SOURCE: Check engine light came on.

P1135 means that your O2 sensor has gone bad. The O2 sensor on the Toyota's are called Air fuel sensor's. If you have a 4 cylinder engine, the O2 is on the exhaust down pipe before the catalytic converter, and if it's a V6 it the O2 sensor on the fire wall side along the down pipe from the exhaust manifold. (sensor 1, bank 1) Good luck and keep me posted, check the wire harness. The wire harness could have corroded or burnt from the exhaust, but most likely it's going to be a bad O2. Keep me posted ,be glad to help

SOURCE: Check engine code P1135 Toyota Highlander v-6

what you looking at on that code is an o2 sensor, the 1135 is bank 1 sensor 1, that says which o2 sensor it is, since most vehicals, especially new foreigns have more than one, this code refers to the first one in your system so if you follow your exhaust manifold back to your pipes, the first one you see, probally right on the manifold, is the one thats malfunctioning. To change it, simply disconect the plug, and use a o2 sensor socket with a ratchet to remove it, and screw the new one back in and plug it in. Pretty simple, wish you luck.....

It is you air fuel sensor on the exhaust manifold. It most likely requires replacement.

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.

What does code p1131 mean on a 2001 ford taurus


P1131 Ford
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.
  • Check intake air system for leaks, obstructions and damage.
  • Check air cleaner element, air cleaner housing for blockage.
  • Verify integrity of the PCV system.
  • Check for vacuum leaks.

P0401. P0133, P1131- emmision test


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.
