Title: Help with fault codes (& engine missfiring)
Post by: hubbardybubbardy on 13 March 2010, 15:10:18

Hello all

I am in a pickle once more lol

Yesterday I started my 3.0 moggy and it started to splutter, appearing to missfire and struggle.  I have just done the paper clip test and it comes up with two codes 12 and 31.

I cannot find a fault that matches 12, but i did find that 31 is no engine rpm signal.

Can anyone advise me as to what could cause these faults so I can have a crack at sorting it out.

Many thanks

i wasnt running the engine when doing the test, i just turned on the ignition so all the lights came on and read the fault codes as they came up.
