My name is AL and I have a 1994 Jaguar XJ6 Vaden Plas .... My check engine light just came on & the VCM read Fail 14 ... can someone help me out?

 

Welcome to the forum AL,

I've copied this question from your Intro to XJ40 forum. Members here with the same model will be able to help.

Hi there, FF14 is a code for a coolant temperature sensor out of range (faulty) - Sometimes this can simply be a bad connection at the plug, try cleaning the contacts and clearing the code first.

To clear the code, disconnect the neg battery terminal for a minute. Make sure you have the radio code and leave the doors unlocked when you disconnect the battery.

If the code returns, replace the sensor -

I uploaded S91_AJ6 4.0 Engine Management in the large file area or GUS should have it on his website.

All you need to know about the AJ6 diagnostics.
