How to troubleshoot ford focus 1.8 2007 with diagnostic code P2195 and P1131?
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.

po301 thru po306 all misfire codes cylinder 1-6 remove plugs and replace them..... set the plug gap first
i suggest u replace the wires also if they never been replaced all these misfire codes can set the others and one is for the oxygen sensor ( 02s or HO2S) CIRCUT MALFUNCTION do u know how to check wireing systems
do the tune up plugs (set gap) .052-.056 change the fuel filter also. clear the codes hows it run
this info is for 98 E-250 4.2Litre
what engine do u have 4.2L or 4.6L i know it is a v-6 by the codes

Code p1131 manufacturer control fuel air metering, on a 2003 Ford Taurus. Where is part? Is there an easy way to see if it can be fixed without buying the expensive part?

Hello,
Very common concern with the Explorer, Explorer Sport Trac and Ranger with the 4.0l SOHC engine! The upper and lower intake manifold gaskets fail, causing vacuum leaks..It can be Extremely difficult to detect these leaks, because they only leak intermittently (usually in the AM after a cold soak)... As the engine warms up they seal back up! Sometimes the vehicle will idle rough, surge or stall after initial start up, then the symptoms will clear after it gets to operating temperature... Usually there will be no driveability symptoms at all, except the engine light coming on and setting lean codes.. The gaskets have been redesigned to correct this concern..

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.
