Had my 2014 Tourneo Custom serviced by local dealer .1/2 hour later EML comes on and white smoke pouring out of exhaust during DPF regen.Returned to dealer they said the EGR valve was stuck open and the Dpf was 250% clogged .Replaced Dpf ,EGR valve and Fuel vapour valve and fuel filter cost £1100. 20 miles later same problem,dealer said The valve has to be held very still for a measurement. The pot resistance is typically 5k (2k to 10k say) from end to end, with a smoothly varying resistance on the signal to either end. I have had a lot of electrical problems with the EGR on my 1.8, which is very similar. Just bad contacts inside the unit, both on the pot & the motor. Another important component is the exhaust gas recirculation (EGR) valve, which helps reduce nitrogen oxide emissions by redirecting some exhaust gases back into the intake manifold for re-combustion. However, EGR valve problems can also contribute to Ford Transit Duratorq 2.2 engine problems such as rough idling or stalling during acceleration.
Everyone was telling me that the issue was with my EGR. Sometimes leaving the fuel cap off or loose will throw the same code and check engine light. 1997 - 2003 Ford F150 - EGR Problems - HELP!!!!! I have a 1998 F150 v8 4.6l. We have changed the EGR valve, Purge valve solenoid, and the Valve Pressure Sensor.

P0403: EGR→ Circuit Malfunction. A circuit malfunction implies that there is a wiring problem coming to or from the EGR system. That does not rule out the EGR solenoid itself. We’ll go into the most common symptoms and causes of P403 directly below. As far as the average do it yourselfer being able to diagnose the cause of this code, it can

Causes of EGR not Ready. Many issues can be responsible for code P0401 to display. But, the five common causes of a malfunctioning EGR monitor or valve are: Recent Battery replacement. ECU Memory resetting. Emissions control system problem. Software Updates. Component Replacement or Repair.

Well, since the EGR cooler has been bypassed, if the workshop has done the bypass on the EGR cooler correctly, it can't be due to this. Possible would be a warped cylinder head (if the old head was used again). Also possible is a problem with the water pump or the thermostat.

Hi I have a transit custom 2016 limited spec 155 and I’m getting a fault code. P00BD - 00 Mass or volume air flow A circuit range / performance -Air flow too high. Have fitted a new sensor in air box have fitted new sensor in intercooler and problem still there I have reset values also. Can’t see any holes in intercooler pipes and when I by williamscl5 » Mon Feb 09, 2009 3:13 pm. EGR valves rarely go bad. Most of the time the EGR ports are partially blocked in the TB or from the manifold to the EGR valve. Usually, the DPFE will cause "drive-ability" probs. Check your ports! 2002 F150 5.4L XLT SuperCab LB 4X4 3.55LS. True Blue/Silver 2 Tone. 6.7 Powerstroke EGR valve can experience clogging due to fuel quality. Once debris builds up in the EGR valve, it tends to burn fuel faster. Diesel produces more debris than gasoline when burning. The most common EGR problem with Ford affects the turbocharge. However, the best cetane level should be 45 and above for 6.7 Powerstroke. The EGR valve on the 2.5D models is vacuum controlled. Simply block (disconnect from the EGR) the vacuum line and the EGR valve will be kept closed. This is the easiest way to get rid of the EGR problem. There were other easy suggestions on the forum - for example, locking the throttle in the open position. .
