    Its quite common for the wire to come off the sender, remove it from the tank and check the wires.

    You should stick to the same thread for the same fault so people can see what has already been advised. Resistance readings and methods of testing are posted in your original thread.

    Agreed

    If you want to try the test mentioned in the link on your other thread for shorting out the senders, the wires for the senders are

    sensor 1...brown/black and yellow

    sensor 2...yellow and brown/yellow

    Guys, should the resistance on both senders be the same or not? I have 1/5 of tank (yellow light isn't on) and one resistance on one sender is ~115ohms and on another ~10ohms. Is it wrong or not?
    Why did I start to look into this? I've noticed that when going uphill fuel gauge drops noticeably and doesn't rise back. Any ideas?
