Hi .I have a fiat panda 2005 169 1.2L. I bought it 2 months ago. Yesterday had to climb a very high cliff street and accelerated quite a lot(over 6000 rpm). I then parked it. In the morning i started the engine and drove for 10 minutes The engine heated up on red and everytime i was accelerating sounded like a traktor. I checked for erros and its p1325 (knock sensor - intermittent). I bought the sensor but i can't find the place for it so that i can change it. Anyone would be helpful..Thanks. I have read about knock sensor on wikipedia and i know what it does i need someone that can point me to how to reach it or if I have to take the entire manifold out.
Well what I found out from what you told me is just a description not actually a cause...or whati issues could have triggered a knock sensor error.I found the sensor and its behind the engine not in front.
Coolant is fine.
about 10 minutes. then the temperature level goes to red and then it slowly loosens power while I drive no matter the gear .
Then suddenly it stops he engine for a while(10-15 minutes) and if I try to start the engine ...there is no chance. I read that the ecu (as a protection) it shuts down the engine so that it doesn't ultra heats up. after the 10-15 minutes when the engine has cooled of a but it starts again. But my curiosity was that. If it is a sensor why it makes the sounds(just as a reference) like its a whole in the exhaust pipe or no exhaust.
The code is p1325(it was part of my question description)
The fans are working...i checked that. What i dont know is where are the sounds coming out from when i accelerate. My logic tells me that if a knock sensor fails with no sound in the engine then it must be the sensor...but if a sensor is gonna be changed and there is still knoking then there is no point chnaging the sensor.What is odd is there are no signals or warning light on the dashboard. At least the service one
It has a manifold leak...but i thought if its external leak then cooland should be leaking under the car as well ...it seems its internal.Can i fix if myself?
This mechanic is changing my spark plugs and those cables that goes in the other side of the spark plugs.And he is cleaning that part where the air filter connects (engine side) he said it's oil in there. And that my car eats oil and water thats why it overheats. He said might be something with the compression inside the engine and mught be the inlet manifold.The thermostat works normally and ventilators do start when reaching a hoter temperature. He said if I need to take the head gasket out and change it then will have to take it to a specialist to remake the edges so that the new H.gasket comes. neatly. I hope I dont need to change the whole engine.
Hi Draos .
Going from what your mechanic says looks like a headgasket problem .
This is what can happen if you overheat the engine .
This would explain your symptoms.
What he means is the head will have to be checked for cracks and to check if the head is warped ,if warped will have to be machined .
Have him do a wet and dry compression test to make sure the rings are still good, if the bottom half proves good just replace the head gasket and have the valves reseated.
This should be done if headgasket being replaced .
Please rate my help a good to excellent if you are satisfied .
If not ready to rate don't rate poor or bad service as we can continue to work on this issue or I can opt out and recommend another expert .
After accepting there is no extra charge for further assistance.
If I don't reply soon I will as quickly as I can when i get back on line.
Kind regards Greg
He said to fix the headgasket and he is sure thats not the problem its 400 to change the engine is 550.Non of them are a guarantee that all is fine. But if i spend 400 to fix and its actually the whole engine then ill have to add another 500 for another used engine change. The car value is 1000 and the scrapyard pays me 150 if i want to scrape it away. A new engine is 1000 a used one is 150(around 35000 miles)-350(65000 miles). What do you adivese. You are not located in London are you.?
