It is located on top of the engine under the throttle body, it sucks, plan on a whole day if you are a good machanic.

SOURCE: code p1131 on a 1999 mercury cougar

Lack of HO2S-11 Switch, Indicates Lean.Right bank front 02 sensor. When an HO2S sensor indicates lean at the end of a test, the system is trying to correct for an over-lean condition. The code is set when the fuel control system no longer detects switching for a calibrated amount of time.In other words the 02 sensor is indicating lean and the fuel trim has reached the programed limit trying to correct it.
There are many things that could cause this like a bad 02 sensor,a vacuum leak,a leaking or contaminated fuel injector/s,a stuck open PCV valve,leak in hose between MAF sensor and engine causing un-metered or unmeasured air entering the engine,exhaust leak,improperly seated oil dipstick,stuck EGR valve.
Check PCV valve first if it is stuck open if you pull the hose off of the valve cover that hooks to the air tube between MAF and engine you will feel a strong vacuum pull there,normal you would hardly feel it.

SOURCE: trouble code 401

P0401 is: Exhaust Gas Recirculation Flow Insufficient Detected

The pipes are supposed to have pressure in them when the EGR valve is open, but sometimes, with the EGR closed may have vacuum... the DPFE compares the pressure/vacuum values from the 2 pipes (these 2 pipes take their pressure before and after an orifice) and knows how much recirculated exhaust gases go through the engine...

Your problem definitely sounds like an EGR problem, but it could be the EGR valve, the DPFE sensor, a clogged hose, a leak/clog somewhere in the EGR piping...

The code basically means your engine either is not getting the amount of burned exhaust gases it should back in the intake to lower NOx emissions or the DPFE sensor thinks your engine is not getting enough burned exhaust gases...

SOURCE: P0401 code Mercury Cougar 2000. DPFE sensor?

Yes it will. Clean out all the ports for the EGR valve check PCV valve if equipped. Vacuum lines can cause this problem also

Check engine light came on


Generally this happens because these codes were reset at a dealership etc. These problems should have been corrected before the codes were reset (reputable dealer). A common reason that these codes come on is because of excess hydrocarbon emmissions with a misfire. If this was a temporary event, the light would reset. Since it continues, another likely reason is the oxygen sensor in the exhaust system has failed.

My 1999 cougar will start but will not idle


The engine and the automatic transmission in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems.

Service engine code P0402 for Ford Mustang


P0402 OBD-II Trouble Code - Exhaust Gas Recirculation Flow (EGR) Excessive Detected

What does that mean?
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor (DPF). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0402 code means that OBD detected an excessive amount of EGR.

Symptoms
You may notice drivability problems such as the engine may surge off idle. There may also be other symptoms.

Causes
A code P0402 most likely means one or more of the following has happened:
* The DPFE (differential pressure) sensor is faulty and needs to be replaced
* There is a blockage in the EGR (most likely carbon buildup)
* The EGR valve is faulty
* The EGR valve may not be opening due to a lack of vaccuum

Possible Solutions
With a P0402, it is common for people to replace the EGR valve, only to have the problem return. The most likely solution is to replace the DPFE sensor.
* Check the voltage at the DPFE sensor both at idle and when the EGR is open
* Replace the DPFE sensor

Hope helps (remember rated and comment this).

P1401 still after replacing EGR pressure and EGR valve


Yes that is what is wrong the intake manifold is plugged with carbon restricting EGR flow you need to clean out the ports to correct the problem if you run the car to long you will burn the DPFE ( the EGR pressure sensor ) out agian

P0401 code Mercury Cougar 2000. DPFE sensor?


  1. Have tried cleaning out the throttle body? Carb cleaner and a rag should do the trick. Also, try bypassing the vacuum solenoid. First, remove the vacuum line from the solenoid, start the car, and then connect the vacuum line directly to the EGR valve. The car should run very rough and die. If not, then there is still something blocking the system (since you replaced everything, it might be down in the pipe (between valve and exhaust)). Also, ensure that the vacuum is strong enough by ensuring that the lines sticks to your fingers. Final possibility is that your new sensor is bad. You can do a voltage check (with igntion turned toon: 1 wire at 5 volts, 1 wire at 0 volts and 1 wire at about .5 tp 1.1 volts). The aftermarket sensors are not always of the best quality.

Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..
