i`m not sure whether this is the appropriate place to ask this..
anyway..

sr20det typeX (J4 ecu) in a s13 hatch..

what can cause the ecu to send more than 5v to the sensors?
5.12v to be exact..
this is the supply voltage to the tps..
the tps keeps on blowing out..

i measured the supply voltage that goes to the ect (engine coolant temp)..
it shows 4.89v..

if the power is shorted to positive, it would give 12v right?? (or whatever the batt voltage is)

i`m stumped.

any help is appreciated..
thanks
