Hi im trying to find a new TPS sensor for an Escort XR3i MK4 Efi without any luck. Is there an equivalent sensor i can use from a different model (or does someone have one of these?)

product code is 89 SF 9B 989 AB

My car idles fine then at around 4000 revs it drops, mechanic thinks this might be faulty.

Thanks!

 

test it with a multimeter first ben
