I was reading in one of my repair manuals and it says in there that there could be a block where the exhaust gas pressure sensor is. There could be a blocked inlet hose. Or it could be the ECM.

P0174 p0402 p1150 p1151 and p0401


Hi there:



P0401 OBD-II Trouble Code - Insufficient EGR Flow
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 EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.


Symptoms: You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms.


A code P0401 most likely means one or more of the following has happened:
The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
There is a blockage in the EGR (tube), most likely carbon buildup
The EGR valve is faulty
The EGR valve may not be opening due to a lack of vaccuum


Possible Solutions: in fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.


Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
Clean out the EGR valve and/or tubing to remove deposits
Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
Replace the DPFE sensor (with a good quality / OEM one)
Replace the EGR valve




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


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

P1150 OBD-II Trouble Code - Air/Fuel Sensor Circuit Range/Performance (Bank 1 Sensor 2)


P1151 OBD-II Trouble Code - Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2
upstream is considered the oxygen sensor for the right side exhaust manifold, before the catalytic convertor. Make sure the sensor's electrical connection is in good condition. On the sensor, test between the terminals with an multimeter/ohmmeter. You should see about 6 ohms at 68*F. If not, replace.

The reason your engine is doing that is because the sensor is failing in such a way that the computer is dumping in extra fuel when it isn't really needed. Then you get the black smoke.





Hope this helps.

2005 Ford F150 Engine check light blinking on & off?


Any symptoms,Dawn, such as performance troubles? Might be an oxygen sensor going bad, catalytic converter starting to plug, or EGR valve getting dirty and sticking.
If you can,get the OBD II codes run. They should help pinpoint the problem.My guess is it's an oxygen sensor,but that's only a guess. don-ohio (:^)

My engine light is on so i took an OBD reading and it showed the error codes P0401, P0420 and P0133. What do I need to fix?


P0401 is EGR valve, low circulation detected.
P0420 Catalyst system.
P0133 is O2 sensor bank 1 sensor 1.
All these codes are emissions related, so i would start with the EGR valve, it's probably clogged with carbon. The catalytic converter could be also, check that for excessive backpressure. The oxygen sensor can be tested, replace if needed. Good luck, i hope this helps.

Have a 1995 ford contour and took it to pepboys and they got multiple codes. One of the codes came up twice code 332 says egr valve not opening could this cause all the other codes? My husband has checked...


DTC P0332 is for a knock sensor, not egr valve. That's not to say one of the multiple codes you've mentioned wasn't for the egr valve.

What are some of the characteristics the vehicle is showing. By the way, what is the vehicle? In one place it says 1995 contour, in another it says 1995 explorer.

Where is the EGR sensor located on a 1998 ford contour se


It's a valve not a sensor.
Where? it depends what engine do you have 4 cyl 6 cyl?
How do you know the EGR valve could be bad? check engine light on? OBD code? diagnostic made?
Help us to help you please provide more information
Hope it will help
