SOURCE: computer error codes

this is your O2 sensor and is located after the air filter so check your air filter it may need to be replaced it is not getting the correct amount of air
the other code it is private for the ford dealer only but it may go out once you fix the air sensor

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.

SOURCE: 2002 Ford Windstar Error Code P1131 And P1151

those two codes are for the o2 sensors. both are the upstream sensors on the front and rear banks. so they are desinagted bank 1 sensor 1 and bank 2 sensor 1. them most common cause for this is faulty o2sensors , bad gas and of a poor running engine. so if your car runs good (no misfire) and gas is ok then replace the o2sensor witch is the very most common cause.

If you bought an after market EGR, they normally have different size orifices with them. If the correct diameter isn't used, it can give you the same error. The H02S11 refers to the first Heated Oxygen Sensor on bank 1. It can be caused by a leaky vaccuum line at the Mass Air Flow sensor or a bad PCV valve or PCV system hose.
Occasionally it will indicate a plugged fuel injector or low fuel pressure.

P1130,p1131,p1132,p0402


p 0402 is EGR valve and solenoid problems
that sort of back pressure indicates cat converter is blocking the exhaust system
the rest are o2 and Ho2 sensor problems probably from the faulty cat
one side would be oxygen sensor trying to adjust mixture but unable from cat
fix the cat converter/s and then get a fault code reading
next post include make , model and year and engine type

Gives a error code P0113 and does not start. It cranks but does not start?


you need to replace a sensor
Intake Air Temperature could also mean the Maf needs a clean

error code explained
The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor

Error code P1131 & P1151


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

Grand carvan gives p402 code


This is not a cut and dry fault code. This means that more than one thing wrong can set the code in the computers memory. Here is the low down on the P0402 fault code. This is from the OBD2 fault code diagnostic book.

P0402 - Exhaust Gas Recirculation Flow Excessive Detected
Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Possible engine hesitation
Possible causes - EGR solenoid valve harness is open or shorted
- EGR solenoid valve circuit poor electrical connection
- EGR volume control valve stuck closed
- Dead (Weak) battery
- Faulty EGR temperature sensor and circuit
- Faulty EGR Valve
- EGR passage clogged
- Exhaust gas leaks

All of that going on all at the same time is not likely at all. Are you sure the engine is actually overheating or is that just what your instrument panel is telling you?
With all of those things going on at the same time, here is what I would do. First I would take a REAL HARD look at the charging system. Goofy stuff like this is often caused by a battery with a shorted cell or an alternator with bad diodes that is feeding AC current into the computer network. The computers tend to do really goofy things when they are suffering from malnutrition.

Once I am satisfied that the charging system is in good condition, then I would clear the codes and go on a road test. If the check engine light comes back on, I would immediately scan the engine controller to find out which of the codes came back and fix it FIRST. Many times, fixing one code can fix ALL the codes. By doing it this way, you are more likely to find which one is your MAIN problem.

If your engine is actually overheating, all I can say is you need to diagnose your engine cooling system to find out why...all of the misfire codes could very likely be a result of the engine overheating and fixing the engine cooling system will most likely fix these codes.
