Title: 3lt v6 elite v reg
Post by: ashton on 08 November 2013, 18:29:21

Hi, am looking for some help - we have an Omega which is running rough.  Has been put on a diagnostic tool, The first code came up as 74 but when cleared, it now comes up as Code 31 which is crank sensor fault and says "Fault - no RPM signal".  Changed the sensor twice, cleared the code fault, runs ok for about 10 minutes but then runs rough again.  Can anyone please help.

Code 31 is not crank sensor, just means engine not running. Regards 74, try running with MAF unplugged

Also check plug wells for oil or water. ;)
