Hi to everyone! First I would like to commend this forum. It's good to know that there is such awesome forum. Now to the problem. I have GP 2006 1.2. Recently when I tried to turn on car, the engine was started and brought up to 1200 RPM and then abruptly shut down. Then I re-start the engine, the same story ... and so a dozen times ... After that, car is start normally. The next day the same story... (I figure out that when car is warm that's doesn't happen ) I went to a mechanic and did a diagnostic. He told me that some sensors aren't working (RPM and temperature sensor). I bought the sensors and replaced them, but the problem remained unresolved. Then I went to another mechanics and did diagnostics again. Again I was told that the same sensors don't work... I bought the sensors again and replaced them. Problem is still unsolved...:( :( :(
Does anyone have an idea how to solve this problem
 
If that sensor doesn't work "yellow engine" lamp will be on, right? But lamp isn't on. I uploaded video on YT but they delete it :( I was record how I try to start engine.
 
no yellow (engine) light would not be on because the 'car' doesn't know how hot the outside air is does it. The ECU may think it's 70degrees because the sensor says so but it cannot verify it so accepts that 70degrees is the real temp when it's actually 5 degrees etc
 
I wasn't few days home so i haven't seen this post. I buy this sensor so i will try to change it today. Tnx to all on fast replays :worship::worship::worship::worship::worship:
 
I cleaned it, then went to the service to re-calibrate it. Last time when i was at service they told me that have some error related to 1 and 4 cylinder, but i don't know how then motor work when he worm up? If there any errors on cylinders they wouldn't work when they worm up? Or maybe they will?
