    Just trying to understand if it's the case to buy a new sensor or to search an other solution...
    Gus,

    No - it would be extremely unlikely that the sensors are faulty if they work on the other car.

    I would be tracing the wire back to the ECU from the sensor, and make sure that it is reading the same value as it is at the sensor with a multimeter.

    If the cars are identical, you could also try swapping the main ECU

    @ happygu: yes we already swapped the ECU, and at the first test was code 55 (no error), after the engine start back to code 13... :-(

    @ kevin07: sorry, i'm italian, and i didn't exactly understand what you mean. The 6 sparks are clean, just checked last week. Which exactly is the O2 sensor?

    OH yes got it! No, that we didn't change it, but do you think it could be the cause for all these problems?
    Can I take it off just to do a try or It should stay there?

    I would say so but I'm no mechanic, have a read of this: http://o2sensors.com.au/static/why-r...oxygen-sensors

    I assume if you just disconnect it and its the cause of the problem then the problem will still be there, do you have one on the other vehicle you could swap over?

    Thanks man, the link is interesting and surely I'll take a look at the sensor. Anyway I did the test for that sensor (2000rpm for 10 second) and it's good: the check light on dashboard makes 7/8 lights in 1o second = good!
    What about the fact that the radiator liquid goes down? any ideas?

    thanks all mates

    if and when you take out the o2 sensor you will probably find that it has fins,these fins should all be open about 1/8 of an inch you will find that they have closed up. water one do you have any coming out the back. when ichecked my o2 sensor with a snap on reader all it said was running lean.

    Hey Kevin, sorry but your english it's lil bit tricky for my Us english, sorry but i don't understand very well...
    I don't see what's the problem with the o2 sensor in the case described in the first post.
    The o2 sensor is working perfectly as saying the checking test (2000 rpm more than 6 lights in 10 seconds).
    The problem still about the coolant circuit (error 13) and the car continues to have performance's problems even after all the pieces we've changed.
    That's why we are asking to you australian patrol guru guys ;-) We finished our shoots :-(
