EGR SYSTEM PROBLEM ON 1999 EXPLORER

I HAVE A 1999 FORD EXPLOROR WITH A 5.0 LITER V8. THE ECM SET A TROUBLE CODE OF P0402(EGR SYSTEM PROBLEM). IT STATED THE PROBABLE CAUSE WAS THE EGR VALVE OR OR EGR PRESSURE SENSOR OR POSITION SENSOR. I KNOW WHERE THE EGR IS BUT CANT LOCATE THE OTHER TWO SENSORS. IS THERE A DIAGRAM SHOWING THEIR LOCATION OR CAN YOU TELL WHERE THEY ARE. I INEND TO REPLACE THEM ALL AS I DONT HAVE THE CAPABILITY TO TEST THE PARTS.

96 ford explorer failed emissions test with codes p0401,p0402,p0755,p0756


P0401
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.

P0402
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.

There sound like a bad EGR and need replace it.

P0755 Shift Solenoid B Malfunction and P0756 Shift Solenoid B Performance or Stuck Off. First I suggtes check leve fluids and preventive maintenance.

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).

I have a 1999 ford ranger and the check engine light is on. The code I received is P0402. What should I do to fix this problem?


P0402 is "EGR FLow Excessive Detected". The possible cause are a bad DPF EGR sensor, a bad EGRVR solenoid or possibly a bad PCM. The first thing to check is the wiring for breaks and be sure the connectors are clean and tight. Also check the vacuum lines for proper routing and that there are no breaks or cracks in them. I hope this helps and good luck.
