Edge of Reason Posted January 2 Share Posted January 2 Whilst out today, I had a warning saying the battery in my key needed replaced. On the return journey I noticed the engine management light on and assumed this was a generic warning lamp linked to the key fob battery. When I got home I replaced the key fob battery and the written warning has disappeared from the dash, but the engine management light is still on. How do you identify what the issue is that’s causing the engine management light to come on ? My car is the current shape, 2021 MY Kuga ST Line X with 2 litre eco blue diesel.

unofix Posted January 2 Share Posted January 2 You need to use a Windows laptop with FORScan software. There are also versions of FORScan available for android and iPhone.

Edge of Reason Posted January 3 Author Share Posted January 3 Cheers for replies. My laptop won’t operate unless plugged in the mains as it’s crap and old, so might not be an option. I thought there might be something in the dash menu that indicated what the error might be. As for my warranty. Unfortunately 23rd December was three years up and I didn’t renew it !! Seemed like a good idea at the time. Quote Link to comment Share on other sites More sharing options...

It does all the same reading as the Windows version, and even resets service indicators and clears DTC's. The only thing the phone version can't do is make programming changes. 1 Quote Link to comment Share on other sites More sharing options...
Edge of Reason Posted January 5 Author Share Posted January 5 What a doughnut. I remembered today I had the Ford Pass App and having now checked for my error I got this… I’m none the wiser but at least it doesn’t appear serious. I have now ordered an OBD connector from the previous link and I’ll download Forscan once the OBD thingy arrives. 1 Quote Link to comment Share on other sites More sharing options...
Edge of Reason Posted January 13 Author Share Posted January 13 Well I got my OBD thingy and Forscan and the fault code seems to be P24AE - Particulate Matter Sensor Circuit. Does this mean I need to buy a new sensor ? If so where is it located and how do you swap it over ? Any help would be greatly appreciated.

unofix Posted January 13 Share Posted January 13 That's not a very common DTC 🙁 I would have my doubts that you need a new sensor on a 2021 car. Have you tried to clear all DTC's with FORScan ? If not I would do that now, this may just be a random code. Perhaps if @iantt sees this thread he might be able to offer some help. Quote Link to comment Share on other sites More sharing options...
Edge of Reason Posted January 13 Author Share Posted January 13 Yes I cleared all faults and ran the car. Two days later it came back on. This morning I again cleared the codes and two hours later it was back on. There is no loss of performance with the car. It runs perfectly normally. I’m just concerned that doing nothing might allow a minor issue to become a major one. MOT not due til December but I think having the engine management light on might be a failure ??

unofix Posted January 13 Share Posted January 13 Yes management light on is an MOT failure these days 🙁 If the DTC keeps coming back then it does sound like there is a problem. If the issue becomes serious the car will go in to 'limp' mode to avoid causing damage. Do you give your engine a good run out at least once a week ? The EcoBlue engine doesn't like lots of short runs without the chance of getting really hot now and then. I suspect that this is just being caused by a build up of Soot.

Edge of Reason Posted January 13 Author Share Posted January 13 My car does do a fair amount of short journeys. After I cleared the codes this morning I took the car for a good run, in sport manual mode so I could keep the revs a bit higher, hoping the DPF would do a regen. Unfortunately during that journey the light came back on. Quote Link to comment Share on other sites More sharing options...
unofix Posted January 13 Share Posted January 13 From what I understand, the problem is that the level of soot being measured in the exhaust gas after the DPF is too high. To me this does not mean that the DPF is blocked, more that the level of soot inside is high probably due to the DPF needing to do a regen and burn the soot and convert it to ash. You can with the laptop version of FORScan actually force a regen of the DPF. I don't know if you can do that with the mobile phone version. OR...... If you get the engine nice and hot, then drive it at a constant 60mph for at least 30 miles then there is a very good chance that it will begin the regen process itself. Do not switch off the engine if the regen process starts as you must allow it to finish. Quote Link to comment Share on other sites More sharing options...
Edge of Reason Posted January 13 Author Share Posted January 13 That was my thought, to do a regen. I have the laptop version of Forscan but have only just got it and really have no idea what I’m doing. The attached is a photo of my laptop screen. Apologies for the glare. I thought there was a way of forcing a regen, but can’t see how and don’t want to bugger up my car by fiddling. I’ve heard horror stories about folk bricking their cars.

Edge of Reason Posted January 13 Author Share Posted January 13 That’s why I tried today to drive in sport auto for a while to try and get the engine hot due to higher than normal revs, hoping it would do a regen. Is there something that actually tells you it’s doing it ? Quote Link to comment Share on other sites More sharing options...
unofix Posted January 13 Share Posted January 13 When you have the app connected to the car, scroll down and select "Service" you should then be able to look for 'Regen' Once started it takes about 45 to 50 minutes. It will use quite a lot of fuel (about 10 litres) and the exhaust will get crazy hot. The option of going for a 30+ mile drive at a constant 60mph might be a better option for you.

Edge of Reason Posted January 13 Author Share Posted January 13 Yes that was my thought. I drove for over an hour. I don’t have a motorway near me so being able to travel at 60 constantly isn’t an option. I have the Edinburgh Bypass but that’s only 15 miles long roughly and driven on by idiots who pull out in front of you or other stupid behaviour making a DPF burn unlikely. 1 Quote Link to comment Share on other sites More sharing options...

The most common sensor I replace is particulate matter sensor , but normally it relates to particulate matter temperature sensor circuit open. ( The same sensor) can't remember the DTC code. That failure can and does occur at new. So wouldn't be surprised at all if the sensor is faulty. 1 Quote Link to comment Share on other sites More sharing options...
Edge of Reason Posted January 14 Author Share Posted January 14 Good to know (kind of). Any idea where the sensor is located and how easy it is for a non-mechanic to swap ?? Quote Link to comment Share on other sites More sharing options...
iantt Posted January 14 Share Posted January 14 Looks like it could be a bit of a fiddle to loosen the sensor. It's removed from underneath. There's only 4 wires on the connector. 12v , earth and canbus. . The sensor comes with a module assy . They are quite expensive so personally I would get a garage to confirm the sensor is at fault before getting it changed. 1 Quote Link to comment Share on other sites More sharing options...
