Faulty Oxygen Sensor

- Vacuum leak affecting bank 1 only

- Fuel injector problem bank 1

- Check for cylinder misfire on bank 1

- Engine mechanical condition

Tech notes

Though the Oxygen (O2) sensor, the Engine Control Module (ECM) has detected a lean system, which means that there is either not enough fuel or and excessive amount of air in the system. Start by checking for vacuum leaks.

When is the code detected?

The Engine Control Module (ECM) detected bank 1 oxygen (O2) at its lean limit

Possible symptoms

- Engine Light ON (or Service Engine Soon Warning Light)

P1131 Ford Description

A Heated Exhaust Oxygen (HO2S) sensor indicating rich at the end of a test is trying to correct for an over-lean condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

P1131


Check Engine lights are the worst. The OBD2 code P1131 suggests a problem with the fuel air mixtures. Often though, the check engine alerts result from failing or faulty sensors rather than from what the sensor is suggesting. It is advisable to check the sensor first.
Good luck!

I have a 1998 ford contour that has codes p1130 and p1131 on it what could be the problem. the check engine light is on


H40 DTCs P1131, P1132, P1151 AND P1152: UPSTREAM HO2S NOT SWITCHING. DTC P1130: FUEL SYSTEM NOT SWITCHING AT FUEL TRIM (RICH OR LEAN)
    Diagnostic Trouble Codes (DTCs) P1131 bank 1 (Cylinder 1) and P1151 bank 2 indicate the fuel/air ratio is correcting rich for an overly lean condition. The HO2S voltage is less than 0.45 volt. DTCs P1132 bank 1 (Cylinder 1) and P1152 bank 2 indicate the fuel/air ratio is correcting lean for an overly rich condition. The HO2S voltage is greater than 0.45 volt.
    DTC P1130 and P1150 indicate the fuel control system has reached maximum compensation for a lean or rich condition and the HO2S is not switching.
    DTC/HO2S Reference List
    • HO2S-11 = DTCs P1131, P1132 and P1130
    • HO2S-21 = DTCs P1151, P1152 and P1150
    Possible causes:
    Fuel system
    • Excessive fuel pressure.
    • Leaking fuel injector(s).
    • Leaking fuel pressure regulator.
    • Low fuel pressure or running out of fuel.
    • Contaminated fuel injector(s)
    • Vapor recovery system
    Induction system
    • Air leaks after the MAF.
    • Vacuum leaks (vacuum lines and gaskets).
    • Restricted air inlet.
    • PCV system.
    • Improperly seated engine oil dipstick.
    EGR System
    • Leaking gasket.
    • Stuck open EGR valve.
    • Leaking diaphragm.
    Base engine
    • Oil overfill.
    • Cam timing.
    • Cylinder compression.
    • Exhaust leaks before or near the HO2Ss.
