Sinisha Posted June 23, 2015 Share Posted June 23, 2015 Hi everyone (sorry about my English)my S-max won't start when the engine is warm. If I turn off normally warm engine and I want to start it after 2-3 min, dash board temp instrument shows 120 C and than the fan starts to work on his second speed; and engine malfunction is shown on board. In normally conditions fan newer works on his second speed which is very strange and funny! Sometimes I have to try 5-6 times to start the engine. In meantime I'm waiting for working fan to stop. After 5-6 attempts to start the engine it will start and the temperature on the board instrument immediately will decrease in normal frames, on 90 C. Only one error code is appeared (P 0562 -System voltage low) and this is very strange (for me) because what is the connection between engine temperature and voltage?! Today I also noticed two times blinks on hitters light which was a new moment in my problem.Does anyone have an idea? Quote Link to comment Share on other sites More sharing options...
Sinisha Posted June 24, 2015 Author Share Posted June 24, 2015 The situation is still the same.Today I did control and I saw that temp on engine head (just turned off) was 82 C but on laptop program, in real-time, the coolant temp was 205 C!?The error codes was:P 0A09 -DC / DC Converter status circuit low andP 0562 -System voltage low.

ebod Posted June 28, 2015 Share Posted June 28, 2015 Hi Sinisha, my 2.0 TDCI went through a period of doing this 4yrs ago. I did get a new battery and starter at the time, but I actually think the real problem was there was a plastic air intake throttle body that the internal mechanism jammed shut hence not allowing air in. It may be all your engine codes relates to constant attempts to start it. So it might be worth stripping and cleaning the throttle intake. 1 Quote Link to comment Share on other sites More sharing options...
Sinisha Posted June 29, 2015 Author Share Posted June 29, 2015 Thank you for your post Ian. Can you please tell me exactly what the throttle intake/body is and where can I find it. A year ago I also changed the battery so maybe this will solve the problem. Quote Link to comment Share on other sites More sharing options...
ebod Posted June 30, 2015 Share Posted June 30, 2015 I'm not familiar with the 1.8 TDCI , only know its an original Ford design whereas the 2.0/2.2 are Peugeot/Citroen units. This is a pic of the 2.0 TDCI. The throttle body is at the bottom centre of the pic with 2 sensors . a vacuum valve an a jubilee clip on it. I would imagine something similar exists on the 1.8 at the point where the intercooler pipe enters the engine intake http://www.enginesod.com/images/www.enginesod.com/large/th41421245362qxwb-engine.jpg 1 Quote Link to comment Share on other sites More sharing options...
