Hi,
Does anyone know what the resistance ranges should be for the coolant
temp sensor (blue, 2 wire to ECM) and the Intake Air Temp (IAT) sensor
on an early '93 (mfr 10/92) Eurovan? When cold / warm / hot?
My EV failed the local emissions test, seems like either of these
sensors are potential culprits, with the blue coolant temp sensor more
likely.
Should I get a Vag-Com? Or do it by guesswork in steps? Starting
with the cheapest first, I could add a resistor to the IAT circuit and
replace the Coolant Temp Sensor fairly cheaply, then try the test
again to see what happens. I think I have the early '93 IAT which is
almost $90... at that price I'd rather not be guessing when ordering
parts!
thanks,
