aaron20100 Posted June 25 Share Posted June 25 Hi all, I have a 2012 Grand C Max with an engine management light on, I've scanned it and came back with throttle body control module, I cleaned it it, erased the code it came back. I replaced the throttle body, erased the code and came back. Any ideas on what I could be? -No loss of power -No limp mode -No erratic revs I was thinking maybe MAF sensor but is this likely? I would have thought the error would point to that rather than throttle body? Thanks in advance Quote Link to comment Share on other sites More sharing options...

DaveT70 Posted June 26 Share Posted June 26 If you've fitted a replacement, that too could be faulty. Try resetting: (Takes deeeeeep breath) Turn on ignition, DO NOT start engine TURN OFF ALL ACCESSORIES (Lights, Radio A/C, fan etc etc) Lower drivers window, close doors Disconnect battery negative cable Cover negative pole on battery so as to prevent contact with cable Disconnect battery positive cable Touch negative a positive battery cable together and hold for about 5 minutes (make sure they cannot touch the battery terminals Reconnect positive cable Reconnect negative cable TURN ON IGNITION BUT DO NOT START ENGINE Ensure all the accessories are still turned off Start engine but DO NOT TOUCH THROTTLE PEDAL - at all, for any reason, if the engine takes forever to start just let it crank until it finally starts Leave car to idle until it reaches normal operating temperature DO NOT TOUCH THROTTLE PEDAL Turn on a/c and fan DO NOT TOUCH THROTTLE PEDAL Leave to idle for a further one minute Turn off engine, remove key, open and close driver's door, restart engine as normal Quote Link to comment Share on other sites More sharing options...

Quick question would this be required even with Forscan? Quote Link to comment Share on other sites More sharing options...

aaron20100 Posted June 27 Author Share Posted June 27 Thanks Dave, much appreciated. Last one from me, do I need to wipe the EML light or can I do the above with it on? Quote Link to comment Share on other sites More sharing options...
DaveT70 Posted June 27 Share Posted June 27 Should correct itself and go out IF it's a calibration issue Quote Link to comment Share on other sites More sharing options...
aaron20100 Posted September 17 Author Share Posted September 17 Hi all, I've tried the recalibration and went off for a few days then came back, the accelerator pedal is showing 15 degrees at idle, from what I can tell this is normal? Is there anything I should be checking because at the minute I am at a loss, I took it to Ford to have it scanned, all they did was tell me the throttle body was at fault and they cleared the code (I could've done this myself). I can see that there are numerous other people with the same issue but no one actually reports back as to what it was and how to fix. Thanks in advance Quote Link to comment Share on other sites More sharing options...
DaveT70 Posted September 18 Share Posted September 18 Take the cover off the side and carefully clean the contacts and lubricate, see if that cures it. Quote Link to comment Share on other sites More sharing options...
