1996 C200 - TN signal output (rpm signal) short to ground
(27) 070 = TN signal output (rpm signal) short to ground
What does this code mean? Which part I need to replace?
I felt harassed by this problem that I cannot find the source.
Many parts I have replaced such as Electronic Throttle and Fuel Pump.
Can you give me some advise? Thank you very much.
