gordonm Posted April 28, 2018 Report Share Posted April 28, 2018 Been working on my car past few weeks and today when i fired it up i see the engine management light on, so connected up my laptop and see the error fault code 50 An Temp 3 below. Does that sound like the map sensor or maybe the wiring is damaged? Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted April 28, 2018 Report Share Posted April 28, 2018 Its a temp sensor input, whats connected to AN Temp 3 ? and what are the error values ? Quote Link to comment Share on other sites More sharing options...
gordonm Posted April 28, 2018 Author Report Share Posted April 28, 2018 Hi Thanks for the reply. I really don’t know much about this at all so apologies in advance! How do I find this out? Is it all within the pc link program ? Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted April 28, 2018 Report Share Posted April 28, 2018 Yes PCLink see attached picture for the settings. You can see all the runtime values by pressing F12 and selecting Analogue. You can clear faults once fixed by going ECU Settings and Clear ECU Fault Codes. gordonm 1 Quote Link to comment Share on other sites More sharing options...
gordonm Posted April 28, 2018 Author Report Share Posted April 28, 2018 Thank you very much! Ok, will look Into this tomorrow. Hopefully it’s an easy fix! Quote Link to comment Share on other sites More sharing options...
gordonm Posted April 29, 2018 Author Report Share Posted April 29, 2018 Ok, have had another go and the details are AN T3 is connected to MAF air temp and the value is input at 0v ground. I've got a sensor connected to the ECU on my upper intercooler pipe. Sound like a broken wire to that maybe? Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted April 29, 2018 Report Share Posted April 29, 2018 The ECU has internal Pullups on the ANTemp inputs, so you could try disconnecting the MAF, if the voltage goes up to 5v then the sensor is at fault, if not the input pin is shorted to earth somewhere. gordonm 1 Quote Link to comment Share on other sites More sharing options...
gordonm Posted April 29, 2018 Author Report Share Posted April 29, 2018 I don’t actually have a MAF on the car though. Filter goes straight onto turbo Quote Link to comment Share on other sites More sharing options...
gordonm Posted April 29, 2018 Author Report Share Posted April 29, 2018 Should have said that before. Filter, mafless inlet, then turbo Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted April 29, 2018 Report Share Posted April 29, 2018 As long as ANTemp2 is working and set to Inlet like the base map you can just turn that ANTemp3 MAF Temp to OFF dont forget to goto ECU Settings and clear ECU fault codes. gordonm 1 Quote Link to comment Share on other sites More sharing options...
