    Default Need an ECU - z20net

    I think my ECU is faulty on my signum 04 plate 2.0 turbo

    replaced the EGT sensor and the code says still open circuit

    checked voltages and they are fine from ecu

    reference temps are -6441c and tis says replace ECU

    checked resistance on ecu loom at it is near enough zero

    even put a 2.2k ohm resistor on end of loom and checked resistance from ecu connector and it what it should be

    there is no resistance figures on the egt sensor however tis does not ask you to check for resistance on the sensor

    so therefore need an ecu to check before i go out and get it replaced if possible

    i have opcom so i can program the ecu in if need be
