Code says bad egr valve replaced still throws code


V6? 4cyl? what is the code? there is no code that says "replace egr valve", the passages may be stopped up. open the egr valve manually (a scanner may be able to do thiis) and see if the engine idles rough or stalls out (it should if passages are flowing) if not you need to take valve off and clean the EGR passages. If you cant open the valve, take it off, one hole is exhaust. the other will be vaccuum, from the intake manifold. A bad map sensor could also cause a egr malfunction code.

Need to find and replace the DPFE-15 sensor. Dealership diagnosed when service engine light came on and saaid this is what needed replacing. Problem is I do not know where to find it on the engine.


Exhaust Gas Recirculation (EGR) System The exhaust gas recirculation (EGR) system is designed to:
  • reintroduce exhaust gas into the combustion cycle.
  • lower combustion temperatures.
  • reduce the formation of oxides or nitrogen (NOX).
The amount of exhaust gas reintroduced and the timing of the cycle varies by calibration. Timing and volume are controlled by the following:
  • engine rpm
  • engine vacuum
  • exhaust system back pressure
  • engine coolant temperature
  • air charge temperature
  • throttle position
The EGR valve (EGR valve) (9D475) is vacuum-actuated. The vacuum hose routing diagram is shown on the Vehicle Emission Control Information (VECI) decal. The EGR system is a differential pressure feedback EGR Sensor system. Differential pressure feedback EGR Sensor is a subsonic closed loop EGR system. The differential pressure feedback EGR system:
  • monitors EGR flow rate by the pressure drop across the metering orifice located in the EGR tube.
  • uses a differential pressure feedback EGR sensor as the feedback device.
  • uses the EGR valve only as a pressure regulator, rather than a flow metering device.
  • controlled pressure is varied by the valve movement using vacuum output of the EGR vacuum regulator solenoid (9J459).
  • allows for a more accurate assessment of EGR flow requirements.

Differential Pressure Feedback EGR Sensor Removal
  1. Disconnect engine control sensor wiring (12A581) from Differential Pressure Feedback EGR Sensor.
  1. Disconnect Differential Pressure Feedback EGR Sensor hoses from EGR valve to exhaust manifold tube (9D477).
  1. Remove retaining nuts or bolts (depending upon application) and EGR Differential Pressure Feedback transducer.
Installation
  1. Follow removal procedure in reverse order.
  1. Tighten retaining nuts or bolts (depending upon application) to 5-7 Nm (45-61 lb-in).

Failed emissions got p0301,p0402 please help


V6 or 4cyl????
P0301- #1 cylinder misfire -Old/Fouled Plugs -Faulty spark plug wires/distributor or rotor (4cylinder only) -Faulty cam/crank sensor (v6 only) -Faulty #1 ignition coil or coil electrical connector (V6 only) -#1 Compression loss
P0402- EGR Issue 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 vacuum

Need to find out were the dpfe sensor is on my 1999 toyota camery with a v6 it has a code po402 and they say to check this sensor first


p0402 is egr valve flow excessive. egr valve needs cleaned or replaced also check wires etc. to vavle.

Either code 4000 or 1400 on 2002 ford ranger 4.0 ltr v6. the right code should equate to the egr valve. I have replaced the egr valve but check engine light comes on again after reset showing same code.


code p1400 is a DPF EGR sensor CIRCUIT LOW VOLTAGE detected. most likely is a problem with the wiring to the egr or dpfe sensor. the pinpoint tests for code p1400 instruct you to test all wiring before replaceing the egr or dpfe sensor

I have a 2004 lincon ls v6 and I got the code p0401 I replaced the egr valve completely and the code still came back on, what do I do? Please help.... clueless.


P0401 is a low egr flow code. It is rarely the EGR valve and more often than not the DPFE sensor that has failed. To find the DPFE sensor follow the metal tube from the EGR valve to the exhaust pipe. There will be two rubber hoses attached to that tube. The DPFE sensor will be on the other end of those hoses.

Make sure there are no holes in the rubber hoses. This can cause false codes as well.

V6 5vzfe Tacoma's does not have EGR valves. All the controlling is compensated by the o2 sensors; therefore, the o2 needs to be replaced at 100K to avoid a bad CAT converter.
