Hope this helps you or future parties of intrest. P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1 P1151 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2 I would get under your stang and gently clean outside portion of o2 sensors using a scotch brite. Also if you have so dielectric grease pull electrical connections to o2 sensors clean them and add grease. These trick eliminated the o2 sensor OBD1 codes on my 1987 Ford mustang gt

SOURCE: 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.

ISSUE:
Some 2001-2003 F-150, 2004 F-150 Heritage and 2001-2003 E-150/250 vehicles equipped with a 4.2L engine may exhibit the malfunction indicator lamp (MIL) on with diagnostic trouble codes (DTCs) P1131 and/or P1151 (system too lean bank 1 or 2). This condition may be due to leaking isolator bolts/port gaskets in the upper-to-lower intake manifold mounting area. This condition is sometimes intermittent and may not be apparent on a warmed-up engine.


SERVICE PROCEDURE

Perform a self test. If DTC P1131 and/or P1151 are the only codes stored in the powertrain control module (PCM) proceed to Step 2. If any additional DTCs are present, follow normal diagnostic procedures found in the PC/ED Manual.

Remove the upper intake and replace only the port gaskets (9H486) and isolator bolt assemblies (9S479). The new isolator bolt assemblies use a rubber material that is green in color, do not install the old isolator bolt assemblies with the black rubber material. Do not replace any other intake parts or gaskets.
While the upper intake manifold is removed, check the exhaust gas recirculation (EGR) orifices that are pressed into each primary port of the lower intake manifold. If any of the orifices are plugged with soot, clean and unplug them with a pick and solvent.

2002 Ford Mustang GT. I was driving and it made a bang noise and now I hear exhaust or air. check engine light is flashing codes P1131, P0303 and P1151. has anyone else had this problem


Did it blow the spark plug out of cylinder 3 ?
Code 303 is for a loss of power from cylinder 3, code 1131 is for a problem with the O2 sensor in bank one and code 1151 is for the same problem in bank two. Codes 1131 and 1151 could be caused by the problem source for code 303.

Diagnostic code p2195 and p1131 for ford focus 2007?


P1131-- Lack of HO2S-11 Switch ,Sensor Indicates lean

P2195-Lack of HO2S-11 Switch,Sensor Indicates Lean


If you have one or two front upstream sensors & have 100,000 miles
on them, replace them as preventative maintenance

The codes are for an Oxygen Sensor closest to the engine,
on the side #1 Cylinder is on

Sensor Codes could be caused buy a leaking injector,
low fuel pressure,running out of fuel,EGR problem,Exhaust
leaks before sensor or converter,any vacuum leak,& other issues

Remove the spark plugs to see if they are fouled from fuel

You can not fix an injector with any fuel tank additive
They have to be removed & mailed away to be cleaned
if they stick open,you could install one if it leaks & is the
only issue.

I have a 98 mustang 3,8 and i just got a P1131 code how do i fix this? does this need my immediate attention?


Code is "lack of heated O2 sensor switch, sensor indicates lean" The bank 1 O2 sensor needs replacing. You will burn a bit more fuel while the engine is warming up. The only problem is that with the light on you may get another code and not realize it.
