Engine management light comes on at 90

Saturday I bought a mkiv supra (1993 TT auto grey import) and the engine area seem stock and clean but it did have a veilside front bumper which has been removed and an original one put on. It seems to drive well with a few little niggles I can probably sort but it I take it over 90 the red hazard warning light and engine light come on. The garage said it was because the active aero spoiler had been removed and Marty suggested that unplugging the little aero but behind the dash would solve this. I've removed the dash and it doesn't have an aero box thingy. Any ideas as to what this could be as other than that it's amazing. Btw it pushes well past 90 with no noticeable issues but these lights.

Worth checking to see if the ecu has stored any error codes. If it still pulls smoothly then hopefully it will just be the speedo, but as Peter said, lots of things can throw that light up

When the rain stops I'll give the error code thing a go and see what that throws up. Can garages read the fault codes or is it like my old 300zx

Ok so I've checked the fault code thing and it does four flashes then a pause then two flashes. Apparently it's a speed sensor thing or something. Any ideas
