Alrighty Ford Fans Im in need of some help!!
I have an FMS 65mm t/body & was setting the TPS voltage to .7v
Ok no probs there but when I checked the WOT variable the multimeter came up with an "OL" meaning it was way too high for that scale. Changed the dial & came up with some stupid high voltage.... Any clues on how to set the WOT to the normal reading??? 4.5v from memory or whatever it is?????
thanx in advance people

The TPS should vary between 0.5 Volts closed throttle and 4.5 volts open throttle, So I assume you had the throttle open - WOT. Nothing is wrong.

ok but when I check the WOT reading its like way higher than 4.5v any ideas

Check the tps is OK by disconnecting the plug and measuring the resistance and voltage. The resistance between the top two of the wires at the TPS should be 3000 ohms with the throttle closed and 500 ohms with the throttle open. The voltage between the middle and the bottom wire at the disconnected plug connector (not the TPS) should be 5 Volts.

Jeeze remember the days when if you wanted your car to run better you just changed the jets on your 4 barrel Holley.

I'm just joshing but are you speaking English??

Cheers guys

I like the new technology. Half the time it tells you what's wrong and generally it's quicker, easier and cleaner to test and fix.

I just thought it sounded funny You guys going on about WOTs and OLs etc

I'll shut up now
