Loss of Power while driving/car goes into Limp Home (Ford term) mode:
(see take aways at bottom of response for complete list of parts that need to be replaced to fix P1016 error code)
After owning my 2015 Edge SEL for over 7 years (original owner) out of the blue I experienced a substantial loss of power (LoP)/Limp Home mode while highway driving w/o any warning lights on the dashboard. I pulled over to a safe location and listened to the motor for any tell tale indications of what might be wrong but the motor sounded fine. Turned it off, waited ~ 1 minute, restarted and all was well. Got back on the highway with good acceleration and drove home. Please note, this was the very first time my Edge had been anything other than perfect as far as operation and transport and assumed this was a one time “who knows” event and didn’t give it further thought.
Unfortunately, over the next 2 months it started to happen more and more frequently so I started to look around the internet to find what the cause(s) might be. Turns out quite a few other owners had experienced similar symptoms followed by unfulfilling dealership repair shop visits e.g. Technicians would say no error codes/trouble lights were found and they could not replicate the LoP during their analysis but the theories offered were many and varied e.g. spark plugs fouled, fuel lines clogged, fuel pump malfunction, catalytic converter, air filters, fuel filters, etc. At this point I was quite troubled and didn’t want to get into some endless “visits to the Dealership repair shop” w/o any success but costing hundreds of dollars for each visit.
Being all the technician stories included “lack of OBD2 error codes” being found I decided to buy one to monitor the motor real time and see if it would be helpful in discovering what was wrong. I bought the lower end version of “FIXD” OBD2 Diagnostic Trouble Code (DTC) Decoder for ~$39 and it was delivered to my house the next day. Installation was simply to plug into the receptacle jack located under driver side dashboard on cars made after 1995, down load the FIXD App and then Blue Tooth connect to my Android based cell phone.
JACKPOT. Within 1 day of driving while being monitored real time by FIXD my cell phone reported error code P1016 “Wastegate Regulating Valve had experienced overpressure to the turbo charger”. FIXD not only decoded what the code meant it also identified 3 specific parts that if malfunctioning would cause the error.
Armed with this information, I went to the local Ford Dealership with printouts of what FIXD had provided and asked them to repair. We agreed they should do a diagnosis with their more sophisticated error machine to confirm my findings and their machine gave the same findings. They installed the Wastegate Regulating Valve and the two tubes identified below. I picked car up next day and worked fine ever since.
Key Take Aways:
.Buy an OBD2 real time monitoring device to reduce stress/uncertainty and put ourselves on equal information footing with the dealership technician
.Suggest replacing all parts that the OBD2 identifies to avoid multiple visits to the shop. Parts for replacement are:
.Wastegate Regulating Valve (WRV)
.Control tube btwn the WRV & Wastegate Actuator
.Tube btwn vacuum reservoir & WRV
.2015 Ford Edge SEL is an excellent car and I would buy same car again
