1996 Olds Ciera has an error code P1361

Resolved Question:

1996 Olds Ciera has an error code P1361

Expert:  Bob replied 6 years ago.

I am sending you a copy of the GM trouble for tracing down the problem for your code P1361. This code relates to the ignition control and knock sensor circuit systems. The diagnostics for this are mush easier to do if you have a class 2 scan tool to assist you when running function tests. Note that any blue high lights will not open for you as they are GM access only. Thanks

 

This may assist in diagnosing the condition.
