Error code on Federal '88 300E
Today my Check Engine light came on twice. When I got home this afternoon, I turned on the ignition without the engine running and read 30% at pin 3. After starting the engine it gave a nice 49%.
A year or two ago MBDoc was kind enough to send me a sheet of paper with the trouble codes. I can't find that sheet of paper anywhere now. It seems like I remember that 30% meant that all was well. If 30% is a trouble code and someone has the information to tell me what it indicates I would appreciate the help. Thanks in advance, |

The Check Engine light only comes on when engine started when warm.
Thanks for any help you can offer about error code question above. Have a great day, |

30% Duty cycle code is :
1- Fault ECT 2- Open/short between ECU/ECT As it happen when warm, I would try an ECT or Check the connector/sensor w/ohm meter... |
