its obviously a dodgy sensor or connection to that sensor, what repairs have you been doing?

[l1ukeRS]

nothing to do with electrics, oil change, spark plugs spose they are ish but t all back together fine, erm bottom arms and engine mounts

[Ratty]

might just need a good run, has it been standing for a while?

also if the battery is not charged enough that can trigger the engine light as some sensors require 12v and others 5v, make sure the battery is properly charged then take it for a spin for about 30mins in all driving conditions.
