    i have a 2014 Freightliner with code eng 1 spn 51 fail 4. I just had it in the shop 4 days ago and they replaced the throttle intake valve. Please help I’m low on funds and want to know if I can be able to do it myself.

    If they changed out the throttle position sensor, it may be that they didn’t calibrate it using Detroit Diesel Diagnostic Link.
    Without the software you cannot do it yourself.
    But would only take less than an hour.
