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

SOURCE: I have a 98 f-150 5.4 triton showing coads

I would start with the Rubber elbow on the back of the intake, next to the IAC.

This has a habit of cracking, and causing unmetered air after the MAFS to get into the system. The closed loop control is not counting it, and the O2 sensors are reporting the lean condition on the back side.

Ignore the IAC notation in this picture ( only 1 I had ) You are going to want to remove the plastic cover on the throttle body, and take a look at the rubber vac line that is shown in this picture.

The other item could be the intake manifold is loose, but start with the vac lines, clear the code with a scanner, a battery disconnect for 5 min, or 2 driver cycles to see if at least the P0170 & P0174 codes are gone.
The P0136 & P0156 could be a melted wire as mcneb posted about, this is usually by the exhaust manifold. After checking and repairing the vac lines ( if required ) follow the harness from the 2nd set of O2 sensor ( think that is HO2S-12 & -22 if I recall correctly ) to the engine compartment.

SOURCE: P0136, P1131, and P1151 codes on Ford Expedition 2000 4.6L

Your auto has four O2 sensors. Two upstream and two downstream; With two banks. Bank 1, sensor 1...and bank 2, sensor 1 are the two upstream (exhaust manifold before the catalytic). Bank 1, sensor 2 and bank 2, sensor 2 (other side of catalytic)

Code 1131= upstream; bank 1..sensor 1
Code 1151= upstream; bank 2..sensor 1
Code P0136 (generic code) bank 1..sensor 2 (questionable)

I wouldn't spend the money to purchase 3 sensors. Highly unlikely all three are bad; Cost is about $40/ ea.
Since there isn't a code for the cat's themselves, I would suspect the O2 circuit is malfunctioning. The rough idle is another clue.


Take an ohmmeter set it on X10 scale and measure the resistance from engine to body and body to negative post on battery terminal. You should read zero ohms (full needle deflection). If you do go buy two upstream O2 sensors. If you read
open or a high resistance run two straps from eng. to body...and body to neg.batt. post.

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.

Code 1150 on a 1997 ford f 150 with a 4.2 motor


I will try to paste an article for you. Several sources indicate this is a Bank 2 O2 sensor problem and that it is failing to switch and adjust for the fuel mix. But as you can see, many defects can lead up to this O2 sensor Code 1150.

I would try to use a spray bottle of water and go around the Intake manifold and spray the water while the engine is running. An intake leak will draw water into the engine and change RPM.

If no success then try changing the O2 bank 2 sensor. You may need to wipe the computer and clear the Code. H40 DTCs P1131, P1132, P1151 AND P1152: UPSTREAM HO2S NOT SWITCHING. DTC P1130: FUEL SYSTEMicon1.png NOT SWITCHING AT FUELicon1.png 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.

Trouble codes p1131, p1151 and p0171 for 2001 expedition


I don't care how handy you are , that's not going to help you unless you have knowledge of OBD 2 engine management system for your vehicle . Plus having diagnostic test equipment , scan tool to view engine sensor data ., an knowing how to do automotive electrical circuit testing.
Po171 Could be just an O2 sensor problem ,looking at scan data for bank 1 sensor 1 for proper switching , could be a easy find for a trained Tech . You on the other hand could spend hundreds an still not fix the problem .

P0171 - System to Lean (Bank 1) The Adaptive Fuel Strategy continuously monitors fuel delivery hardware. The test fails when the adaptive fuel tables reach a rich calibrated limit. For lean and rich DTCs:
  • Fuel system
  • Excessive fuel pressure.
  • Leaking/contaminated fuel injectors.
  • Leaking fuel pressure regulator.
  • Low fuel pressure or running out of fuel.
  • Vapor recovery system.
  • Induction system:
    • Air leaks after the MAF.
    • Vacuum Leaks.
    • PCV system.
    • Improperly seated engine oil dipstick.
  • EGR system:
    • Leaking gasket.
    • Stuck EGR valve.
    • Leaking diaphragm or EVR.
  • Base Engine:
    • Oil overfill.
    • Cam timing.
    • Cylinder compression.
    • Exhaust leaks before or near the HO2Ss.

P1130 - Lack of HO2S-11 Switch, Fuel Trim at Limit The HEGO Sensor is monitored for switching. The test fails when the HO2S fails to switch due to circuit or fuel at or exceeding a calibrated limit.
  • Electrical:
    • Short to VPWR in harness or HO2S
    • Water in harness connector
    • Open/Shorted HO2S circuit
    • Corrosion or poor mating terminals and wiring
    • Damaged HO2S
    • Damaged PCM
  • Fuel System:
    • Excessive fuel pressure
    • Leaking/contaminated fuel injectors
    • Leaking fuel pressure regulator
    • Low fuel pressure or running out of fuel
    • Vapor recovery system
  • Induction System:
    • Air leaks after the MAF
    • Vacuum Leaks
    • PCV system
    • Improperly seated engine oil dipstick

    • Leaking diaphragm or EVR
  • Base Engine:
    • Oil overfill
    • Cam timing
    • Cylinder compression
    • Exhaust leaks before or near the HO2S(s)
A fuel control HO2S PID switching across 0.45 volt from 0.2 to 0.9 volt indicates a normal switching HO2S. P1131 - Lack of HO2S-11 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130
P1151 - Lack of HO2S-21 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130 006 O2 Sensor Signal Analysis

What is the p1131 and the p1151 codes mean?


P1131 and P1151 are for the oxygen sensors. one in the exhaust at the firewall and one at the radiator off the manifold. When both go off though at the same time I would suspect a vacuum leak after the MAF sensor(mass air flow), if only one code then suspect that O2 oxygen sensor

Idling rough in cold weather codes that come up are p1131 and p1151 need to know what these codes are and what parts they are


DTC P1131 DTC P1151 indicates the system is correcting RICH for an overly LEAN condition. The Heated Oxygen Sensor (HO2S) voltage is less than 0.45 volts. This is usually due to a vacuum leak after the MAF. It can also be caused by a bad PCV valve or PCV system hose. It can also be caused by low fuel pressure or a plugged injector.

Start with the simple and clean the MAF and the IAT sensor. In simple terms, the engine is running lean and is being compensated by the ECM. P1131 is bank 1 and P1151 is bank2

Good luck and keep me posted.

Have engine trouble codes P1151 and P1131


If both, P1131 and P1151 trouble codes are set at the same time, the problem will most likely be attributed to a vacuum leak past the MAF (Mass Air Flow) sensor or something else that would likely affect BOTH banks. If the problem is only causing one code or the other, but NOT both, the problem will most likely be something that would affect one bank, like a bad O-2 sensor or a fuel injector; the most common cause of a single code either the P1131 or P1151 in my experience has been a bad Oxygen sensor.
